Install them both just to be sure, since most of Brawlbox was coded running 3.5.

Didn't work.. with or without SP1..
Do you have any clue on what the problem can come from ?
It's not the brstm itself since it does this for every brstm.

Thought 'classic' brstm with 2 channels works perfectly fine.. for the others, it gets loaded since the UI display the number of channels, loop point and so on, yet it crashes right after :/

Does it require any specific Framework ?
I think I have the v4.0 installed; maybe i need to install the 3.5 ?

Just open it in Brawlbox lol

I get this when I try:

System.ArgumentException: La valeur n'est pas comprise dans la plage attendue.

I'm sorry if this was already asked again and again, but seeking through 460 pages wasn't encouraging at all x)

Is there a way to open Multi-channel BRSTM files through BrawlBox under Windows 7 (x86) ?

Thanks :/
