Use this tool to view, create, and generate PS3 Themes in realtime. No need to go through tedious XML files or 100's of menus to create/edit your theme. This tool is a WYSIWYG tool by just pointing and clicking to change theme icons with drag-n-drop functionality.
Note: Some users are having issues running p3t compiler through the application. The problem is with the installer. The author states he will update the installer to fix that problem, but for now do the following if you can't generate the .p3t file:
Copy the 'PS3 Theme Creator' folder from 'Program Files' to the root level (e.g. C:). Rename the 'PS3 Theme Folder' to 'PS3ThemeCreator' (no spaces). This should resolve the p3t file generation on some machines.
Steps to extract a .p3t file:
1. Copy .p3t file to 'PS3ThemeCreatorexternp3tcompiler' folder
2. Select 'File->Extract P3T File' menu
3. Select the .p3t file from 'PS3ThemeCreatorexternp3tcompiler' folder
You should now have a new folder 'extracted' under 'PS3ThemeCreatorexternp3tcompiler'
