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.
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 Stable 8.5.1.
