- adds ITE, Gob and Kyra to the list of "other engines" in the introduction - capitalizes "IRC" (instead of irc) - some rewording/removed typos - adds kyra to the list of games with bypassed copyprotection - mention kyra menu - change Gobliiins note so it doesn't imply you NEED to compress the CD audio to hd (hope I didn't write anything wrong with that, please check)
