Just making a note on why I made the save/load functions not work in DOS 1.0 (choosed DOS 2.0+ support instead of DOS 1.0+ support):

Confusing, 'eh?
Quote:
In CP/M and MS-DOS 1 (which did not include support for directories), the FCB was the only method of accessing files. When directories were introduced in MS-DOS 2, FCBs were superseded by file handles (what is what I use in the emulator).
FCBs were supported in all versions of MS-DOS and Windows until the introduction of the FAT32 filesystem. Windows 95, Windows 98 and Windows Me do not support the use of FCBs on FAT32 drives, except to read the volume label. This caused some old DOS applications, including Wordstar, to fail under these versions of Windows.
