The issue with Fighter & Attacker is not a mamehawk problem. That's a regression of the namcona1.cpp driver introduced in recent mame builds. All other games from that driver exhibit the same problem. Last mame version to emulate it correctly was 0.194.

So, I spent the past few days testing the core. Below are the issues I've encountered so far:
1) Any game that shows an "incorrectly dumped" warning in mame won't load in mamehawk. Here's an example (The King of Dragons):

If you press any key in mame, the game still loads fine. But mamehawk prohibits you from going further.
Some other examples of games with that warning include:
The Punisher
Warriors of Fate
Karnov
Chuka Taisen
Guwange
I think a solution would be figuring out a way to bypass that screen and go straight to the game. It'd load without problems then.
2) The following NeoGeo games load the bios screen, then crash the emulator:
Art of Fighting 3
Blazing Star
Fatal Fury 2 and 3
Kizuna Encounter
All King of Fighters games except for '94, 2002 and 2003
Last Blade 1 and 2
Matrimelee
Metal Slug 2 and 3
Pulstar
Real Bout Fatal Fury 1, 2 and Special
Rage of the Dragons
Samurai Shodown 3, 4 and 5
Gaiapolis is another game that crashes the emu. This is the only non-NeoGeo game I've found that does this.
3) Pu.Li.Ru.La has [URL=

4) Many games have audio issues. Basically there's a static/beeping sound that keeps repeating constantly. It's kinda hard to explain, so I'll give some examples instead:
1943
Gun.Smoke
Trojan
Gradius
Bad Dudes vs. Dragonninja
Chelnov
Midnight Resistance

That's it for now. I haven't tested movie sync stability yet, this is only to check if the games are even behaving correctly at all.
