Also, screw it, the exploit is that the game doesn't make you earn any money for buying the movie for Emily. Please fix the time-skip glitch because I would like to be able to make this walkthrough perfect. I'm pretty sure I can get all 6 girls if I just sink a few more hours into trial and error... :(
I swear to god if you ruin this for me and don't bother to fix your crap...
