is memealign required?

Helle,

when i read source code of different applications (like fs toolbox or others like that), i see that when we pass an objet to an ISFS function, we always initiate the memory with a memalign(32, xxx).

Is it really required (i think of ISFS_GetFileStats, ISFS_Read ...) ?

Probably - the Wii requires certain memory be 32 byte aligned. If it's not...it can lead to unpredictable results.

Does the PowerPC CPU require memory to be aligned?

I've some response :)

Generally, yes we need to be 32 bit aligned (for exemple, Get_FileStats make a DSI Exception). I've made some tests and i often have e DSI Exception when the buffer isn't 32 bit aligned.

Except, that's not the alignment exception.

Yes :) But this exception occures because we don't align buffer (i think, the underlying function write elements over the end of buffer, wich create after the DSI Exception)
