Bandai Datach (Multicarts)

Designing multicarts for rare/obscure game consoles is my current main interest.
I got interested in the Bandai Datach system and it's one of those systems which have no solution for Flashcarts so far...until now.



As always, the design had to be as simple as possible, while the cartridges should have space for as much games as possible.
The complete system has 7 game-releases, with 256kb each. So i designed a Multicart which has 1mb of space. (for four games, selectable by dip-switch)

One game (Battle Rush) was a small challenge, as it uses a X24C01 eeprom for saving your built robots. Without this eeprom, the game boots and let you design your robot, but nothing more, as it clearly needs the saved robots for starting a battle.
X24C01's are not easy to find and also not cheap these days, but luckily we only need it on one cartridge!


The cartridges fit perfectly inside the Bandai Datach and the PCB's should even fit inside the original cartridge-cases.

Here are the DIP-Settings for both cartridges:







At https://retrostuff.org/category/bandai/datach/ you can even find many of the needed Barcode-Cards, just print it and you can use it with your Datach-Barcode-Reader.

Prices:
4in1: 15EUR
3in1: 18EUR

both carts: 30EUR

Shipping worldwide is 15EUR

PS-IO Switchboard for PS1 (incl. Modchip)

As i needed a second PS-IO switchboard for my other PS1 console and didn't want to wait another 4 weeks until it arrives here i made my own ones.

Firstly, i made a 1:1 copy for the original switchboard. It's perfectly working and can get installed with the same instructions as the original board:

PS-IO Switchboard 1:1 clone


As i also wanted to install a Modchip inside my PS1, i made a second version of the switchboard, which also includes a MM3 Modchip on the board.


PS-IO switchboard with ModChip (installed on a PU-22 board)




This is a clean solution if you need a modchip inside your PS1 and a switchboard. It will save you 2 wires to solder and it's easy to install.

Old solution, installing the PS-IO switchboard and MM3-Modchip seperately (on a PU-17 board)


I have some of those boards left.

The 1:1 Clone will cost 8EUR
The Switchboard+Modchip will cost 11EUR


Just use the contact form below if you need one.

Flashcarts/Multicarts for the Tomy Pyuuta/Tutor

Ever wanted to play the complete Tomy Tutor/Pyuuta game library?
It's possible now, with these flash-/multicarts!

16kb/8kb Multicart

This multicart can play all available 8kb and 16kb games. It includes 28 games, which are easily selectable by dip-switch.

8kb/16kb Multicartridges

The full game-list and DIP-settings can get seen/downloaded here.



3D Multicart

The game-library of the Tomy Tutor/Pyuuta included three 32kb games or "3D games" like they are called most times.
This multicart includes all three 32kb games and it even includes the extremely well homebrew game Pitfall.
The 32kb Multicart comes inside an Sega Megadrive cartridgeshell, which fits perfectly inside the Tomy Tutor/Pyuuta.

3D Multicart

As the Tutor/Pyuuta only had the addresslines for 16kb on the "normal" cartridge-slot, you needed a "Game-Adaptor" to play these 32kb cartridges on these consoles. This adapter plugs into back-socket of the console.

Game-Adaptor

As these adapters are pretty rare today and even if you get one they are very expensive, i also reversed this adapter and rebuilt it in my own design.

Game-Adaptor, needed for all 3D game cartridges and the 3D Multicart

this design is way smaller as the original adapter and because of the twisted sockets it takes nearly no additional space beside the console itself.


You can watch two reviews of these cartridges and all games here:
