Description
frsqrte (Floating Reciprocal Square Root Estimate) Instruction is handled improperly by dolphin. Enabling VERY_ACCURATE_FP in source code mitigates a lot of these issues, but causes other issues in the process. JITIL seems to avoid most of these issues completely, while doing better than both JIT and Interpreter in cases where it is affected.
This leads to physics errors, hangs, and other nasty bugs that impact playability.

Adding the main issues I found with this. Twilight Princess is another candidate, but, it apparently needs other things too in order to work.
