Looking for some inspiration for modding my spare GBC and SP's so post anything you've done with a GBC/SP or even just ideas, anything is welcome.
Here's mine: http://www.youtube.com/watch?v=TJxvT-qctwI (It's a GBC inside of a calculator )

Pretty badass. Any chance you could post a tutorial or additional shots of the inside?

Thanks!

Nice mod... Im new to all this, well ive modded before but never a GBC.. Ive done wii and 360 consoles. But I was wondering if there is a way to add and play regular nes games on the GBC. I have an nes emulator on my phone with all the nes roms but my phone is a touch screen so the buttons suck!!!!!.. I found this GBC laying around and thought Id ask around.

Gameboy SP inside sega gamegear, works flawlessly,will still play original gb games and advance, had lots of fun while i did this mod..

That looks awesome! Good work. What did you do for the charging/audio port on the GBA SP?

thank you,it uses the GAME GEAR port, i wired the gba to it, and i swaped the tip ends of the gameboy sp charger to the tip of a cordless phone that fit in to the gamegear ac/dc port.. here is youtube video of it if you would like to see it..

for audio, it uses the stock gamegear speaker, and the stock headphone, just working on using the sega wheel instead of the gameboy volume lever...

I was thinking about putting a GBA SP inside a GBC but I don't have time/gameboys, but if I ever get around to it I will make a guide, maybe.
