A bit more detail to ArrozCamil's comment. If you put in the name unclepeanuts in lower caps and with no space when you start a new game, you get 5 mil, unlock all C, S, and R class cars, all parts are available for purchase, and All Tourneys are complete. Although this sounds dumb and kinda obvious to say, this is essentially just a sandbox mode, but without selecting Arcade Mode. Hopefully, this helps out on understanding a little bit more about the unclepeanuts thing. Oh, and for Hydro, that Max Wager List is absolutely helpful :D
