If you want to TAS Super Punch-Out!! but with NTSC mode set, here is my recommendation. You need to use the J version because the Referee Mario(?) count when the "Opponent" & the player (which is Little Mac LOL!) gets knockdown is faster than the US version.

The Europe version of the game has a faster timer because of the PAL system (I think)
