//creates binary file to program into 27256 EPROM to convert 49-way joystick outputs to 8-way, 4-way, 2-way, diagonal, etc outputs
//joystick outputs are connected to EPROM low address bits, data bits 3-0 are U/D/L/R (data bits 7-4 are U/D/L/R inverted)
//higher EPROM address bits select 1 of 16 mappings and reflection for x and y and rotation

//bits from Midway/Happ 49-way joystick (Williams are inverted)
#define DIR_CENTER 0x0	//MAME Analog+ website says center should be 0x8, but my Midway stick outputs 0x0 when centered

#define DIR_UP_3 0x7
#define DIR_UP_2 0x3
#define DIR_UP_1 0x1

#define DIR_DOWN_3 0xf
