I support this request. I'd like to have the DOS versions, too.
Have my old Timeshock!-CD as a Bin/Cue-Image in Dosbox and the Windows version installed. Prefer the Dos version over Windows version not only for the soundtrack but for the campatibility.
Thanks to DOS-Box it is just more portable and I can run it in window mode
while doing other tasks that involve boring waiting times (video coding, system repairs and so on) :-D
Now I've got Big Race USA and Fantastic Journey from GoG.
I'm a bit disappointed they didn't include the DOS versions.
The Windows versions doesn't even let you switch tasks to check your messenger (black screen after Alt-TAB) :-(
Often I also have serious performance and sound issues with the windows version. I have no such problems with Timeshock! in DosBox.
And last but not least I've not found a way to trick the Windows version into vertical screen mode.
With the DOS version you can do that. Look at the attached image. I would like to do that with Big Race USA and Fantastic Journey, too.
