Killzone Liberation

[LunaMoo]

I'm not familiar with this game to say for sure, but if the update get's decrypted on real psp then depending what it exactly is either simply patching iso with it or implementing some feature to replace the files with their decrypted version instead of just failing to decrypt would likely make it run on emulator.

However by just using emulator itself without real hardware - no. 128bit AES is not a joke.
