Dump the ROM back from the cart and compare the dump to the file you flashed to see if they are identical

Dump the ROM back from the cart and compare the dump to the file you flashed to ...
Just did that, they are identical. And the issue isn’t present with the dump in an emulator either

very interesting - my conclusion so far is you found a bug in FP's implementation of the mapper logic.
the fact the dump matches means the flash isn't faulty and it was written correctly
both funnyplaying carts do it ?

Huh, it’s weird. Makho said it worked with no issue, i wonder if he experienced this too

Can you test that rom in the latest version of bgb? it's very accurate and might pick things up other emulators dont. https://bgb.bircd.org/

That’s the one I just used, the Intro looked perfectly normal, same version too
sudden carbon
perfect. in that case you've found a bug in the FP cart mapper!

Oh wow lol

it's probably some edge case timing problem or so, the rest of the ROM probably plays fine 😉
