What games are good for stress testing mmc3?

- blargg MMC3 test ROMs
- Incredible Crash Test Dummies
- Crystalis
- Kickmaster (titlescreen is tricky -- also poor emulation may cause it to crash after level 2)
- Megman 3 (sort of -- try going in Gemini man's stage and bringing up the pause menu -- if you're doing things wrong it'll be screwed up)
- Wolverine

Those are all I can think of at the moment.

For not so stress testing Jurassic Park has easily discernible title screen effects.

Armadillo I guess (makes non-standard uses of the scanline counter). Altough it's MMC3 it's not mapper 4 because of mirroring I guess.

Dwedit posted this topic at the same time as a topic on Pocket Heaven about his thorough refactoring of PocketNES. So I would imagine that this topic relates to emulation on a GBA.

It's TLSROM. But I'm not entirely sure how TLSROM would fit into the GBA's mirroring scheme, which ordinarily allows for 1-screen, vertical mirroring, horizontal mirroring, or 4-screen. Noticeably, TLSROM allows for diagonal mirroring ($2400=$2800, $2000=$2C00) or three-to-one-and-one-to-the-other mirroring (four possibilities), but the GBA doesn't.

(Aside: Thinking of all possible mirroring modes makes me want to play Lumines again...)

Weird mirroring modes can be simulated by playing with the scrolling and mirroring carefully, I'm just not doing it yet.

I just love those two names you made up. They should be remembered off somehow (wiki ?).
Also I don't see why you are talking about the GBA, but I'd like to do some GBA dev soon. (after all I'm pretty sure the GBA is the gaming platform I've the most used in my life (not counting PCs with emulators)).

Dwedit maintains an NES emulator for GBA titled PocketNES.

I still haven't got good results with these in my emulator. What should the message be if all is good? So far all I get is "Failed" with a number.

But SMB3 works...which, according to its iNES is MMC3. Also Bubble Bobble 2.

SMB3 was the ROM I used to debug my MMC3 implementation...seemed to be useful to get out the major obvious kinks. The title screen was missing the tiled floor for quite a while...

I also found conflicting documentation for MMC3 online. Part of the joys of trying to learn from where others have already been, I guess.

I'll admit that REALLY weird mirroring (CHR ROM nametable next to PPU RAM nametable) might be too hard to get.
