Not particularly. PCSG00958 should have no sce_pfs inside it, and if copying the archive.psarc to a different folder then copying that copy onto your PC didn't work, try FTP.
Your message to me sounds like you opened PCSG00945 first before decrypting. Before you open the folder, hit triangle then open decrypted. you'll know if you did it correct if sce_pfs isn't present on screen as a folder. I just did my own steps...
Year later, let's make another update, why not?
Anyways this is v1.02 with some bugfixes:
- Fixed Media Player choices.
- Fixed symbols in key list.
- Re-converted movies to fix cropping issues.
- Fixed an incorrect jump copied from the switch...
