Hey,
I just received my GB Boy Colour from the company Kongfeng. It's a Gameboy Color clone that plays regular GB and GBC cartridges and the good news is that it also works fine with the EDGB. Now I can enjoy GBC games on a beautiful backlit screen. The only thing worth mentioning is, that when the batteries are half full, EDGB will no longer be able to flash games, you can only run the game already on the cart.
