This is probably why Nintendo added this argument in the first place! I always felt it was strange that this argument existed when most of the other arguments are related to save states, volume, or filters. I'm also confident that the Preset IDs for Yoshi's Island and Star Fox 2, both of which are Super-FX-2, set the -boost-fx argument to 2, in order to properly emulate 21.4 MHz. I'm confident in my belief that Canoe emulates the Super-FX at a clock speed of 10.7 MHz, in order to properly emulate Star Fox. The GSU-1 and GSU-2 did not contain this internal clock speed divider, but instead used a register to flag the Super-FX operating frequency. The MARIO-CHIP contained an internal clock speed divider which halved the clock speed to 10.7 MHz. We also know that the GSU-1 (later revisions) and GSU-2 (Super-FX-2) are capable of running at a clock speed of 21.4 MHz. We know that Star Fox uses the MARIO-CHIP-1, an early version of the GSU-1 (Super-FX-1). *Technical information ahead! Turn back now!* I went ahead and looked into it a tiny bit.

I've been getting better and better at the game, or at least I think I have anyways.
