Just Desserts: Definitely, I'm happy to scan more games and hope the improve the process along the way! As of now, I've only dumped one SM510 but I don't think that other SM510-based games should pose any problems. The SM511 games are a bit more problematic as the melody ROM can't be electronically dumped (yet!). I will try to assist Sean with trying to re-dump the ROM and melody ROM from the SMB game which has an SM511 as I have a copy of that game at home and the content of the ROM is known so we can verify if we read it out correctly.
I only have two more not already dumped Game & Watch games available, Climber (SM511 based and the game that originally got me into this!) and Green House (SM510). I have scanned and traced the Climber display but will wait with trying to dump the ROM. Green House have I partly disassembled so that one will be the next one to look into. I would though first finish the DK game or at least determine if the issue found is with the dump, display files or with the emulation core. After that, I'd be happy to start dumping some of the games you have acquired
