When unpacking a game and wishing to repack once some mods were carried out, I found that there are errors in gengp4_app.exe.
When generating gp4 files for application packages, this was setting the following:
<volume_type>pkg_ps4_patch</volume_type>
storage_type="digital25"
Also param.sfo was being modded to be a type gp package.
The modded gengp4_app.exe changes the gp4 file to create:
<volume_type>pkg_ps4_app</volume_type>
storage_type="digital50"
Leaves the param.sfo as type gd.
I have linked a zip file that contains the exe's for generating patches and for generating game packages (the only modded file is the app one as the patch one was working fine, (although you should note that one mods your param.sfo file when creating a gp4 file)
