Today a GameBoy Color Emulator has been released for the PlayStation Portable by Mr. MIRAKICHI! Currently, it only works on PSP units with firmware v1.00 installed, and doesn't support sound as of yet. In addition, you must rename a ROM to ROM.GB and put it to the same folder as the included EBOOT.PBP file. Finally, http://psp.ign.com/articles/611/611529p1.html?fromint=1 also has it the Japanese PSP is going to be getting v1.51 firmware soon, so keep checking those buffer overflows from the v1.00 to aid in getting v1.50+ units caught up. Feel free to discuss the cool news in THIS Forum thread. Enjoy!
