A program can tell that it's running on Mesen because the buttons always change right at vblank.

To reproduce:

Install Mesen 0.9.8
Start the attached test ROM "Telling LYs?" telling-lys-0.01.zip
Press all 8 buttons in any order
Watch the arrow sprite at the right side

Expect: Arrow moves after each press, followed by "Pass", as on my NES

Actual: Arrow stays at top of the screen, followed by an "Incorrect behavior" message that clearly isn't "Pass"
