What do you use it on? Do you have dedicated hardware, dosbox/pcem, a vitrual machine of some sort?

Virtual Box VM.

I recommend emulators like 86box or PCem instead, they're much better for such old systems than VMs.

How'd you get it stable on that? IME it tended to crash even more that regular 9x did.

There are patches to fix TLB invalidation bug, memory limit, and several other things.

Bought a minipc for a project, tried Win11, didn't hate it, but was surprised how little and poor the legacy software compatibility was.

I ended up staying awake until 2am having a blast rolling a 98se VM and discovered softgpu: https://github.com/JHRobotics/softgpu

Not GP but I have had the same experience. I exclusively use 86Box for anything older than XP these days and it works fantastic. The ability to swap in whatever hardware you want is so much fun.
