I didn't. Or not aware. I went like this...
From the OP i understand this is a standalone, so i don't need anything from the original game/post. Downloaded the mod, extracted, replaced the two files with the ones from 1.1b.zip, started a new game (had not played before anyway).
Then i played mostly following the green text, but not always, especially as the game progressed. Reached some red text here and there, which i guess is finished "story" with no more new options/scenes. Got Ann's questline, unlocked Level2 and i think 1 or 2 scenes at the pool, that's all, then had to go for other options, since it started to crash when Checking the pool.
As for the cheats i didn't even find that option. WT in OP says it's there, don't know where, even tried shift+o for console.
