let's try to emulate kof 2002 ps2 v1.0 egcg hack
« on: January 16, 2019, 12:38:13 AM »
The King of Fighters 2002 Ps2 1.0 EGCG&GSC2007 MAME hack...
Let's try to hack this hack, then emulate it... maybe?

(more info&etc) kofonteam @ facebook

So far I found out about this hack:
x it uses a closed-source version of MAME w/the debugger key disabled - but all code for the debugger is in the exe.  (It's safe to run)
x it uses 4 instances of the audiocpu w/4 soundlatches
x sends a soundlatch to one of the 4 audiocpu's based on character selected.

Need volunteer: someone who can get the debugger to work w/the custom mame that comes with this hack.  The ecgc guys probably mapped it to some other function to hide it.  Actual mame debugger code is in the exe, though.

I try run this hack in FB Neo and have infinite resets after NeoGeo logo...
