The power-up for Assault styles are really useful. It changes the character's specials. E.g. Kaixa's blaygun attack are replaced with extra slashes, Garren's Upper Fire is changed to Burning Smash as well, so if you're close to opponent it provides more accuracy.
For tag, some explanation:
Pressing left or right on D-pad switches characters, costs no gauge.
Pressing down, both characters appears on screen, drains gauge, you are in charge of 2nd character, when gauge goes to zero 1st character disappears.
Pressing up, both character appears on screen, drains gauge, you control BOTH characters, but 2nd character responds first. When gague goes to zero 2nd character disappears.
So in order to achieve Double Breast Cannon, summon either Proto-Birth or Birth using up on D-Pad, then press Z on nunchuk twice.
I'll be very quick then.
1- Take your song, edit it at will.
2- Convert it to .brstm format, there are a lot of programs that do that, try to find one that you like and that you are able to edit the looping. (I recommend BCSM_GUI but if you want to be quick and do not want to edit just use Androu1's BRSTM Making Tool )
3- Replace the old .brstm by the ones you have created using WiiScrubber. (Make sure that the file sizes are +/- the same as the original, it is not important but it will run smoothly)
4- Burn the new ISO and voila.
PS: Some errors may occur so be ready to use A LOT of DVDs until you get it right,
Thanks for your explanation. I am using an emulator so I suppose I can ignore step 4. However I'm not too sure about step 3, what is WiiScrubber? Also how do you open iso files, it always appear as a winzip file, and when I open it there's nothing inside it.
