Lo-Fi Games

I've tried all the different options, and they all sound the same. "thwip" like the Junkbow. I wanted to try to change an item to use the Harpoon Turret sound, which seems to be an option in the list (SHTHOOM) but the setting isn't being honored. After multiple tests with each setting, it's always the exact same little "thwip" sound when firing.

Am I missing a setting somewhere else that needs to also be used so that this selection box works?

After zooming in to a lot of ranged combat.... I'm pretty sure this is broken on the Spring Bat as well. Looks like it's supposed to have its own, unique sound, not used by anything else.... but all i hear is the same "thwip"
