- Code page translation. When mounting a directory as a drive letter, filenames are translated between guest and host according to MS-DOS code page.
- Linux: Code page translation from guest to UTF-8 (most Linux systems use UTF-8 these days)
- Windows: Code page translation from guest to UTF-16 (this means however Windows builds rely now on the Wide char versions of file I/O such as FindFileFirstW, but that has been around since Windows 98/2000, so it shouldn't be any problem today).
- CP437 (IBM PC/XT/AT US ASCII MS-DOS) code page translation.
- CP932 (Windows/DOS PC-98 Japanese Shift-JIS) code page translation.
- Some PC-98 'isms added (such as the function row).
