Ultimate PC Engine Super Grafx

Februar 27th, 2020

One to rule them all. Flagship of the PC-Engine Fleet -The Supergrafx.
A customer asked me if I can put a SSDS3 inside a Super Grafx and I loved the idea :-)

SuperGrafx2
It holds enough space to put a complete SuperSDSystem3 inside.
Now its possible to have the complete PC Engine Software Library including all CDs in one unit and it looks like stock level.

Removing the original Extension Bus makes it easier to put all the wires to the SuperSDSystem 3.

SuperGrafx7

A lot of wires needed

We call it SuperSDSystem3 inside ;-)

 

 

 

Gradius III SA1 mod working on PAL SNES

Juni 26th, 2019

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
