At least one of the slow doors is already configured to use a FOSSIL driver.  The BBS software I use (Synchronet) has a built-in FOSSIL driver, and I'm using the door's command-line parameter to tell it to use a FOSSIL driver.

I might look into that.  Thanks.

I really only installed dosemu2 for TradeWars 2002.  Other doors seemed to run okay with dosemu.  It seems the tradeoff with dosemu2 is other doors don't run as well as with dosemu.. :/

That's a bummer.  :/
