Did you play Vs. Excitebike (not FDS) after the title screen? I'll see if I can find another ROM to test, but it's still showing the same glitched graphics during gameplay for me. No issue with Karnov or most MMC1 games. Trying another ROM of that Vs. Ice Climber hack to see if that's the issue.
The rom I used for Vs. Excitebike was "Excitebike (VS) [NES-hack v1.2].nes with a checksum of F58C99D7. The rom from the Smokemonster pack (which I sent to Krikzz in PM) has the checksum of E1AF3048.
The 2.0b rom of the Vs. Ice Climber hack booted to black screen and then played with garbled graphics when I reset to game. Checksum D732018E. The 2.1 version of the hack that also gave me a blank screen (didn't test reset to game) has a checksum of C6CCF3CC.
currently testing 1.22. VS exitebike works fine as well as Karnov.
Mapper 1: tested: kid ikarus, blaster master and ice climber on FDS
Ice Climber for FDS works for me too. It's not the same rom as the Vs. System Hack (which is a .nes rom, same with the hack of the AC Vs. Excitebike).
