I've been playing with GameSrv from R&M Software.  I used it to run all my door
games on a Windows10 32bit computer.  GameSrv runs the older 16 bit door games
that I could not get to run under SBBS and Netfoss.  I was able to get older
games like Yankee Trader and Caribean Contraband to run.  It was fun to set up.
I had to remember my batch file commands.  Luckily I had all my examples of
when I ran Remote Access in the DOS days.  I set up a RLOGIN log in and it
passes the user names over to GameSrv from SBBS.  It runs pretty seamless.
