A 32k ROM file will be generated that can be inserted into the emulator.
The VDP used by the ColecoVision is the same as the one in the MSX, as such many MSX examples will work. However, the machine is not particularly well equipped with memory so care must be taken.
You can reduce RAM usage by making static data const
where possible - this will keep it ROM rather than copying to RAM.
The Colecovision controller has a joystick as well as keypad with 12 keys. The joypad and two of the fire buttons are supported by the joystick()
function with indices 1 and 2.
The keypad is additionally supported by joystick()
with indices 3 and 4. In this mode, the joypad is returned in the lower byte and the upper byte contains an ascii value relating to the key that has been pressed: '0' - '9', '#', '*', 'C', 'D'
The Bit90 computer is effectively a Colecovision with a keyboard and a BASIC ROM. z88dk supports the keyboard using the -subtype=bit90
option to the Colecovision port. For the bit90 subtype, keyboard joysticks are available.
Upto 32k of RAM is available on the Bit90. Use mame -window bit90 -ramsize 32k
