I think SDK is tighly coupled to the Games i.e. Games are dependent more on the SDK used to Code them rather than the Firmware Version ,which cane be manipulated from the ParamSFO/watever File. Thats the reason why new games which dont use the 3.4 SDK wont work even though we change the ParamSFO/watever file to point to 3.41 in the required version. This isnt related to the Downgrade but the JB for 3.5 i suppose
I am not sure of this though :ashamed:
The games are dependent on the SDK. Newer games don't work because they are looking for libraries present in the 3.50 SDK. Those specific libraries are just not present on the old firmware and so the games can't run.
