Problem with playing old dos games on the original hardware is that you can't have 20 or so PCs standing around now can you?
As for glidewrappers. www.zophar.net
had a lot of them last I checked but none of them work well enough for me to play Sentinel returns through. Most of them were made specifically with UltraHLE (N64) in mind and nothing else. If someone do manage to find a proper wrapper which won't dump all backgrounds, or render objects as white blocks, or remove software cursors or the like I'd be very interested.
