Sorry if this has been discussed before, but a quick search didn't turn up anything. Has anyone else noticed a metallic-sounding "twang" when playing a game under Zsnexbox? It's like a faint echo, as if the game's sound was reverberating inside a tin can. It happens in every game I play, but is very noticeable in SFII Turbo, where you really hear it in every thwack, and in F-Zero, it painfully distorts the hum of the cars; they sound like a swarm of mosiquitos

I thought it could be my tv, but tweaking all of its sound options didn't change a thing; besides, I don't notice it in anything else I play on that set, emu or otherwise. I also messed around with all of Zsnexbox's many sound settings, again, to no avail. Is this just a product of the way Zsnexbox renders the Super NES's sound chip? Or am I going crazy?
Think I'm going to give 9x a try to see if I notice it there; just wondering if anyone else has experienced this.
