Hey, all. (First post here, pretty new to the chiptune music scene.)
I recently ordered a modded DMG off of eBay from a pretty trustworthy looking guy. Nothing special, just has a backlight and prosound. It works fine with any normal Gameboy game (Mega Man, Pokemon Red, etc.), but when I use my EMS 64s with LSDJ flashed on it, it goes bonkers any time I press start. It gets all low pitched and makes crazy noises, and the contrast goes up all the way so I cannot see anything unless I adjust it again.
Any idea what is the issue? Could it maybe need fresh batteries? I'm using some rechargeable batteries that were in my Gameboy colors, and like I said it works fine with regular games. I can attach pictures if necessary. c:
