ROM: 4MB Flash (MBM29F033C)
FRAM: 32KB (Data retention of 20-50 years)
Most MBC3 games should work.
MBC1 games that won’t work: Any that needs 32KB RAM or requires more than 512KB of ROM.
The PCB finish is ENIG, Gold fingers (on the edge connector) to give the maximum life for insertion/removal of the cartridge.
The 4MB flash chip appears to consume about 20mA more when it’s under load for example when running LSDJ.
When you place an order, if you would like the flash cart to be programmed with a ROM, you need to supply it to us via email (you can reply to your order notification). It will be tested for 20-30 seconds on a Gameboy Advance to ensure it works, if it doesn’t work, we’ll contact you. If you don’t specify a ROM, it will be loaded with LSDJ 8.5.1 Stable.
