Until an x86 DRC is implemented in MAME... x86 itself is dead and buried these days.
Besides, if MAME doesn't preserve or emulate these games, most likely someone else will and most likely with devastating results in terms of preservation (it all about t3h g4m3z, of course). If it's truly x86/Win32 and using stock standard PC components, I would imagine anyone who did hack the game would probably get it to run as a standalone EXE on anything from a Pentium 2 up (e.g. top of the line Brazil-spec PC), and probably also hacked up to use any 3D card at any resolution such as 1080p. Not to mention, the source code probably wouldn't be available at all, the program would never be updated so it ends up crashing on every second PC which doesn't match the author's exact specs, it eventually gets leaked, and the author quits and it's back to the drawing board four years later. Been there, done that, got quite a few T-shirts now.
