This emulator is a rework of Shonumi's GB Enhanced project and can emulate games for GB, GBA and GBC. His main advantages are the tile replacement and emulator coloring. Using GBE+ you can change the whole graphics of the ROMs allowing you to turn the old arcade games in modern 3D games. Even though GBE+ misses some core functions like saving state and using cheats it can emulate almost all GBA and GB games, so it is widely used.
