MARIO Chip Pinout!

Post by BokuNES »

someone has the pinout scheme of the MARIO CHIP (the starfox 1 fx chip), i tried to use the nocash snes document to see the pinout, nocash says on that document that the MARIO CHIP, the GSU-1 and the GSU1A shares the same pinout distribution, but testing the pins with a multimeter shows that the MARIO CHIP has a diferent configuration, so, im looking for the MARIO CHIP Pinout, im specifically looking for the lines SRAM a15 and the SRAM CS2 pins on that chip. best regards!
