Yeah, my friend doesn't have a USB hard drive though.
I guess I should also be clear -- I actually replaced a character with a PSP character, as I just wanted to see if they were done. He (Hawkeye) worked fine as near as I can tell.
It looks like the Wii uses what I'd call 'psuedo-motion'. What I mean by that is the motions are basically the equivalent of button presses. And the whole reason I mention that is that the powerstyle and talent files aren't any different. That basically means that if you want to execute an Xtreme, you do it the same way for every character. So there's no writing custom stuff in powerstyles and talent files for Wii controls. The Wii just translates the button presses you'd do on any other version into motion controls. Basically what that means is that other, totally separate mods might be possible. The Wii uses Alchemy 3.5, so I know it can use animations from the PS2/Xbox. Skins, textures and effects can be stolen from the GameCube XML games as it's the same format, but I dunno if PS2 models and textures (specifically the textures) will work until I get time to try new tests. I've also contacted Winstrol about coming back to update ZSM Editor to work for GCADPCM (GameCube/Wii) and the PS2/PSP sound formats, as I have the sound formats figured out, I just need a program to manipulate them.
In all of this the Xbox mod is still my priority, and I don't have tons of time to work on that with a steady job, wife, baby and a new house. So for this mod I'm just gonna have to put a "When it's done/If it gets done" time frame on it.
Incidentally, if anyone already has a modded Wii and knows how to use Trucha to replace files this would go a lot faster, as I could create a test version of some files, then send them to someone to test.
