no decryption.

Now that just sounds a little funny, since we know you cannot execute anything on the PS3? (other than using the swap technique)
Care to elaborate on how you accomplished this mean feat? :-)

Portions of the file are both compressed and encrypted. The compression of the file will make legitimate values in the ELF header to appear wrong (out of bounds.) If you look at the qword at 0x0018 you'll find what appears to be the file size before signing, compression, encryption, etc. This value...

I am "totally" speculating that it could be a round-the-file-and-back wrap around offset. So if the file is 100 bytes, but the offset is 250 bytes, it literally means "go around the file twice and then 50 some more bytes". Is there anyone who has coded on the PPC64 platform to co...

Seeing as the core processor is a PPC, it probably runs in big-endian mode. Make sure you aren't trying to read addresses in little-endian mode. I believe the ELF header is endian-unaware? So, when we talk about the Section Header offset, which is supposed to be 8 words (since this is a 64 bit arch...

"otheros.self" is not a Linux program. It runs under the Game OS and as such it's most likely encrypted and signed by Sony. The majority of the file looks this way (high entropy, uncompressable). I would agree that there is some encryption, but if you take the "SCE" signed first...

I have been playing with the "otheros.self" file and have pretty much have figured out that the initial few bytes contain the Sony Computer Entertainment magic word "SCE". After that comes the standard-looking "0x7F-ELF" magic bytes. I tried to decode the ELF header por...

For what it is worth, I had to send this letter to IGN after getting disgusted with their editorial: <BEGIN LETTER> I am shocked and utterly disappointed in your comments about the PSP Homebrew crowd and their efforts to run legitimate applications on their own machines, that THEY PAYED for. Your at...
