When attempting to run Metal Gear Solid 3, the emulator quickly crashes on patch_fs as MGS3 uses an unimplemented code.

VEX_Vmovups_ymm_ymmm256 - With a hacky implementation of patching ymm0 with NOP, it seems to progress to the point other games hit with DMEM

With kernel-mode kernel we don't need to do any patching so this will automatically fixed.
