… man 3 fails, badly. I will work it out before release. Also remember to copy this to the other MMC3 based mappers.
…thing is fishy with Just Breed
…tting new rising edges very quickly in a row.
… run mega man 3, but I did have to add yet another method to the mapper class to do it. (Just reading if the PPU is off broke the MMC5 counter instead.) Now to fix every other mmc3-based mapper.
-PPU is now pixel accurate. Meaning that many glitchy games are now completely fixed. However it also means that performance is worse. -MMC3 and MMC5 scanline counters have been rewritten to be more accurate. Fixed games: -Marble Madness -Laser Invasion -Mickey's Adventures in Letterland -Rad Racer -Slalom -Tiny Toon Adventures (the status bar was off by one scan line before) -Mega Man 3 (displays same glitchy lines as real hardware) -Every Namco 163 game (scanline counter was broken) Also passes several more of blargg's PPU and MMC3 tests. I haven't fixed all of the MMC3 based multicart mappers yet.
