Super Mario Galaxy 1 &2 Slowdown

[catabarez]

I'm having trouble running these games in full speed. They were running just fine the other day but after I attempted to use some custom textures the game slowed down. I deleted the textures but that did nothing. I am using these settings right now:

- idle skipping : on
- frame limit : 60
-JIT recompiler
Lock threads to core : off
force console as NTSJ : off

Audio :
-DSP HLE emulation : on (note that music will stop after a few minutes of playing, this a very knowing issue in SMG and there is no fix for it right now)
- Enable DTK music : off
- DSP LLE on threads : off
- Dump Audio : off
-Audio Backend : DSound
-Sample Rate : 48000
