I tested this version on a real PC.

Test machine: 1024MB, MSDOS 7.1, native ( without Himem ),
NVIDEA Geforce FX 5200 (128MB)

After DOS32 is launched, some text ( blue on black ) is shown, including a copyright msg. Then a prompt appears.

If I press just ENTER, an error msg is displayed, "invalid command" or something pretty much similar.

A "dir" does display the content of the current directory, then it "freezes".

If I enter "cd", "gui" or "vesa", it just "freezes".

So there is a severe problem.

Ok, but exactly this IS a DOS extender - providing int 21h in protected-mode. If you need to call int 31h, then it's just a DPMI host.

MS-DOS forever!
