Tested the Wiz version and it is working great. Super Metroid is stable at 800MHz with fast/fast, and launched via GMenu2X using its tweaked RAM timings option. FPS drops to 40ish in Super Metroid when transparency effects are active (yellow scanning beam from eye scanners), which is an improvement from the 35 or so FPS that I got before.
Wolfenstein 3-D did lock up after a few seconds with the same settings, but that was just a test so it's not important to me.
