For those unaware, SCETool is a PS3 key crypto tool that supports a wide range of binary file types (SELF, RVK, PKG, SPP, OTHER).
To quote via Twitter: SCETool 0.2.8 (intermediate release)
Version 0.2.8 (intermediate release):
Fixed minor bugs where scetool would crash.
Added SPP parsing.
Decrypting RVK/SPP will now write header+data to file.

seems like naehrwert found that hes SELFs are working on 3.56. And are working on a update of scetool yet again (0.1.1 doesent make valids - twitter.com/#!/naehrwert/status/153570111750545408)
no it seems 3.56 doesn't check for it, only 3.56+
But not generated by version 0.1.1, I'll release a fixed one soon!
apparently NPDRM SELFs generated by scetool DO work on 3.56 lol
