Yesterday I was checking the cartridge dumps I was sent by Matt for “Double Dragon” and “Space Gun”. As things don’t add up with the dumps, I decided to try and get either cartridge on eBay.
Unfortunately, I wasn’t able to find either for sale, therefore I bought “Shadow of the Beast” instead. My hope is that the latter uses the same bank selection circuitry as the former two, so that I can shed some light on it and ensure it’s supported in C64 Cartridge Dumper.
The moment of clarity I had yesterday was around the way to classify Ocean cartridges. At the moment, I came up with a simple criterion:
- “Ocean type A” uses two chips (either one enabled with ROML or ROMH)
- “Ocean type B” uses a single chip (enabled with ROML)
This is now reflected in my LUA scripts for Ocean cartridges too.
I will post an update once I get “Shadow of the Beast” delivered and tested. Stay tuned!
