The NES can only display 8 sprites per scanline. If you need to have more sprites per scanline, you'll have to rotate the order of the sprites in OAM. This will cause flickering, but at least all the sprites will be visible.

Toploader worth it?

I recently found a toploader for sale. Is it worth buying? I have a toaster style NES, but it's on the other side of the country in California right now. It's also pretty old, and requires a lot of twiddling to get games to run on it. I was going to have it shipped to me, but I could get this toploa...

No I do understand. On real hardware you'd have to a power of 2 sized ROM. But there's no reason why my iNES files has to have unused banks in it. I have 24k of CHR, there's no reason an emulator can't load my iNES file with 3 banks, and emulate a blank 4th bank to make the running size a power of 2...

Building an MMC3 dev cart

So I want to build an MMC3 dev cart. My understanding is that I need to get a licensed MMC3 game, desolder the ROM chips, and replace them with EPROMs. Now I'm thinking I should get either a TKROM or TSROM board because I should be able to support any MMC3 game that doesn't use 4-screen mirroring or...

MMC3 cartridge sizes

I have a MMC3 game that needs 3 banks of PRG (16k each). However, when I build a iNES rom with 3 banks, it doesn't work. Different emulators give me different problems: Nintendulator jumps to a bad reset vector, the graphics are wrong in Nestopia, and other various things. But when I add an extra bl...
