I've been working on MMC5 support in my emu. So far so good... I've been using this excellent doc here:

as my reference. I've only really tested 3 ROMs so far: Castlevania 3, Just Breed, Laser Invasion. They all seem to work... except I have a weird problem with Laser Invasion that I can't figure out:

Garbage appears on the Score line... seemingly random characters every time. I notice no other graphical glitches in this game... nor in the others I've tried (so it's really puzzling me)

But anyway... that's just a small thing. The main reason I'm posting is because I would like to know of the names of good test ROMs. Or really... any test roms. I'm not sure what games use MMC5.

- CV3 uses the 12k-at-once CHR setup (when 8x16 sprites are on)
- Just Breed uses ExRAM for extended attribute tables and sound
- I don't know what Laser Invasion uses

Ideally... I'd like to get names to at least 1 ROM which tests each area of the MMC5. I implimented everything listed in the previous doc except for split screen mode... which I'd like to do as soon as I can get a ROM to test with.

Games to test split screen scrolling, RAM swapping at $8000 and up, ExRAM as an extra nametable, and "Fill mode" mirroring would be great. Can anyone fill me in on some games and possibly what areas of the MMC5 they need to work?

Thanks in advance.

Which Koei games use MMC5? Those would be the most likely to use the split screen.

The only game known to use split screen is 宇宙警備隊SDF ("Uchuu Keibitai SDF (J).nes"), and only during the intro (for displaying the ship stats).

P.S. If you don't get this note, let me know and I'll write you another.
