to say that melonDS is 'very poorly optimized' is a vast understatement of the work that goes into optimizing it, as well as the power that emulation requires, especially in the case of the DS. sure, it's a puny 66MHz, but the fact that there are two CPUs and several other hardware components that you need to emulate with a reasonable amount of precision, makes it require a lot more power than you'd think.

also, we're developing a JIT recompiler, an OpenGL renderer, etc...

besides, you don't really seem to know well what you're talking about, because the 'video resolution option' is already implemented since 0.8.

there's already that option (Screen filtering). it's purely cosmetic though -- scaling and filtering are done on the GPU, so there isn't much of a performance hit.

have you also looked into video settings? you can try seeing if the OpenGL renderer is faster, or the software renderer in threaded mode...

yeah, the emulator core is the bottleneck there. not much you can do besides waiting for the JIT recompiler.
