i wanted to inject or just replace some wav files inside .xwb soundbanks, is that possible?

i used EkszBox-ABX and swapped the files, but it doesn't work, it always keeps the original sound....

can someone help?

he had quite a few versions, were you using the last one?

Did a lot of ripping and downsampling stuff myself in the past, with the same tool your using. However altering the containers was a bad thing in quite a few cases as certain games required your modified file to be exactly the same size as the original container. It can sometimes be down to just a few bytes difference but certain tunes or background music wont play, in more extreme circumstances the game wont boot. So i gave up after a few games i tried.
