This is WinterMute's CookHack exploit running off of an FPGA that's emulating the cartridge's save EEPROM using SRAM.
This hardware isn't necessary to run CookHack, but I plan to use it both to shorten the development cycle and as a fast way of transferring data to and from the PC.
The green screen is CookHack working. You can also see the "2000" on the FPGA board's LEDs. This is the last address read or written on the EEPROM. It changes to 2000 as soon as CookHack loads, since it's reading just past the end of what would normally be the game's 8KB save EEPROM.
