Open-ED is a very simple and cheap open source Genesis/Megadrive cartridge.
The cartridge does not have its own processor or FPGA,
it is built in the old school style using only memory and discrete logic.
Cartridge design uses an absolute minimum of inexpensive components.
There are no fancy features that modern cartridges usually have, so don't buy this device unless you're sure you understand what it is.
Supported mappers:
ROM_4M Most games work in this mode
ROM_2M+RAM Some games with battery ram
ROM_4M+RAM Beyond Oasis, Sonic-3 etc
*When you turn on the power, the cartridge may start from both the menu or the game. Press reset to return to the menu.
*Cart does not have SRAM backup function, so every new game may override SRAM saves of previous game.
