Pokémon Explorers of Sky: Emulator Setup, 13 Steps [2026]

Pokémon Mystery Dungeon: Explorers of Sky never got a remaster, a Virtual Console re-release, or a Switch port. The only way most players revisit Treasure Town, Spinda’s Café, and the Luminous Spring in 2026 is through a Nintendo DS emulator, and that single fact is why the game still pulls thousands of monthly searches for its ROM and setup process. This tutorial walks through the full process step by step: picking between melonDS, DeSmuME, and DraStic, sourcing BIOS and firmware files the legal way, mapping the game’s touch-screen-heavy control scheme to a keyboard or gamepad, and locking in the correct save type so a four-hour dungeon run does not vanish on a crash.

None of this is theoretical. Explorers of Sky uses a save chip type that still trips up first-time emulator users in 2026, its Wi-Fi rescue features died along with Nintendo WFC back in 2014, and the three leading DS emulators have wildly different update cadences right now. By the end of this guide you will have a working, backed-up setup across desktop and Android, plus a troubleshooting checklist for the eight problems that come up most often in community forums.

Why Pokémon Mystery Dungeon: Explorers of Sky Still Dominates Emulator Search in 2026

Explorers of Sky released on the Nintendo DS in 2009 as an enhanced rerelease of Pokémon Mystery Dungeon: Explorers of Time and Darkness, adding a new Shaymin-focused story arc, extra dungeons, and additional playable Pokémon. Nintendo never brought it forward to a newer platform, which puts it in the same boat as Pokémon Stadium and the GameCube Pokémon Colosseum and XD titles covered in our Pokémon Stadium ROM setup guide and our Dolphin setup walkthrough for Colosseum and XD: the only path back in is emulation.

Search interest for the game itself runs in the thousands of monthly searches, and a meaningful slice of that traffic is people specifically typing “explorers of sky rom” into Google because they already own a copy and want to know how to legally dump and play it. That demand sits apart from the general-purpose Nintendo DS emulator guides already out there. Explorers of Sky has quirks none of those generic tutorials cover: a cartridge save chip that silently fails if the emulator’s save-type setting is wrong, a touch-screen team-roster menu that most gamepad mapping guides ignore, and an online rescue feature that has been offline for over a decade but still confuses new players who assume it should work.

This guide treats those specifics as the main event rather than an afterthought, while still covering the emulator installation basics for anyone starting from zero.

How Explorers of Sky Differs From Other Mystery Dungeon Games

It helps to understand where Explorers of Sky sits in the Mystery Dungeon lineup before you start emulating it, because the setup advice in this guide is specific to the DS era and doesn’t carry over cleanly to the rest of the series. The original Pokémon Mystery Dungeon: Red and Blue Rescue Team games launched on Game Boy Advance and Nintendo DS respectively, using a different save format and a simpler single-screen interface that doesn’t depend on touch input the way later entries do. Explorers of Time and Explorers of Darkness followed as the first DS-native entries, and Explorers of Sky arrived roughly a year later as the definitive version of that pair, adding the Shaymin-focused Special Episodes, a handful of new recruitable Pokémon, and quality-of-life changes to the dungeon-crawling interface.

Later entries moved away from the DS entirely. Gates to Infinity and Super Mystery Dungeon both shipped on the Nintendo 3DS, which means they fall under 3DS emulation (handled by tools like Azahar, Panda3DS, and Lime3DS, which we cover in separate guides) rather than the DS-specific melonDS, DeSmuME, and DraStic workflow in this article. If you’re emulating the 3DS side of the series, the touch-screen reliance, save chip behavior, and BIOS requirements are all different enough that you should treat it as a separate project rather than an extension of this one. Explorers of Sky remains the fan-favorite entry specifically because it never received that kind of hardware jump; it’s frozen on the DS, which is exactly why emulation demand for it hasn’t faded the way it has for games that eventually got remade or ported forward.

Prerequisites: What You Need Before You Start

Gather these before you open any emulator. Trying to configure software without the right files first is the single biggest source of wasted time in DS emulation.

  • A Windows 10/11, macOS, or Linux desktop (or an Android device running Android 9 or newer for the mobile path)
  • melonDS 1.1 or newer (released November 18, 2025, with nightly development builds continuing through 2026) for desktop, or DraStic (commonly distributed as build r2.6.0.4a) for Android
  • Your own physical copy of Pokémon Mystery Dungeon: Explorers of Sky, plus access to a DS flash cart or cartridge dumper if you plan to create your own ROM dump
  • A legally dumped DS BIOS and firmware file, or a willingness to rely on melonDS’s built-in HLE (high-level emulation) boot mode, which no longer strictly requires user-supplied BIOS files for basic operation
  • A USB or Bluetooth gamepad (Xbox, DualShock/DualSense, or 8BitDo all work) if you don’t want to play on keyboard
  • At least 500 MB of free storage for the emulator, save files, save states, and backups
  • SkyTemple (the current community tool for inspecting, patching, and translating Mystery Dungeon ROMs) if you want to apply fan patches later

None of these emulators publish an official, locked-down list of minimum hardware specs the way a modern AAA game does, so treat the following as practical guidance rather than a hard requirement. On Windows, aim for a 64-bit installation on a modern dual-core-or-better CPU with a GPU that supports current OpenGL, since Explorers of Sky’s dungeon lighting effects run through the 3D pipeline even though the core game is sprite-based. On macOS, a current 64-bit release with hardware-accelerated graphics is enough, and Apple Silicon Macs should use a native or universal build where the project offers one rather than an older Intel-only binary under Rosetta. Linux users need a current 64-bit distribution with up-to-date graphics drivers and the SDL/OpenGL runtime libraries the specific build calls for. On Android, performance depends far more on your chipset and whether you enable enhanced 3D rendering than on a single spec number, so if an older or budget device struggles, the frame-skip and filtering adjustments in Step 10 matter more than buying new hardware.

The table below compares the three main emulator options so you can decide which path fits your hardware before Step 1.

If you already have a preferred emulator from our melonDS Pokémon setup guide or our DeSmuME Pokémon DS setup walkthrough, the general installation steps carry over. What follows adds the Explorers of Sky-specific configuration those general guides don’t cover.

Step 1: Pick the Right Emulator for This Specific Game

melonDS is the strongest default choice heading into 2026 simply because it is the only one of the three still shipping regular updates. DeSmuME’s last tagged release was 0.9.13 in May 2022, and while its GitHub repository still saw a push as recently as July 2026, there has been no new stable build to address compatibility issues in over four years. DraStic has gone even longer without an official update, though it remains the most practical option for Android because no desktop emulator currently runs well through Android’s compatibility layers.

There is one documented caveat worth flagging honestly: a popular Explorers of Sky ROM hack called Explorers Remixed has reported save failures specifically on melonDS and DraStic, with DeSmuME recommended as the workaround for that hack. That report concerns the modified ROM hack, not the original unmodified Explorers of Sky cartridge dump, so don’t let it scare you away from melonDS if you’re playing the base game. If you do move on to ROM hacks later (more on that in Step 8), keep DeSmuME installed as a fallback in case a specific hack behaves the same way.

For most players starting from scratch with the vanilla game, the decision tree is simple: desktop and laptop users should install melonDS, Android users should budget for DraStic, and anyone who hits an edge case on melonDS should keep DeSmuME as a second option rather than their primary emulator.

Step 2: Download melonDS, DeSmuME, or DraStic From a Safe Source

Get melonDS directly from its official project website or from the melonDS GitHub organization, never from a third-party “emulator bundle” site that repackages it with extra installers. The same rule applies to DeSmuME: use its official SourceForge or GitHub release pages. DraStic should only come from the Google Play Store under its original listing by Exophase; sideloaded APKs claiming to be DraStic are a common vector for bundled adware on Android.

Set up a dedicated folder structure before you install anything. Keeping BIOS files, ROMs, and saves separated makes every later step, especially backups, far less error-prone.

PokemonEmulation/
├── BIOS/
│   ├── bios7.bin
│   ├── bios9.bin
│   └── firmware.bin
├── ROMs/
│   └── Pokemon_Mystery_Dungeon_Explorers_of_Sky.nds
├── Saves/
│   └── Pokemon_Mystery_Dungeon_Explorers_of_Sky.sav
└── Backups/

On Windows, extract melonDS to its own folder outside of Program Files to avoid permission issues writing save files. On macOS, drag the app into Applications as normal. On Linux, both a Flatpak build and an AppImage are commonly distributed; either works for this setup.

Step 3: Source Your DS BIOS, Firmware, and ROM Legally

Emulator software itself is legal to write, distribute, and run. What isn’t automatically legal is downloading someone else’s dump of Nintendo’s copyrighted BIOS, firmware, or game ROM files, even if you already own the cartridge and console the files came from. The legally defensible path is to dump these files yourself from hardware you own, using a flash cart or dumping device connected to your own DS console and cartridge.

melonDS has made this easier than it used to be: its DS mode can boot using built-in high-level emulation rather than strictly requiring user-supplied BIOS and firmware dumps, according to the emulator’s own documentation. That said, a legally dumped firmware file still produces a more accurate experience, particularly around system clock behavior and boot animations, so it is worth having one on hand if you already own a DS. DeSmuME and DraStic both lean more heavily on having real BIOS files for best accuracy, though DraStic also ships with HLE boot support as a fallback.

Once your ROM is dumped, verify it isn’t corrupted or truncated before you spend hours playing on it. A quick hash check catches download or transfer errors immediately.

# Windows PowerShell
Get-FileHash "Pokemon_Mystery_Dungeon_Explorers_of_Sky.nds" -Algorithm SHA256

# macOS / Linux
shasum -a 256 Pokemon_Mystery_Dungeon_Explorers_of_Sky.nds

Keep a record of the hash from your own dump. If you ever redump the same cartridge later, or compare notes with a cartridge dumping community, a matching hash confirms the file is intact.

Step 4: Install and Configure Your Emulator for the First Launch

Open melonDS and point it at your BIOS/firmware folder through its system file configuration screen, if you’re using real dumps. Then select a renderer; OpenGL is the better choice on most modern GPUs, while the software renderer is more compatible on older integrated graphics. Start with the internal resolution set to native (1x) before increasing it. Explorers of Sky is a 2D sprite-based game with light 3D effects for dungeon lighting, and pushing resolution too high too fast before confirming the game runs at all just adds a variable to troubleshoot later.

You can launch a ROM directly from the command line once everything is configured, which is convenient if you want to create a desktop shortcut or batch file:

melonDS.exe "D:\PokemonEmulation\ROMs\Pokemon_Mystery_Dungeon_Explorers_of_Sky.nds"

On Android with DraStic, the app’s internal file browser points at a fixed folder structure under your device storage. Move your BIOS and ROM files into DraStic’s designated folders rather than trying to open them from an arbitrary location, since the app’s permission model on newer Android versions can block access outside its own sandboxed directories.

/sdcard/DraStic/bios/
/sdcard/DraStic/roms/
/sdcard/DraStic/backup/

Boot the game once at this stage just to confirm it loads to the title screen. Don’t start a new save file yet, since Step 6 covers a setting that needs to be correct before your first save is written.

While you’re in the first-launch settings, also check the frame limiter and audio buffer options. Leaving the frame limiter uncapped on a fast desktop can make the game run faster than intended, which sounds harmless until you notice dialogue text scrolling unnaturally quickly or music looping out of sync with on-screen animation. Cap it to the DS’s native 60 FPS unless you specifically want a fast-forward mode for farming floors you’ve already cleared, which is covered separately in the advanced tips section later in this guide. For audio, start with the default buffer size; only shrink it if you need lower input latency and are comfortable troubleshooting the crackling that can result from a buffer set too small for your system.

Step 5: Map the Touch Screen, Camera, and Action Controls

Explorers of Sky leans on the DS touch screen more than most Pokémon titles. Team roster selection, item management, and some dungeon menus all expect a tap on the bottom screen rather than a button press. Every mainstream DS emulator maps this to your mouse cursor or a touchscreen input by default, so on a desktop you’ll click where you’d normally tap, and on a touchscreen laptop or tablet you can tap directly.

For gamepad players, open the emulator’s input configuration screen and assign the D-pad, A, B, X, Y, L, and R buttons individually, then dedicate one convenient button (commonly a shoulder or trigger button) specifically to simulate a touch-screen tap or stylus click, since dungeon crawling constantly alternates between movement and menu taps. A layout many players find comfortable looks like this, though you should treat it as a starting point to adjust in your own emulator’s settings rather than a fixed default:

D-Pad   -> Move character / navigate menus
A       -> Confirm / context action
B       -> Cancel / run
L       -> Rotate camera left
R       -> Rotate camera right
X       -> Team roster menu
Y       -> Moves menu
RT      -> Touch-screen tap (stylus click)

Test this mapping inside the in-game menu before starting a real play session. Confirm that a simulated tap actually registers on bottom-screen buttons like the team-switch icons; some controller-to-touch mappings only register a single pixel point, which can miss smaller tap targets in this specific game’s UI.

Step 6: Load the ROM and Lock In the Correct Save Type

This is the step most first-time players skip, and it’s the single most common reason an Explorers of Sky save disappears or fails to write at all. Nintendo DS cartridges use several different save chip types depending on the game, and if your emulator’s save-type setting doesn’t match what this specific cartridge actually used, the emulator either won’t save progress or will silently corrupt the save file after a certain amount of play.

One frequently cited fix discussed on the RomUlation support forums for exactly this problem is to open the emulator’s cartridge or save-type settings and manually set the save type to 256K Flash rather than leaving it on an auto-detect or default setting that may guess wrong. Most emulators expose this as a dropdown in the game properties or cartridge settings menu, separate from the general input and video settings.

SettingWhat It ControlsSymptom If Set Wrong
Save Type: 256K FlashMatches the cartridge’s actual save chip for Explorers of SkyGame resets without saving, or the save menu never appears
Save Type: Auto-DetectLets the emulator guess based on the ROM headerUsually correct, but occasionally misreads and causes silent corruption
Save Type: EEPROM variantsUsed by many other DS titles, not this oneSave file created but unreadable or reset to blank on reload

Set this before you create your starter Pokémon and personality quiz answers, not after. If you’ve already played several hours on the wrong save type and things seem fine, don’t assume you’re safe; corruption from a mismatched save chip often doesn’t appear until much later, sometimes right after a major story checkpoint.

Step 7: Use Save States Without Losing Your Rescue Team

Save states are a convenient emulator feature that snapshots the exact moment you’re in, but they are not a substitute for the game’s own in-game save, and treating them as your only save method is a common mistake. Explorers of Sky, like most Mystery Dungeon games, can only save properly at specific points (usually at Treasure Town or certain dungeon checkpoints), while save states can be made mid-dungeon at any arbitrary moment.

The safest workflow: use the in-game save as your primary, permanent progress record, and use save states only as a short-term convenience, for example right before a difficult boss fight so you can retry without replaying an entire dungeon floor. Never let a save state sit for weeks as your only backup, since save state formats can become incompatible across emulator version updates, including the jump from one melonDS version to the next.

Step 8: Set Up SkyTemple for Patches, Translations, and Mods

SkyTemple is the community’s current standard tool for inspecting, editing, and patching Pokémon Mystery Dungeon ROMs, including Explorers of Sky, and it supports both the base game and the many ROM hacks built on it. If you later want to try a fan translation into another language, apply a difficulty-rebalancing patch, or explore a hack like Explorers Remixed, SkyTemple’s documentation on its official project wiki is the reference point most of the active modding community works from.

Keep your clean, unmodified ROM dump separate from any patched copy you create with SkyTemple. Apply patches to a duplicate file, never to your only working dump, in case a patch introduces a bug or a specific hack turns out to have the save-corruption issue mentioned back in Step 1.

If you want to go further into the ROM-hacking side of Pokémon emulation generally, our guide to patching and playing Pokémon ROM hacks covers the general patching workflow in more depth.

Step 9: Understand What Happened to Wonder Mail and Wireless Rescue

Explorers of Sky originally supported Wonder Mail, a password-entry system for unlocking special missions, alongside a wireless rescue feature that let players send and receive help over Nintendo Wi-Fi Connection. Nintendo shut down Wi-Fi Connection service for the DS back in 2014, which means any feature that relied on connecting to Nintendo’s own servers has been offline for roughly a decade.

Locally entered Wonder Mail passwords, the kind typed in manually rather than received online, still function in 2026 because that part of the system never depended on a live server connection. Documented glitches and exploits tied to Wonder Mail codes, including ones that can trigger unusual missions or recruit otherwise-unavailable Pokémon, are still catalogued on resources like Bulbapedia’s list of Mystery Dungeon series glitches, and they work the same way on an emulator as they did on original hardware.

What doesn’t exist, at least based on anything verifiable as of October 2026, is a Wiimmfi-style revival project built specifically for Pokémon Mystery Dungeon’s wireless rescue feature. Wiimmfi restores certain other Nintendo Wi-Fi Connection games, but don’t assume it covers this one. If local wireless or two-instance networking between emulators matters to you, test it with a throwaway save first, since behavior varies by emulator build and isn’t guaranteed to work identically to original hardware.

Step 10: Tune DraStic for Smooth Android Performance

DraStic runs Explorers of Sky well on most Android phones and tablets from the last several years, since the game’s 2D-heavy presentation is far less demanding than 3D DS or 3DS titles. If you do hit slowdown, check these settings in order: lower the frame-skip threshold, confirm the audio sync setting isn’t forcing a lower clock speed to match sound output, and disable any screen-filtering or upscaling option if your device has a weaker GPU.

DraStic also supports a dual-screen and single-screen layout toggle. For a game this touch-screen dependent, the dual-screen layout with both DS screens visible at once is almost always the better choice over a single-screen view that requires swiping between them mid-dungeon.

Step 11: Back Up Your Saves Before You Do Anything Else

Once your save type is confirmed correct and you’ve made real progress, build a habit of backing up your save file regularly rather than relying on a single copy. This matters more for Explorers of Sky than for a lot of games, given how long a single playthrough runs and how much time a lost save can represent.

#!/bin/bash
SAVE_DIR="$HOME/PokemonEmulation/Saves"
BACKUP_DIR="$HOME/PokemonEmulation/Backups/$(date +%Y-%m-%d)"
mkdir -p "$BACKUP_DIR"
cp "$SAVE_DIR"/*.sav "$BACKUP_DIR"/ 2>/dev/null
cp "$SAVE_DIR"/*.dsv "$BACKUP_DIR"/ 2>/dev/null
echo "Backup complete: $BACKUP_DIR"

Run that on a schedule, whether manually every session or through your operating system’s built-in task scheduler. For a deeper walkthrough of backup strategy across different emulators, see our dedicated Pokémon emulator save backup guide. If you ever need to edit, inspect, or repair a save file directly rather than just copy it, our PKHeX save editor walkthrough covers that process, though note PKHeX’s primary focus is the core series rather than Mystery Dungeon-specific save structures.

Common Pitfalls When Emulating Explorers of Sky

These mistakes come up repeatedly in community troubleshooting threads, and most of them are avoidable if you know to watch for them before they happen rather than after.

  • Leaving the save type on auto-detect and never checking it. Auto-detect gets it right most of the time, but “most of the time” isn’t good enough for a save you might invest 40+ hours into.
  • Relying entirely on save states instead of in-game saves. A save state tied to one emulator version can break after an update, wiping out progress that was never actually written to the game’s own save file.
  • Downloading a BIOS or ROM file from an unofficial “all-in-one” emulator pack. These bundles frequently include adware, outdated emulator builds, or files with subtle corruption that only surfaces hours into a playthrough.
  • Assuming Wonder Mail or wireless rescue works exactly like it did on original hardware with live Wi-Fi. The server-dependent half of that system has been offline since 2014; only locally entered codes are guaranteed to function.
  • Jumping straight to a ROM hack like Explorers Remixed on melonDS without reading compatibility notes first. That specific hack has reported save issues on melonDS and DraStic; test on a throwaway save before committing real playtime.
  • Cranking internal resolution up immediately instead of confirming native resolution works first. If something breaks after changing several settings at once, you won’t know which change caused it.

Troubleshooting Guide: 8 Fixes for the Most Common Problems

Work through these in order if something isn’t working. Most Explorers of Sky emulation problems trace back to one of these eight causes, roughly in the order you’re likely to encounter them across a first playthrough.

Before assuming any of these are an emulator bug, rule out the simplest explanation first: a bad ROM dump. A surprising share of “my game is broken” reports in emulation communities trace back to a ROM file that was truncated during download or corrupted during a transfer between devices, not an actual emulator compatibility issue. That’s exactly why Step 3 has you check the file hash before you invest real time, and why it’s worth re-checking if something starts behaving strangely dozens of hours into a playthrough rather than immediately assuming a setting is wrong.

ROM won’t load / emulator crashes on bootIncomplete or corrupted ROM dumpRe-verify the file hash against your original dump and redump if it doesn’t match

Advanced Tips for a Faster, Cleaner Playthrough

Once the basic setup is stable, a few additional adjustments make longer play sessions noticeably smoother. First, set up a fast-forward hotkey in your emulator for grinding floors you’ve already cleared story-wise; Explorers of Sky has long dungeons, and most emulators support a 2x to 4x speed toggle bound to a single key or button.

Second, if you’re running melonDS on a desktop with a controller, consider setting up a second input profile specifically for menu-heavy sections versus dungeon exploration, since the ideal button layout for navigating item lists differs from the layout you want while actively moving through a dungeon floor in real time.

Third, if you plan to explore the wider world of Mystery Dungeon ROM hacks and ports beyond the original game, our Universal Pokémon Randomizer ZX guide explains a related tool used across several Pokémon titles, even though its direct support for Mystery Dungeon games is more limited than for the core series. For Android users who outgrow DraStic’s single-emulator limitations, our broader DraStic DS emulator setup guide covers additional configuration depth not repeated here.

Finally, keep your emulator updated, especially if you’re on melonDS. Development is active heading into version 1.3, and nightly builds through 2026 have continued to refine DS compatibility, meaning a bug you hit today may already be fixed in a build released a few weeks later.

The Complete Working Project: Full Setup Checklist

Here is the entire process condensed into a single checklist you can follow top to bottom for a clean, working setup from nothing.

  1. Install melonDS 1.1+ (desktop) or DraStic (Android) from an official source only
  2. Create a dedicated folder structure separating BIOS, ROMs, saves, and backups
  3. Dump or source your BIOS, firmware, and game ROM legally from hardware you own
  4. Verify your ROM dump’s file hash to confirm it isn’t corrupted or truncated
  5. Launch the emulator once to confirm the game boots to the title screen
  6. Configure video renderer and start at native resolution before increasing it
  7. Map the D-pad, action buttons, and a dedicated touch-screen/stylus-click input
  8. Set the save type to 256K Flash manually before creating your first save
  9. Start the game, complete the personality quiz, and confirm the save writes correctly
  10. Set up save states as a short-term convenience only, never as your primary save
  11. Install SkyTemple if you plan to explore patches, translations, or ROM hacks later
  12. Test any Wonder Mail codes locally; don’t expect wireless rescue to work online
  13. Set up a recurring save backup routine before you invest serious playtime

Follow that order and you’ll avoid the two failure points that cause the most lost progress in the Explorers of Sky community: a wrong save type set after hours of play, and a save state treated as a permanent backup when it was never meant to be one.

Frequently Asked Questions

Is it legal to play Pokémon Mystery Dungeon: Explorers of Sky on an emulator in 2026?
Emulator software is legal. Downloading a ROM, BIOS, or firmware file that someone else dumped from Nintendo’s copyrighted game is generally not made legal just because you own the original cartridge. The legally safer approach is dumping the files yourself from hardware you own.

Which emulator is best for Explorers of Sky: melonDS or DeSmuME?
melonDS is the better choice for most players in 2026 because it is actively developed, with its last stable release in November 2025 and nightly builds continuing afterward. DeSmuME hasn’t had a new stable release since May 2022, though it remains a reasonable fallback for specific compatibility edge cases.

Can I play Explorers of Sky on Android?
Yes, through DraStic, a paid Android DS emulator that handles the game’s 2D-heavy presentation comfortably on most phones and tablets from recent years.

Does Wonder Mail still work after Nintendo Wi-Fi Connection shut down?
Locally entered Wonder Mail passwords still work, since that system never depended on a live server connection. Features that relied on Nintendo’s own Wi-Fi Connection servers have been offline since that service shut down in 2014.

Why does my save file keep disappearing or corrupting?
In the large majority of cases, this comes down to the emulator’s save-type setting not matching the cartridge’s actual 256K Flash save chip. Set it manually rather than relying on auto-detect, and do this before you create your first in-game save.

Can I use a controller instead of a keyboard?
Yes. Map the D-pad and action buttons normally, then dedicate one additional button specifically to simulate a touch-screen tap, since the game’s menus rely heavily on the DS touch screen.

What is SkyTemple and do I need it?
SkyTemple is a community tool for inspecting, patching, and translating Pokémon Mystery Dungeon ROMs. You don’t need it to play the base game, but it’s the standard tool if you want to explore fan translations or ROM hacks afterward.

Can I transfer my real DS cartridge save into the emulator?
Yes, if you dump the save file from your cartridge using compatible dumping hardware. Back up the original dump before converting or renaming it, and confirm the save type setting matches before loading it into the emulator.
