Subject: Windows 98 dos box patch
Date: Fri, 29 May 2009 08:01:00 +0200 [thread overview]
Message-ID: <4a1f7964@wupperonline.de> (raw)
I don't know whether this is of any interest to anybody besides me, but my
dos editor has some extra features when running in a Windows 98 dos box, so
I made him think dosemu is what he expects by the following patch:
