What palette values are you using? There are four rows of colors in the palette: dark, medium, light, and pale. https://pbs.twimg.com/media/B7UN1W8CYAMeNGE.png Nowhere near fifty shades of grey Don't use two dark colors, two medium colors, two light colors, or two pale colors right next to each oth...

I'm not entirely sure what's going on, but just as a random guess... try testing using only shades of grey rather than colors, and see if it's still screwed up. Yes, it looks like your typical composite interference pattern (PAL video in this case)... and the LCD TV isn't helping either, in this re...

This can then be worked around by writing all 256 bytes of OAM. It is also the case that if OAMADDR is not less than eight when rendering starts, the ei...

Thanks for your replies

Hi everyone, I tested a simple sprite test on my NES but the sprite looked very ugly, it seems that the attribute pattern is confused. On emulators the sprite looks perfectly good. I precise my NES is a PAL one and I tested on an LCD TV that usually doesn't cause sprite trouble like this. I took som...

Thanks for your answer Sure sorry of course it's SMB3. Yes I doubled my CHR et PRG file they size respectively 262144 bytes and 524288 bytes. But they dont end by FFFFFFFF is it normal ? The rom that work in fceux dumped from the INL board sized 393 232 bytes and not 786432 +16 (from the header line...

Hi everyone,

I've got some problem with a Repro.
I've dumped my SSB3 (PAL) cartridge with Anago and write it on my INL-ROM card (MMC3 with 512 PRG-ROM and 256 CHR-R0M).
The cartridge make a back screen on my NES. Though when I dump it with Anago, i get a working .nes file.

What's the problem ?
