Hi, sorry for my bad english (i'm italian :P).
i would to present to this wonderfull community my last creation (or, better, "modification" :)).
3.73 Dark_Alex PopsLoader
Download of the package from HERE
It's a modded version of the 3.71 Dark_Alex PopsLoader that allows to load prxs of the new Sony Firmware 3.73.
3.73 pops will take the place of 3.72 pops.
N.B.: This is "only" a modified version of the original Dark_Alex's PopsLoader, so all rights and merits belong to him!
The same of original POPSLoader.
To obtain 3.73 prxs you can use RSPsar Dumper (or M33Psar Dumper).
PRXs must be decrypted, so you need to use SQUARE option in Psar Dumper.
Necessary PRXs are the same of 3.72 pops, so: popsman.prx, pops.prx, libpspvmc.prx e pafmini.prx.
Later you need to insert PRXs in /SEPLUGINS/POPSLOADER as popsman373.prx, pops373.prx, libpspvmc373.prx e pafmini373.prx.
At the end you need to overwrite original PopsLoader.prx with the one contained in the package.
To Dark_Alex, the only POPSLoader inventor and creator!
