Kevtris also has a couple of them dumped, including Melody Madness(a Tafoid-most-wanted), and Le Bomb(a kevtris-most-wanted) IIRC the PIC core needs some/howmuch? work before I can add games.*
Of the COP400 handheld driver games, maybe half of them work well. It's not as bad as PIC but yeah, CPU core emulation still needs improvement.
*: I think it's obvious but let me say anyway I don't claim monopoly on handheld emulation. Anyone is free to emulate new dumps. It would especially be cool to get more work done on MCU cores. Not just PIC or COP400, but new ones too eg. the Rockwell one for the old Mattel handhelds.
