The Perfect Tapto Mister fpga Console

Mai 18th, 2024

Hi Folks,

thanks to an inspiration of BedroomNinja talking about a more PC-Engine like Tapto Reader 3D Printing Design – my idea was born to make the ultimative Perfect Tapto Mister Unit.


I used a broken original PC-Engine and put a DE10 Nano including a RGB-Analog Board into it.
After some triming and some 3D printed peaces it fits into a PC-Engine.
In between of the I/O board and the DE10 Nano I put a Fan for cooling.
I ripped of some parts of the Analog I/O Board used parts from the original PC Engine PCB  for power Button and the PC-Engine Controller Port (waiting for a snac adapter).
I used a Mini Din 8pin SMD2 Pin Compatible Port for analog RGB-Output.

Put a 4 Port OTG USB Hub inside. a tapto Reader and voila.
Here we have it: One to rule and play them all ;-)

For reference and thanks for the great tapto Project!

It is a quick and „dirty“ hack. But from the outside it looks great and is fitting for my application.
Here are some pics from inside for inspiration…









Color of Breadbin C64 RAL 1019 „graubeige“

März 5th, 2024

I have two Breadbins hopefully not yellowed and there will be a match near RAL 1019
The 3rd is a more „whiter“ breadbin (on left side) and one 1541.


The 1541  matches most RAL 7032 but you see a difference to the Breadbin lying on it




The C64 Breadbin seems to be RAL 1019









Color of Atari 400 and 800

November 24th, 2023

a friend of mine Steve Boswell suggested PLA+ eSUN 3D Bone white (Knochenweiss)


Color of Atari XE and ST Computers RAL 9006

November 24th, 2023

I checked it with a RAL Color Reader  and for not yellowed Computer RAL9006 weißalluminium seems to be the best choice.
First try:
is looking good



Color for Atari XL Printing Project RAL 1013 perlweiß

November 24th, 2023

For 3D Printing I needed the color of the original cases of the XE and ST Series. So I bought a color checking device RAL RAL Color Reader  and a RAL Farbkarte.
I checked several Atari XL Computer in different state of yellowing.

The best looking NOS Atari on the left side has the following colors.
RAL 1013 Perlweiß is best fitting for good looking Atari XL Computer not yellowed


For more yellowed units


RAL 1014 Elfenbein fitts for yellowed units like the right one.

First try RAL 1013

FRAM Mod for Sega Saturn

Juni 4th, 2020

The internal BackupRam is battery powered via a changeable CR2032.

With this mod the Backup will never get lost during battery failure.

You have to replace IC 8 (here a PAL Board 837-12135 PX PD SATURN MAIN VA PAL SD)

with a RAMTRON FM1808-70S and lift Pin 22 and Pin 28. Solder the wires to the lifted pins

Pin 22 to GND
Pin 28 to 5V

and you are done :-)

Universal Cartridge Stand for 8 peaces

Februar 27th, 2020

I found this nice looking 8Bit Cartridgestand @thingiverse

It can hold 8 peaces and I stretched it to fit for all kind of needed Console Cartridges I am using for testing when modding the consoles…





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 :-)

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.




A lot of wires needed


testing with original RGB Output from the SuperSDSystem3


Removing the original DIN A/V Connetor and replacing with a DIN 8.1 to make RGB
Output via the original A/V Port


a shieded cable to the A/V Port


and with the cover on the backside you see „nothing“.


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

u2 sram

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


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