* Serial Data Transfer ([Link Cable](https://en.wikipedia.org/wiki/Game_Link_Cable)) support
* Game Boy Printer emulation
* Support for multiple MBCs: MBC1, MBC2, MBC3, and MBC5
+* Save state using the [BESS Specification](https://github.com/LIJI32/SameBoy/blob/master/BESS.md) for cross-compatibility with other emulators
* Cheat support using [Game Genie](https://en.wikipedia.org/wiki/Game_Genie) codes
* Variable CPU clock speed
* Accurate PPU - passes [dmg-acid2](https://github.com/mattcurrie/dmg-acid2) and [cgb-acid2](https://github.com/mattcurrie/cgb-acid2) tests
