If you've extracted a str2_pc file and made changes, you will need to repack it before you can see your changes in game. To repack a str2_pc file, follow this guide! You will need: My Saints Row IV tools: http://www.saintsrowmods.com/forum/threads/minimauls-saints-row-iv-tools.3188/ Files to repack - these should be in their own folder with no other files The appropriate asm_pc file for your str2_pc file. A folder to place the finished files in. I called mine "output". To repack your str2_pc file and update the asm_pc file, follow the following steps: Download the latest attached file from the Saints Row IV tools thread, and extract it using your favourite extractor.

The following window should pop up: We will first select the files we want to pack - click the Browse button next to Source files. A window will pop up allowing you to pick the folder containing your source files: In my example, my source files are at D:\Gaming\Saints Row 4\modded\cell_cheats.str2_pc. Select your folder and click OK. The asm_pc file for my example is "vint_doc_containers.asm_pc". Look up the appropriate asm_pc file for your str2_pc file and copy it to your "output" folder. Now click the Browse button next to Update asm_pc file?. A file browser will pop up: Browse to your asm_pc file and select it. Then click Open. Your main Packfile Builder window should now look something like this: When you are ready, click the Build button. A save window will pop up asking where you want to save your new str2_pc file to: It is important that you get the file name correct - it should be exactly the same as the original str2_pc file - if you do not then the builder will be unable to update the asm_pc file correctly. When you are ready, click Save. Most str2_pc files will build in a matter of seconds. You may see some progress messages flash up but once finished you should see a window like the following: Your str2_pc file has been built successfully and should now be in the folder where you saved it. My output folder now looks like this: Copy your new str2_pc file and your updated asm_pc file to your Saints Row IV folder - the folder containing SaintsRowIV.exe - and start the game - you're done!
