Well is not a cartridge, is not a game, but it’s a great retro-hardware piece that I got it on Ebay for about 10 $… If you are a chiptune artist and also have a PRO-SOUNDED gameboy you would not be able to use this guy, However my idea will be to bent this unit adding a female 1/4″ jack port, and use this unit as a small amplifier. I’ll post the tutorial if I have success with the mod.

This is cool, but… why exactly did the Chameleon Twist team make this?
You could use this with a Prosounded Gameboy if you internally Prosound it!
I have a internally Prosounded CGB and I use a small amp for it alot!
You need to talk about the Game Boy Booster now :
