Unity3D Engine *.assets extractor
Couldn't find an extractor anywhere, so I wrote my own. :) Long overdue but wasn't motivated enough to go through the pain of the format. ;)
If you experience any problems, pm me and I'll take a look. The outsorted file types are only the ones I found.
Else, if anyone can identify some of the missing extensions, I'd be grateful!
lateste updates:
- if type 49 contains png or xml, it is recognized and the size adjusted
- included variant with file tale at the end (some resources.assets use those)
- mp3 detection included
