In the rules it states that "All runs must start from a fresh file". Back when I was mod this just meant starting from the beginning of the Super Mario Challenge. my previous WR has been rejected due to these conditions and I haven't found a way to erase all the medals and player statistics without making/using a new Nintendo ID account and then installing the game again. If anyone knows how or if R0main could clarify, that would fantastic.
Yeah someone wanted that but isn't possible at all and I forget to reedit rules again and put your run again on the boards. My apologies.
