Managunz (optionally) can patch explore_plugin.sprx and libfs.sprx if you enable this options it makes a copy of the original files ---> to managunz installation path, then the copy of the files are patched and renamed
Since that point the patched .sprx files stays as part of the managunz installation files, and incase you use that options to patch them again later (with different games) then managunz uses the files that are already patched
So... in some way is patching them "on the fly" too (but it does it only 1 time), and the originals are not modifyed
Not sure if this features related with patched explore_plugin.sprx and libfs.sprx works, we was thinking incase are broken maybe is because the resigning type... but doesnt looks like
Another thing that could be related with the resisgning type is... in the "Create shorcut PKG" it needs to resign an EBOOT.BIN (and build a PKG with it inside). Both looks fine, the PKG is debug as far i remember, and the EBOOT is resigned with the 4.21 keys... but dunno... if you can take a look at this
@Joonie it could be handy just to verify there is no problem with that resignings
