Mario All Stars NES broken?

[Ar8temis008]

Hi, so I downloaded Infidelity's SMA NES, but can't seem to get it to work. For some reason when I save and continue in SMB2 USA the game gets stuck and endlessly loops the stage back to the beginning. It resets my lives too, so I'm thinking it's an issue with the sram. However I haven't seen anyone anywhere say anything about it. It happens in all versions on all emulators I know of on Android, Retropie, and Windows.

Double posting because it's been more then a week, and I still haven't found a solution.

It's only SMB2 that does this, the other games work fine.

Tried it in Retroarch + Nestopia, and recent FCE Ultra X SVN build. Both work okay with "Save & Continue". March 2017 patch.

Other than re-checking the original rom, I wouldn't know. Pretty fancy hack though.
