I'm updating at least some of the software of it. Cynthcart will be the latest 2.01 version (last version was 1.5.0), and SID-Wizard the latest released 1.8 version (last version was 1.7). I was just testing the cartridge disk emulation function, save needs still some work, but load is still working with the latest patched version Hermit sent me, which uses the KERNAL load functions:
When I have some time, I'll try to implement the save function for the cartridge disk emulation, or maybe someone wants to do it for me :-) Can be updated later over MIDI.
