Emulator

This doesn't tell us much. I really wish people wouldn't deviate from the standard issue template unless they fully explain the problem otherwise. Mainly, I'm talking about the part that says "What do you expect to see? What do you see instead?" or with the new template "What's the problem?". You only say it's broken. How is it broken? I am away from home and can't test or check it.

Sorry,I thought this would be clear.
I mean broken like the function is doing nothing.

What do you expect to see?
When I turn on "EFB Copy Regions", I expect to see the EFB copy regions.

What do you see instead?
Instead I see nothing, normaly this function shows me the EFB copy regions,
but now it doesn´t show anything. There is no difference when the function
on or off.

I have used Metroid Prime to test the function, like I always do.
In the moment I have no time to track down the rev that broke it.
