GameYob is available as an open source emulator. It emulates GameBoy and GameBoy Color – suitable for Nintendo DS. The platform is quite complete and brings in a plethora of functions, with some of the most popular ones including fast forwarding, mappable buttons and save states. The emulator has been through a few updates in 2020, so the project is not abandoned. Further versions are expected at some point in the future. It is worth noting that GameYob will not run GameBoy Advance games – it is not suitable for this purpose.
Being able to emulate Super GameBoy games as well, this program supports the GameBoy Color Bios for all kinds of palettes, automatic SRAM saving, cheat codes, custom borders, GameBoy Printer emulation, save states and GBS music playback. It is important to know that it will scale to fill the screen too – one of the most common issues associated with other similar emulators.
