Monster Hunter Portable 3rd

[flaminglambchops]

Hi, I was wondering if there is a way to play the normal non-HD version of Monster Hunter Portable 3rd on a PC. I've tried the HD version but it keeps stuttering in framerate and is almost unplayable, this is even after tampering with the graphics options and setting them to the lowest possible. Freedom Unite runs perfectly fine on my rig so I was wondering if I could get the same results with the non-HD version of Portable 3rd.
