We recommend using our Joey Jr cart flasher to write to our carts. GB Operator is also confirmed to be compatible with our MBC3000 cart.
GBxCart v1.4a is unable to flash this cart. Please confirm support with InsideGadgets if you plan on using their hardware with our carts.
All carts are shipped in MBC3 mode with our MBC3 test ROM. Please contact us via Discord if you'd like a custom ROM flashed prior to shipment.
