Ok, I know that at this time this thing is heavily searched, mostly by noobs (like me). So I found here in PSX-PLACE, this tool called PS3 PKG Ripper (by @Rudi Rastelli). This tool is super easy to operate, but don't have a fast way to extract multiple PKG, what was sad. BUT... the creator was so mercifull that provided a way to choose the output. With this in mind, I created a batch file that reads all PKG from folder and extract (merging) them. Instructions 1. Download the work folder HERE; 2. Unzip it; 3. Put your PKG files into PKG folder; 4. Execute RIPThemAll.bat; 5. Get your extracted content in Output folder. I know, this is simple, and anyone could do it, but nobody did before, so I decided to post here. Hope that next versions of original one have this simple task on GUI, but this depends on creator. If you missed HERE IT IS THE DOWNLOAD LINK.
