I just recently made a repro on a HVC-SLROM-02 board using Mottzilla's FDS to MMC1 conversion of Almana no Kiseki. While the dumped (with Kazzo) game works fine in an emulator it refuse to start/work on a original console.

I contacted MottZilla already but he can't remember well what mod was needed to some Nintendo boards.
If anyone got an idea, I'd appreciate the help.

MMC1 has no IRQ. You'd have to hack it to use sprite 0 spinwaiting or DMC IRQ.

Apparently there's certain MMC1 revisions that work and some that do not according to what MottZilla told me.

MMC1 on a CPLD works better. Maybe because of power up state? No idea.

It's quite possible that it needs WRAM. If it's like most other FDS conversions (even official ones by Nintendo) it may need it. So I'd suggest using a SKROM board and see if that works.

Hmm, haven't tried that yet. Will do once I get a SKROM board. Thanks!
