Hello , for the Disk Version I used the Krill Fastloader. It should be compatible with all existing floppy drives. Normally if you disable fastloader it should work. The only adhoc solution if you can think of is to use the cartridge emulation (from the docs I see that it should have) . It is an older cartridge ( MagicDesk) version Fizz V1.0.1_CRT with missing entry levels … please let me know if this works and I could upgrade the CRT version
