In theory, you should be able to decrypt SPRX files with PSPCipher. Try editing a SPRX file with an hex editor and you will see two headers: PSPEDAT (used for EDAT encryption) and ~PSP (used for PRX encryption, should be at offset 0x90).
Remove the PSPEDAT header and try decrypting it. I'm not sure if this method works for all SPRX files (there could be an extra encryption layer after processing the PRX), but I've already tested a few that worked.
I'll add the ability to load decrypted SPRX files externally so this can be properly tested.

I've fixed the PRX program header relocation type 0x700000A1 in r3440 (I believe this game uses it for SPRX). Could your friend test it again please? Thanks!

Ahh, thanks. It appears this ELF file is missing one field of the section header. I'll have to add an extra check to ignore this case.
