Msx basically consider floppy drives a non-msx feature.
Msx floppy disk drives are basically of two categories:
I/O mapped
memory mapped.
there are also variations in mapped addresses.
Some games, in disk format have their access methods, so basically the floppy are not MSX-DOS formatted, but the game start itself from the floppy boot sector, then while running, read directly from disk the needed data.
What is not clear to me is this: while it's easy to access without BIOS, say , the psg, (because we all know PSG mechanics or addresses), how about direct floppy disk management?
Are there some games that directly access the floppy hw without bios?
