02f76633 00060c63...
There are two cases which will trigger this unexpected exception:
1. The instruction at PC = 0x80000068 is not implemented.
2. Something is implemented incorrectly.
Find this PC(0x80000068) in the disassembling result to distinguish which case it is.
If it is the first case, see

for more details.
If it is the second case, remember:
* The machine is always right!
* Every line of untested code is always wrong!
