RiP version of Touche works fine in DOSBox because of EXE was cracked by pirates.
My full CD-copy DON'T works in DOSBox (it works fine in REAL DOS MODE, but not from DOSBox).
I have compared EXE files from full version and cracked one and found a byte which allow a full game works fine too in DOSBox!
Check my comment here

or read following:

============
Full version needs to fix one byte in main EXE (game don't works in DOSBox without this fix):
1. Copy all contents of CD to folder on HDD.
2. Open TOUCHE.EXE in any HEX-editor, go to offset 0x17ED4 (17ED4h) and replace "75" with "EB". SAVE FILE.
3. Run DOSBox and mount this folder as CD-ROM D: (or other). 4. Install & setup game as usual (installl it to "C:\TOUCHE")...
