 Can anybody still reproduce it? I tried it about ten times (also tried the clones a few times) and I never got the "bad Doink" or a crash.

 I was able to repo this when both players only press block button exactly 5 times. Also, the emulator doesn't exit, but instead just resets back to the initial boot up screen.

There also might be a difference in game behavior when you already have a nvram file created instead of starting fresh.

Another strange thing is, when I pick head to head option with both players, sometimes there is only the both of us in the ring and sometimes there is 4 competitors.

I'll attach a snap of what seems to be the described behavior.

 Well, testing various minutes with differents wrestlers, this happen (with high chances of reset the game), but has more chances with Doink of cause crash (and reset the game)

Can happen 2 things:

Select a random fighter without problems
-Or-
Appear Doink with wrong colors, this can appear in left side or right side (CPU 1 with wrong red colors or CPU 2 with wrong blue, brown or default colors with incorrect pallete)
This can occours if choose 1 or 2 Doinks with great chances

(checked in 193 version)


Tested with clean config (default options) and with free play (not clean)

 I was able to reproduce it a few times and the game sometimes froze and sometimes just reset, but no crashes at all.

Got the following though, but it is probably unrelated since nothing of it came up at the point the bad Doink appeared.

 I can confirm this is still happening in mame 0.222
I'll test it when mame 0.223 comes out, unless somebody test a current git version before.

 OK, was able to reproduce this, looks like original game bug - out of bounds fetch from routines table, and then call to address 00000000 (video RAM) where is no meaningful code.

FF8623F0: MOVE *A13(590h),A0,0
FF862410: SLL 5h,A0
FF862420: ADDI FF862480h,A0
FF862450: MOVE *A0,A0,1
FF862460: CALL A0

 apparently original game bug, in this code part https://github.com/historicalsource/wwf-wrestlemania/blob/1280555b4d041dd025198c8e85ed14b4c1c91cfb/WRESTLE.ASM#L3876
table value #7 should be not spare/zero, but move_doink routine address
