Currently, i have both WINSPWW2 & WINSPMBT installed on 3 desktop machines.
The oldest (desktop clone) packs an old (10 years old or more) motherboard and a Dual Core Pentium 4 HT 3.00 ghz CPU, Windows XP, the games work marvellously on that one.
I sometimes experience some short slowdown or delay in battle animations and sound effects when games are running on an HP Core 2 Dual Core with Windows 10 32 bit, but that just happens in the first 1 or 2 minutes when loading a battle. I suspect this is related to some motherboard integrated graphics BS delay.
I also had the games installed on a machine that had Windows Vista 32 bit. Very good experience as well.
I'm a "Retro" PC collector so i'm sure i'll eventually go on installing and loading up WINSPWW2 & WINSPMBT on other older machines, when i do so i'll rate them.
