Cheats

Full Installation
This isn't really a cheat, just someting for the ones who don't like to change the CD's during Ps:T. This also improves performance greatly for those with slow reading CD-ROMs, as reading the information locally is faster than having to read it from the CD. This requires quite a lot of space though (about 2 GB), only do it if you can spare the gigs.
Start by copying your Planescape Torment CD's into separate folders on your hard drive, use folders like "C:\CD2" or something. Then, using a text editor (notepad works), edit the "torment.ini" file in Ps:T's main directory (don't forget to make a backup of that file, you never know :P).
Replace the lines:

CD2:=E:\CD2\
CD3:=E:\CD3\
CD4:=E:\CD4\

with the paths to where you copied your CD's, should be someting like:

CD2:=C:\CD2\
CD3:=C:\CD3\
CD4:=C:\CD4\

If you're have trouble with hard-drive space, do it to only one or two of the CD's.

Tome o' Cheats
For some mega-cheating be sure to download Platter's Tome o' Cheats. With it there's not much you can't do, check the readme for more info.
