Yesterday I got an original ARC: 2 diskettes and a cartridge in the box. After a short while I decided to dive into the internals of the protection the cartridge contains. With some preparation work I did a bit over 2 years ago, I found out how the protection works and I've already implemented it in openMSX and closedMSX. The cartridge also contains a ROM which required to be dumped and after a while I was able to play the game. In less than a day I was able to create both the emulation code and a block diagram of the protection.
