We're not supposed to openly discuss this because of one of the files that comes with that patcher.
I will admit, though, that I've been using it for years now (and yes, I own a LEGIT COPY of TSL) and that it works beautifully, though the HUD gets stretched and fugly. I didn't know about having to set the resolution to 800x600 with swconfig first, though. I'll have to try that the next time I install the game.
