[新聞] (WIP) Kale's Mame Wip - Konami Chequered Flag WIP
2011.04.29
Happiness at the glimpse of a Red Flag
While doing deprecat.h clean-ups (basically conversion of irq systems
in old drivers) I’ve stumbled across one of my oldest nemesis …
Chequered Flag by Konami. After some grinding of my teeth and a LOT
AND HALF of DASM code studying, I’ve finally nailed it down, it was
mostly a rather silly bug with the protection device, checking that
a check was true on a port by checking that all the bits were high
instead of just one like one could imagine …

Note: I’m not entirely sure that the protection is COMPLETELY
emulated, if you know the original game and notice something
wrong just let me know via the public channels, thanks in
advance.
