I have a quick question for anyone willing to field it: I'm pondering ways to distribute signed pkg files to a ps3, and I'm wondering if you could use the PSN Download Manager/booster, and send the signed file over to the psn in lieu of the actual demo or game downloaded.
I assume it hashes the file for an md5 sum or something to prevent this. However if not it may be a fairly simple way to get signed homebrew on a legit system.
edit: tried it. Got an 80029564 error. Damn. As a followup, I'm reading from Kakarotoks that geohot's signing tools are incomplete and don't actually sign the pkg itself, only the self files. which would explain the failure I am experiencing trying to get the ps3 to accept an unsigned pkg. His close sourced MFW apparently patches out the PKG check.

hum... can someone help?
ok, i got the geohot sign tool (make_self_npdrm.exe) but i don't think i understand it right... tried resign the gt5 eboot.elf (that i did unself with fail0verflow tool) running like this
make_self_npdrm EBOOT.ELF EBOOT.BIN UP0001-BCUS98114_00-HOMEBREW00000001
but it doesn't show anything, it seems that the tool isn't not even working since it doesn't even show any errors for me

Make sure you have the right DLL files and the elf is in the correct format.

well, the dlls i have:
and the elf i got from using unself.exe tool from fail0verflow. thing is, i can sign an eboot.bin with the fail0verflow makeself, however it seems invalid since the file is 4kb bigger than the original eboot.bin and if i try sceverify it says:
perror: No error
using WinXP sp3 here, dunno if it makes any difference.

Its a lot more involved than that and if you really must backup GT5 (the one game actually worth paying for btw) then download PSL1GHT SDK and compile your own homebrew application first.
Then you might be able to make the leap to figure out how to re-package your $ony material as your own NPDRM material...
Only way your windows box will work is if its running a linux vm btw...

i got it working, it was because of the old version of some dlls
to be more precise... now it signed fine... but i still don't understand why fail0verflow makeself adds a useless header into the file.

would spend more time on reversing the npdrm keys. geohot did it also. anyone know / can imagine how he did so?
