Yeah to be clear, I replaced the internal battery. I don't know if the issue is that it isn't seated properly, it was working for a spell. But I can't solder and don't want my first project to be a 1st gen copy of Pokemon.

Anyways, I just want a "known good" emulator for the game boy. It could be a GBA emulator since that's backwards compatible, but I just want something simple to play Pokémon.

To be clear I was weirded out because an emulated copy glitched out, not the physical one. Physical one just had a battery issue.
