CatFlash Midnight (8MB Mega Drive / Genesis Flash Cartridge)
Description
CatFlash Midnight is an 8 MB / 64 Mbit reprogrammable flash cartridge board for the Mega Drive, Genesis, Mega Sg, Retron3, etc.
It provides 8 MB ROM space without a mapper chip, making it suitable for large homebrew releases, demos, ROM hacks, and development builds.
Save data is stored in flash using MD Engine’s flash save mode, so there is no coin-cell battery to die and need replacing.
It can be reprogrammed as many times as needed.
The cartridge achieves its 8 MB capacity by routing the cartridge select signal to the 68000 A22 address line, avoiding the Mega-CD address collision that normally limits standard cartridges to 4 MB. Because of this design, CatFlash Midnight can't access the Mega-CD / Sega CD use.
Ships as an assembled and tested cartridge board. Manufactured by Two Black Cats Games.
Note: A compatible cartridge flash programmer is required to write software to the cartridge, such as Krikzz.
