In Steam version, you have to do three additional things:
1. Copy files battle.fl, battle.fi & battle.fs from FINAL FANTASY VIII\Data\lang-en\ to the folder above: FINAL FANTASY VIII\Data\
2. Do everything what's in hardcore's readme.
3. Copy files again to FINAL FANTASY VIII\Data\lang-en\ (overwrite).
This is a message straight from colly himself about getting this to work with ff8 steam. Though I have been unlucky as with a fresh install and only using this method get an error preventing from the game starting. Can't remember the error but will make an update when I attempt this again which will be soon.
