Ooooh... Commanders Edition... noice. Other than the graphics, I might actually prefer it over SH4... well... maybe not...
You definitely want to see the thread
SH1 is working! further down in the main list of this site. You might want to consider using
DeFend Reloaded for use of running Silent Hunter (SSI) on your Windows PC (be careful what you click on there, lots of ad junk). I have it on this machine I'm using here, a dual-core Intel E4400 on an Asrock mobo with 2 gig of ram (I still play with Commander Keen too). No issues whatsoever. You could also consult
SubSouWesPac's web site, but they do not have a community to ask in like here. Between it all, you should be able to get up and running and have sound all the way through the game. Be patient with the set-up. Ask questions.
