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.
