I was testing Celeste Mario Hack and found out that apparently MMC5 mapper is not emulated correctly.

Reproduced on my setup. MMC5 was not fully tested. I'll take a look.

Note: maybe this NES_MISTer issue is the answer. To be checked.

Extra RAM bug fixed but still buggy

This should be fixed in 0.9.
