Using N64 cheats forces 1 fps interpreter mode

[Tasoulios]

Whenever i enable a gekko code on any N64 game, Dolphin goes unresponsively slow to the point i can't even exit it (i use task manager to kill the process). On the top of the window it says "interpreter" for some reason too. If i uncheck the cheats it's all normal again.

Are N64 cheats unusable with Dolphin or there's something wrong with this particular version (5.0-691)? I can't find completed saves anywhere so i thought the last chance would be using cheats for fast completion...
