We will install a customer supplied triple bypass board in your Genesis/MegaDrive. It is the customers responsibility to purchase a triple bypass board and verify that they have purchased the correct board for their console. We recommend purchasing boards from Insurrection Industries. If you need to purchase a GOAC board and it is unavailable, please purchase the YM3438 and let us know in your purchase notes that you need your board converted for the GOAC. If you are not sure how to determine which board you need, please see the following page on RetroRGB.
