If you change the start.dol (the main executable) or alter character action states, your ISO will no longer function on standard Slippi netplay. You will need to keep a "Vanilla 102" copy for ranked queuing and a separate "Modded 102" copy for solo training or friendlies with matching mods.

Version 1.02 is preferred because it is the most stable and bug-free version of the original game. Earlier versions (1.00 and 1.01) contained several glitches that could cause the game to freeze or behave inconsistently.
