ever since the first ps3 jb was out i was hoping for a region patcher so i can watch all the blu ray discs i own no matter if region a/b/c and nobody ever knew how...
after lotsa research and checking around i present to you 3 patch*.txt files for lv2 patcher!
just copy the files into: /dev_hdd0/game/LV2000000/USRDIR
and the next time you start lv2 patcher you will have 3 new patches to choose from (region a/b/c)
once you patch you don't have to restart your ps3, it works right away! if you restart your ps3 the bd region is set to standard again
tested & working for me on pal cechcxx machine with 3.55cfw (rebug & kmeaw) using kmeaw's lv2 patcher v9!
this only works for blu ray and nothing else, for dvd the old xregistry trick applies...
i didn't code anything, just collected and tested, sources for this can be found here:
