  • Gradius III SA1 mod working on PAL SNES

    thanks to Vitor Vilea for the great Gradius III  port with use of the SA1 Chip.:-)
    No its time to make it real. As I done SA1 mods before with a 3,3V Flash chip I used this way

    you need:

    1x AMS1117 3.3V voltage Regulator Low Drop SOT-223

    1x 100nF kerko (yellow)

    1x MX29L3211 Flash

    1x AS6C1008-55SIN RAM (1M)

    I patched the japanese Rom and duplicated it 8 times (not sure if needed).

    copy /b g3jpsa1.bin + g3jpsa1.bin + g3jpsa1.bin + g3jpsa1.bin + g3jpsa1.bin + g3jpsa1.bin + g3jpsa1.bin + g3jpsa1.bin + g3jpsa1.bin 8g3jpsa1.bin

    use Voltage Regulator with kerko and wire 3,3V to the 3 detached Pins of (33,23,1) MX29L3211

    Remove original RAM and free the soldepads from green coat and place in AS6C1008-55SIN

    and ready to go without any slowdowns….

    optional RegionFix SA1 Cart working on PAL SNES

    Lift Pin 127 (5V floating) of U3 SA1 for 50Hz PAL SNES (regionfix)

     

    You can use a 28F1610 instead of the MX29L3211 3,3V Flash

    29F1610

    Here you have only to lift pin1 and set pin 1 directly to 5V
