I tried, but it didn't work.
It's possible to extract a pkg content, so it should be possible to launch it via the fat32device:/HOMEBREW/pongus/EBOOT.BIN
I unpacked the pkg (using
PS3 GUI Toolbox).
Inside, there were :
HBRW00001/ICON0.PNG
HBRW00001/PARAM.SFO
HBRW00001/USRDIR/EBOOT.BIN
Then, I put the file in USB:/HOMEBREW/pongus/EBOOT.BIN
Using Hermes v4 + Open Manager 1.16, pushing Start to see the homebrew list.
Pongus appears, but when I select the launch command, it doesn't work and go back to XMB.
PS3 GUI Toolbox can also decrypt eboot.bin into eboot.elf file
So I tried to decrypt the eboot and rename it to eboot.bin (.elf are not listed by Open Manager), but it didn't work either.
Maybe it needs the param.sfo to boot ?
Or maybe they have to be compiled in a different way ?
Or, the extractor corrupted the file ?
I think homebrew should be released in form of a .bin too, and not only as an installable package.
Note the gameID : homebrew 00001. Developers should maintain a homebrew database to know which gameID is already used or available to prevent overwriting.
