There's some minor issues on SSBM (maybe that happens on another game):
-Loading are a little bit "slower"
-Entering Select Character/Select Stage controller lags at the beginning
-Freezes not often anymore, but freezes once of many times on "Now loading" or loading menus, select character, select stage, event match, classic, adventure, intro, cutscenes, etc; and all of this, SSBM are playable 93% (compared to old(est) revisions)
-MCEmu shall be fixed (at the moment there's no worries 'cause i could use kenobiwin [SD:/sneek/kenobiwin.bin to load cheats] (in my case i'm loading debug menu)
-and PS3 controller SUCKS! I rather Gamecube controller overall to play SSBM SERIOUSLY!!!!
