damn, alright, i'll try cup game again.
EDIT: Okay, so i went through the game again to take screenshots of the locations, and i discovered a 3rd $20 note. Totally to $63 in the first couple in-game hours.
EDIT 2: Okay, so after i actually got the VHS tape, i found out that you can't do anything more after that, due to needing to go to the computer class in school, which has yet to be added into the game, so there's no reward for finding $50 and paying for the tape yet.
