Welcome to MARP!(posted 9956 days ago)If you already have a score for a game and you get a score that beats that, feel free to re-submit. The script will only store the highest score per player, so you won't place twice.
As for dip switches... I guess using TG Settings is preferrable if that game is actually on the list, but I always use default settings. I suppose if someone has a high score that's on TG Settings, it's ok to knock it off (if you can) using TG settings too. :)
