It's how the SNES works, unfortunatelly. Especially careless designers tend to put too many sprites on-screen and so the SNES can't finish the frame before it has to render. Certain codes also are quite slow (most famously NMSTL which gives you more free sprite tiles but at a rather huge performance cost) and some others use SA-1 (external chip but complicated, requires a frehs ROM, won't work here) which boosts the game so lags appear more rarely with it. Well, you can compile SNES9x with a faster clock cycle but that's very hacky and not recommend.
Okay, my layout looks ugly.
