There are lots of game reviews ine database and most were done very long ago. When looking for boxart for some old reviews were plain text files, we discovered that very few if any copies of boxart were available.
Many DOS games were shareware which generally is a playable game with maybe some additional content available for purchase. Screenshots are possible with Hyper-V.
We have vast numbers of game reviews over and above what is available with Wikipedia or any other gaming site. This is only due to the focus on games with the site.
Back in the early days of the CD-ROM, collections of games and productivity programs were common. Lower cost EIDE CD-ROM drives quickly became standard with every PC. By 1995, when Windows 95 was released, it was the first version of Windows to be delivered by CD-ROM.
CD-ROM is 150 KB/s which is comparatively slow, faster drives were marketed as multiple of the reference red book speed. DVD-ROM took over once CD-ROM speeds exceeded 24x and they too began a new cycle of faster multiples of the reference drive, Blu-Ray repeated the cycle a third time,
The advantage of the CD-ROM is the early days was capacity, Over time however hard disks grew in capacity much more rapidly. Blu-Ray discs are popular with movies enthusiasts.
When DOS runs in Hyper-V fine, finding collections of DOS games is another problem. Most games were long ago abandoned.
DOS requires MSCDEX to be loaded in addition to the CD-ROM driver. The reduces the available memory considerably.
With Hyper-V is possible to use a second disk and copy the contents of a CD-ROM to the VHD to eliminate the need for MSCDEX etc.
DOS can support many disks of 2GB each so its possible to have all DOS games available at once. DOS may be limited to 2GB per partition, but here are 24 drive letters.
LAN storage is a wild card, Netware was around when DOS was mainstream and it could handle larger disks.
