oh, ok thx

@Cederick said in Super Gameboy emulation?:

The Spaceworld demos where developed to run on super gameboy hardware since the gbc wasn't out around this time

In that case, the .gb file extension would be more appropriate, although as @edmaul69 mentioned, either should work. Keep in mind that .gb and .gbc both denote a certain type of ROM. Seeing as how the Super Gameboy never had a unique ROM type, I imagine that the .sgb extension is there to tell compatible emulators to load the Super Gameboy BIOS automatically. With lr-mgba, loading a .gb file with the Super Gameboy BIOS manually enabled should produce the same results.

@monstermadeofman Already bookmarked! I want to add X and Y buttons to it, but first my GBA needs to show up from Hawaii. I'm not averse to the custom PCB idea, but I really don't want to spend $80. What "other" custom PCB have you seen floating around? The only other one that I've come across is this one that I came across while browsing Reddit but I don't have any info on the maker.

Wow. That's INCREDIBLE! Sign me up - where do I get one?!

Help! I would like to know what type of battery you used because I bought the powerboost and I would like to know a type of battery that definitely works! please help!
