in fact, i don't know what is the black thing on the cart adaptator...someone knows ?
i'm even suprised by the adaptator schematic....(some some pins aren't connected,in back)
i checked the cartridge port pinout available on the net...
you think it's the direct Adress access which can be faulty so...
since the gfx are messed up, i think it was something like word/byte selection...
but it seems i need to make all the pins check with dpf connected on the Genny...
some pins are ok (like +5V/GND/CART_IN) but the adress and data pins must be tested connected
