This kind of problem isn't related to an unemulated opcode : Satourne has all the opcodes fully emulated.
This is typically happening when the game jumps to an unpopulated memory area, the slave sh2 tries to execute some code that isn't there yet, resulting in the unknown opcode problem.
The SCU message refers to a register that shouldn't be written (according to the doc) and that was written anyway. It doesn't impact things, it's just a control.
