PSP Developer Homer announced that he will be updating his amazing Gameboy Color emulator, Homer's Rin GeMP. The new version will be called GeMPē and will feature a completely rewritten UI!
Sadly that is all the information I can bring you because as of Febuary 18th, 2008 when then announcement was first made, Homer had barely begun work on it. Hopefully more news will be coming soon!
Note: This announcement is over a month old, but I have seen no news of it anywhere, aside from his site, and it definitely deserves being known.
