It is important that when scanning Dolphin's memory that we only look at Mapped memory. 
The mapped memory corresponds to dolphins emulated memory and from just simple observation,
the first Game ID address found in the mapped memory region is the start of our emulated ram.
This could be completely wrong however and it might break at some point as a result of this
assumption. 

What's is most important is that we have Cheat Engine scan settings only search emulated memory 
or else this will fail. You can do this in Settings > Scan settings > uncheck both MEM_PRIVATE 
and MEM_IMAGE at the bottom. Then finally, of the three make sure the only checked box is 
MEM_MAPPED and that should work.
