while some things in the GBA version of SMA2-SMW seem to be worse, other few things were made BETTER such as game saving
In SMA2 for GBA, I can save my game ANYTIME
, EVEN on the overworld map
AND while playing a level
by pressing START. Also beating Bowser in his castle after the ending scenes also allow the game to be saved. No need to clear just switch palaces, ghost houses, fortresses, castles and certain Special levels just to save the game. the Save options in SMA2 are like SMAS for SNES [Continue, Save & Continue, Save & Quit]
Can't do that yet with current version of SMW Advanced hack but I'll give it a full playthrough anyway.
also on SMA2, fire mario & cape mario turn back to super mario when hit by an enemy or spikes.
