that's the version i have used for Rogero 7.9a ,which is still till this minute un-changed on Kmeaw's Github here:
https://github.com/kmeaw/lv2patcher
then rogero v7.9a have the LV2_patcher V4 as u name it...
which have the new patching functions with some patches disabled to avoid crashing, it also have the main.c file structure all rewritten to use a different method to read and load the payload.
Currently i am experimenting with some hybrid code of the patcher hoping to have better results...and i think the older/initial release of the lv2_patcher was more stable.
anyway this will take some time+lot of testing to get it stable enough
N.B: on startup,the manager will try to load the payload into memory, in case it fails, it will show "Unknown Payload" on the bottom right corner of GUI, so you must restart the PS3 and restart all over to have it loaded right and showing as "PL3/Kakaroto" on the GUI.
Also if you have loaded lv2.pkg manually before running the manager, it will detect it on startup and won't try to load the payload again, instead it uses the one already loaded...
