Feels like Windows 98 to me
I mean, it was developed
for Windows 98 (or DOS), initially. Original poster said "console".
I always figured Saturn, due to the quads, the mixing of 2D and 3D, the large levels, and having lots of sprites on screen at once. I still think so, but it seems to work surprisingly well on the 32X.
The Saturn and the 32X are both fairly obscure nowadays. Emulating them can be a challenge.
However, I feel like the 32X has the advantage in that it's already running on top of one of the most popular 16-bit consoles of all time. If the Saturn were less obscure, it would be better documented and emulated, and we might be seeing a port of SRB2 to it.
I don't really know much about the technical side of ANY of this, though, so maybe I shouldn't speculate on what would be easier.
The 32X port is a marvel of engineering, although it seems to have had to make a few sacrifices, naturally.
