does that have anything to do with rpcs3? , is psp a lighter version of ps3 (HW wise)?
Ah, no. What happened is that inside the PS3 and the PS Vita, Sony created a PSP emulator (that's how it can play MINIS and Remasters).
By analyzing the PS3 code associated with this emulator it was possible to extract new keys, which will also be important for rpcs3 in the future.
The PS Vita key was published by Total-Noob after the new firmware upgrade blocked TN-V.
Hardware wise, PSP is completely different from the PS3 and from the PS Vita. For example, their CPUs are all based on different architectures (MIPS for the PSP, ARM v7 for the PS Vita and PPU/SPU for the PS3).
