Doublepost is no good, but this deserves separate post.
Found no RLVM in this thread, so here it is:

"rlvm is an open source implementation of the RealLive scripting engine. rlvm can run some of Visual Art's/Key games including Kanon Standard Edition, Air Standard Edition, CLANNAD, CLANNAD (Full Voice), Planetarian CD, Tomoyo After, Little Busters and Princess Bride."
I'll give it a try as soon (and if) I finish Steins Gate.
