More development for the C64 Cartridge Dumper

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!

    How do I reach you? I tried email but not sure you received them. -Mark

      I tried the contact form twice so I’m guessing you haven’t received a single one of them yet? I mean I can try one more time but I’m not sure and really don’t seem to believe that you’re receiving them for some reason. Mark.

      • Did you get a error when you submitted your message through the contact form?

      • Mark says:

        No, I didn’t receive an error. I’m interested in ordering the 1541 IEC product which I now forget the name of, LOL.

        … mailbox is full.

        That was the message I just got but if I click the button second time it went through but I’m not sure you’re getting them.
