However you can probably write the main parts that need performance as C based Python modules, and write "the rest" in Python. (Whether "the rest" is substantial enough to warrant it is hard to say.) This is the route taken by any Python modules/applications that have critical performance requirements. As for useful advice, I don't want to put you off but writing a complete console emulator is not a trivial project by any stretch of the imagination, and you'll also need to have very detailed specs about the SNES's hardware (CPU, video hardware, memory and IO maps, sound hardware etc), as well as have copies of its firmware (BIOS/ROMS etc) in order to even be able to begin to work on such a project. Additionally, there's already (or there was several years ago) several SNES emulators and doing another one just for the sake of it, well, is it really worth it? Maybe something a little more accessible might be to implement a MIPS CPU emulator, something like this: http://weblogs.mozillazine.org/roc/archives/2010/11/implementing_a.html or this: http://codu.org/projects/trac/jsmips/ And then see how fast you can make that without resorting to C, like the guy above did in the browser.
