About this game:
zBoy is a multi-platform, open-source GameBoy Classic ("DMG") emulator that provides a load/save feature, can perform PCX screenshots and emulates an internal battery for ROMs that were designed to use one. It is also one of the very few emulators that make it possible to play games in 2-players mode over LAN, emulating a link between two consoles. zBoy supports many additionnal features, too, like intelligent saving of hi-scores for some games that aren't able to save their hi-scores table by themselves because of the lack of a battery-backed RAM on the cartridge, and improving video output using graphic algorithms Scale2x or Scale3x.
