And again a small vic20 core update.
Changes:

• used bugfixed T65 core from the bbc micro project.
• auto reset when changing the memory configuration
• switched internal joystick port

Now the core works with only one usb joystick attached.
With the bugfixed cpu core more games work including Dark Dungeons which didn’t run before.

Another update for the vic20. The 16K expansion can now be disabled and I added a 3K expansion. There’s no lock to prevent enabling both ram expansion but I think that doesn’t work (but I have no idea how the real hardware would have handled it).
At least unexpanded and 3K games seems to work now but I still see problems with some basic games. They just stop sometimes with a type mismatch or similar. Anyone has an idea what that could be?
