Sonic the Hedgehog 3 (EPROM prototype)

This is a prototype cartridge currently owned by LocalH. There is no visual difference between this and the final release, and it is believed to contain the same ROM. The cartridge works with a retail copy of Sonic & Knuckles. There is no battery on the PCB, therefore savegames don't persist when power is turned off. Savegames do persist while the system is powered on, however. This cartridge has not been dumped yet. It was purchased from PACHUKA for approximately $100.

See EPROM for a description of what an EPROM is.
