@ -11,10 +11,16 @@ Excel 68000 I/O is very similar to EAG, so it's handled in this driver as well
TODO:
- unemulated waitstates with DTACK
- EAG USART is not emulated
- V10 CPU emulation is too slow, MAME 68040 opcode timing is same as 68030 but in
reality it is much faster, same goes for V11 of course (see note below)
- V11 CPU should be M68EC060, not yet emulated. Now using M68EC040 in its place
at twice the frequency due to lack of superscalar.
- V11 beeper is too high pitched, related to wrong CPU type too? But even at 72MHz
it's still wrong, so maybe waitstates or clock divider on I/O access.
- V11 beeper is too high pitched, related to wrong CPU type too?
maybe waitstates or clock divider on I/O access.
Currently(May 2020) when compared to the real chesscomputers, to get closer to the
actual speed, overclock V10 and V11 to 230%. This can be done by starting MAME
with the -cheat option and going to the Slider Controls menu, hold Ctrl and press
Right to overclock maincpu.
