I'm getting some weird input errors with Art of Fighting

>>3889427
Does that happen only in AoF2 or any other games too?

>>3889473
only aof2

Poor programming, SNK were terrible programmers.

Tried it just now. So far I don't have these problems. Maybe the problem is not in the game

>>3889492
what emulator are you using?

>>3889495
FBA core in RetroArch

>>3889497
same here

>>3889498
Don't know what's causing it then. You could try a different input driver or fiddle with the input settings. Maybe also try a different ROM. This is the first time I'm hearing about something like that.
One last idea: sometimes, some emulators have auto-fire feature. Maybe pressing the button for too long prolongs the input. But that's just a thought

>>3889427
Offhand, no. I think I might have an idea, although I haven't looked at AoF2's internals.
You can cancel out of moves and start doing another move, and it sounds to me like you are cancelling out of a move to do it again immediately.

As >>3889482 pointed out, there was some wonky programming going on at SNK at the time. The first 3 KoF games have hacked together input routines that leave a whole lot of possible move chains open, and basically you can shortcut any long lever pattern to just 3 positions. It wouldn't surprise me if the input buffer in AoF2 stayed open to new moves before clearing in the same kind of way.
