sm-3ds

<!--  -->

This is a 3DS port of Super Metroid, based on the PC port by snesrev.

This runs at about 50fps on hardware per my testing. If you switch to the backup SNES emulation mode this gets back to 60, but audio will not work. And where's the fun in that anyways? With some careful optimization, this could surely hit 60fps.

Saves are dubious right now, I have them working in emulation but not on hardware. They should be stored in the SD card's saves directory.
