As I expected, it's just a mess of sprites. He's not coptering while shooting up. That first one is actually the shooting up while on vine sprite.

I can't believe you actually thought that. There is no copter ears displayed above his head nor actual ammo coming out (I know he's using copter ears, but like I said the sprites are bugged), and all other sprites displayed were incorrect, so what would make the first one correct?

I put the macros from 1.23 into my TSF. EDIT: It happens in vanilla TSF (and maybe in older versions of plus), but the sprites are displayed correctly in TSF plus (or 5.0, at least).
