JamesGecko: The question is vague enough to encompass a large chunk of a computer science and engineering degree, yet oddly specific enough to make one suspect that nondeplumage can't get some old game to run because his graphics card wasn't made in 1996.
Subsequent posts have done little to lift the shroud of mystery.
I was thinking about GOG, how their magic makes old games work on my computer. Games that never would before. And that led me to thinking of
KotOR 2, which won't play on one computer I had with Windows Vista and one type of graphics card, but would on another with Windows XP and another kind of graphics card.
JamesGecko: Not that nondeplumage could clear all this up with a few words. He has vanished into the mountains. Like a sage, he will appear once a millennia to speak his cryptic riddles.
I had to sequester myself in a soundproof room wearing nothing but tight leather pants and an 80s wig, until I had composed a ballad for GOG so awesome that Ronnie James Dio himself would rise from the grave to sing it. Nay, not sing.
Wail.
