EasyFlash is a cartridge for the C64 expansion port. In contrast to traditional cartridges, this one can be programmed directly from the C64. EasyFlash is a 1 MByte Flash EPROM card with multiple configurations and banks possible. It does not use traditional UV-EPROMs, but Flash memory. This makes it possible to "burn" the cartridge using your C64, no EPROM programmer is needed.
