In-law's gaming rig set up

[Snowreap]

There are some old games that just won't run properly on modern systems. If they're super-old (pre-CD days) they will probably work in DOSBox, but there's a middle area of games that are too new to work in DOSBox, but too old to run under 64-bit Windows 10. So as time goes on you'll be less and less able to have a single system that runs everything.

For retro gaming there's really no substitute for a retro rig to run them on. If you can find a used machine, preferably an enterprise-grade system because those have a better chance of being built to last, and put Windows XP on it (not the x64 version!) you should be able to run most old stuff. There might be a few games that actually require a Windows 95 install.
