Microdrive or +3 Disk support when saving & loading

[boriel]

Unfortunately not, but maybe there is a library to use the microdrive.
If I find out about something, I will post it here.

Also, if you know how to access the microdrive from ASM I can guide you to create your library.
ZX Basic allows using ASM, so it's possible to create a library for the microdrive.
