What's the problem? Describe what went wrong.

When trying to use certain Gecko cheats in Metroid Other M, such as third-person Missiles when holding the B button, the cheat doesn't work. It either does nothing at all, only fires missiles despite not holding the B button, or intermittently fires missiles when not holding B and being able to fire missiles when depleted (the code doesn't allow this). Other cheats, such as walk through walls while holding B or Samus color-changing codes, sometimes doesn't work as well.

JITIL just hangs at boot when any code is loaded.

All codes work on the Interpreter though and on a real console.

What steps will reproduce the problem?

Downloaded codes from WiiRD database, checked the third-person missile cheat in the Game INI menu.
Started the game, loaded a save, held the B button and Samus fires her beam instead of a Missile.

Which versions of Dolphin did you test on? Does using an older version of Dolphin solve your issue? If yes, which versions of Dolphin used to work?

5.0-1424. The codes work on the interpreter, but not JIT or JITIL (JITIL just hangs on boot). Tested JIT on 5.0-9 and 4.0-7840 and the codes don't work on those either.

What are your PC specifications? (CPU, GPU, Operating System, more)

i7-4770K @ 4.2ghz
16GB DDR3-1600 RAM
3GB Nvidia GeForce GTX 780
Windows 10 Pro x64 1607 (Anniversary Update)

Is there any other relevant information? (e.g. logs, screenshots,
configuration files)

Here's the Gecko code for third-person Missiles (Hold B to use Missiles):

This is likely due to core timing being more accurate in interpreter.

IF that is true, then you have a choice. Performance, or accuracy.

Regardless we should try to fix this :P

Our Gecko Code handling is terrible and stuff. This may not be a CPU Core issue after all. Merging this into a global issue.
