i know that with some 80s games with dip switches the NVRAM doesn't affect inp recordings but later games use service mode instead of dips and erasing the nvram will erase the setting as well
how i am supossed to record games with service mode options if i want to change the dafaults to hardest for an example? if i erase the nvram these settigs will be gone and the inp will be recorder on normal default mode again lol
