DOS4GW.EXE Version 2.01a and Alternative DOS Extenders

DOS4GW.EXE
The TenberryDOS extender DOS4GW.EXE was used by many early DOS games. I still enjoy playing many of these games and DOS4GW.EXE is usable with DOSBox, so they can be played on Linux.

However, the version of DOS4GW.EXE that was included with the game was whatever was current at the time. The most recent version that includes many bugfixes that possibly affected the games when used with DOSBox have been fixed in the latest version, 2.01a.

It's not free at US$49, but you can downloaded it here. Simply substitute it for whatever version of DOS4GW.EXE your game provided and enjoy the bug-fixed goodness. Tenberry also makes a "high-performance" "pro" version of DOS4GW.EXE, but it costs $300. I think that they could sell quite a few of these to hobby users (since, you know, DOS is dead) for US$5.
