MAME core randomly resets the game

The two games this happened to me with are Final Fight and Fatal Fury Special…pretty wildly different types of software, there. I wondered what could have gone wrong, so my guess (?) is that it’s a problem with the core itself?

It’s the core that is just labeled “MAME” and appears as “MAME v.170” in the lower left hand side of the screen when Loaded.

If there’s a problem, I hope y’all solve it Check out the hook while my DJ revolves it

Also try another MAME core.

R3 or L3 are diagnostics or reset, I think that’s the issue

Well, I tested it out, and indeed R3 is mapped to reset the game. Interesting…is there a way to neutralize this function? I have big thumbs.
