nds emulator????

[ScarecrowDM]

There's still plenty of room to optimize in Desmume, I'll give you that, but you also have to remember it does graphics in software, in addition to the emulation, so of course it'll be slower than PPSSPP.

You can always choose OpenGL backend, you know.

Here DeSmuME is fast even without JIT, anyway.
Main problem with DeSmuME is his locked internal resolution and the devs don't giving a flying gently caress to implementing this (and that's ok, they can do what the hell they want to).

There's a guy somewhere working by himself to implementing this, but I don't remember where.
