Copier program between FAT32 and ProfROM MFS virtual disk

[Alex Rider]

Is there a copier program that can copy a TRD image from FAT32 to or from a virtual TRD image slice in this MFS ProfROM partition?

IMHO there is no such copier, but you can use some emulator with ZS Scorpion support. Mount a trd as a disk image and copy files to a mounted virtual disk using any ZX copier. I could show you the process via Skype if needed.
