zBoy (GB)

zBoy is a multiplatform open-source Gameboy emulator created by Mateusz Viste. This emulator provides many handy features such as a convenient way to load and save your games, the ability to perform both manual and automatic PCX screenshots, support for internal battery emulation, and more. You can even play your retro games using your keyboard, joypad, or even both.

This software also supports many additional features such as intelligent saving of hi-scores, screen resolution improvements using various graphic algorithms (Scale2x and Scale3x), and a functional 2-Gameboy link-cable emulation on LAN - making it one of the few emulators capable of doing so. Above all else, zBoy has a unique feature where the developer attempted to colorize some of the most popular Gameboy titles - allowing players to revisit their favorite retro games in their multi-colored glories.

Although zBoy is mainly available on Linux, Windows, and DOS, the provided source file can be easily compiled to create a port for other systems.
