If you create a '.a22' file then please put it on the KLOV thread or share it here so I can upload it there.

Announcing 'PC10' - a tool to aid in the conversion of games like 'Golf' and 'Tennis' to better games such as 'Balloon Fight', 'Mario Bros.' and 'Duck Hunt'.

Back in 2015 details to convert Playchoice 10 games were shared on the KLOV thread above. It's an excellent effort that utilises tiny PCBs to replace the security PROM found on each PC10 cart and an online tool (NO$NES) to assemble custom made instruction rom files (the instructions shown on the top screen).

To improve upon the effort I've created a tool (creatively called 'PC10') that takes the output of the NO$NES assembler, trims it to fit an eprom and then alters the checksum so that the converted game can work with the existing security IC of the host cart. There's no need to create a replacement security IC or remove the current security PROM from the cart. Simply burn eproms for U1, U2 and U3 and you're done!

The tool is open source:

This is cool, does the menu recognise the converted game?
Yes, you supply the text for the top screen in the .a22 files. You can make it near identical to the original (although sprites are not supported) or you can write what you want!

I plan to make a number of .a22 files to replicate the originals.
Currently I've done:
  • Duck Hunt
  • Excitebike
  • Balloon Fight
  • Mario Bros.
  • Wild Gunman
