Haha no problem Baymen. I hate when i can't get things to work!!!
I could have sworn i got it to work last year. And even remember thinking, why would someone pay to play this!!!
I tried a bunch of boards, PPUs, eproms, even boards with the memory modification and some without. It just keeps resetting. I can't help but think maybe the 1A belongs in another spot....??? Maybe 1D? I just can't remember.
Tried a quick google and every thread i have read is the same.
Hmm.. this is from the mame source code:

2351 PALETTE_2C04_0002
2352 ROM_END
Not sure what the unknown means. I know it works in mame....
