The PCB finish is ENIG, Gold fingers (on the edge connector) with a 45 degree bevel 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.
LSDJ users who use the custom boot logo should know it will fail the ROM check because it’s missing the last 16KB bank (which is all blank) so you will need to restore an existing save file to it first and it will work fine.
