Jump Tables Guide Skate 3

[Roigo21]

Hey guys, im new to reverse engineering. So, as the title says, I will try to at least get Skate 3 decompiled, but the XenonAnalyser is unable to find the jump tables. So i started looking through the default.xex file and found a pattern that appears through all the code (it looks to be the only one there). Tried to adapt it in the C++ code but the constant PPC_INST_SLWI doesnt exists there (only SLW), so no output still.

the part that repeats is after the cmplwi.
If anybody wants to join me in this journey, i would be very appreciated, since skate 3 is a great title to be playing 60fps+
