After being inactive for a while because I had a problem, finally i finished to create and fix my personal tools for PKG/SPKG
![]()
ONLY FOR CFW
This tools are based on failoverflow's tools, but with support for spkg files on CFW 4.XX, for for example, install a PUP directly from XMB or avoid to do a downgrade to 3.55 to install
A spkg file contains header/metadata for that pkg who has his name, PS3 on +3.56 checks his header/metadata for matching, if not fails and can't install
On FW 3.55 and below is not necessary that spkg files
Minimum Requirements
Features
spkg.exe
unspkg.exe
new_pkg.exe
new_unpkg.exe
Thanks to Team failoverflow for the initial tools
Thanks to Abkarino
Thanks to Rogero, samkorg and santi1403 for test the tools ;)
