EDIT 02-10-2022: This DESIGN is OLD and not available anymore...the new AIO-Multicart with case is available here.
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.
