No difference in terms of content. Both versions have all the modes.
Wireless Play
PSP version uses ad-hoc. 3DS version uses local play. These are just different names for the same thing. Both versions support two to four players, with two players fighting and two watching. The PSP version will work with Ad-Hoc Party on PS3.
Other Wireless Stuff
When playing between PSP-1000, PSP-2000 and PSP-3000, the PSP-1000 may sometimes skip frames. In terms of command timing, there's no difference between the PSP and 3DS versions.
For the PSP version, the Japanese and overseas region versions cannot play wireless against one another.
Save Data
Both versions can have one save data file. 3DS saves to the save space on its cards. PSP saves to Memory Stick, requiring 288 KB.
3DS Special Features
The 3DS version has these special features:
Outside of movie scenes, the game works with 3D output. You can lower the 3D volume all the way to make the game 2D, of course.
The lower screen shows a command list. This isn't for shortcut commands though. You can't tap the bottom screen to perform special moves.
PSP Special Features
The PSP version is compatible with data install. A 600 megabyte install will speed up load times.
