 I started this project because, even though several other emulators had been written and ported to the

 - Emulates `MBC1`, `rom-only` and `MBC3` cartridges. Adding support for other mappers should be easy to do.
-- Backs up cartridge ram on exit (no save states).

 computationally intensive to run.
