Gameboy Emulator for your iPod?

"A single emulated instruction typically takes around 5 instructions, causing the emulated machine to be 5x slower than the processor running it." Your comparing apples and oranges. Some processors can do 1 instruction in a number of clocks and some can do a number of instructions per clock, some processors require several instructions to accomplish the same thing that another processor can do in 1 instruction! So what I am saying is, it depends! :)

"Not that insane, seeing as the iPod sports the equivalent of 2 of the Gameboy's processors." A single emulated instruction typically takes around 5 instructions, causing the emulated machine to be 5x slower than the processor running it. Getting near-full speeds on just twice the horsepower is impressive.

I admit that I'm one of the many that are dazzled at the sight of 10 year old games running on modern gadgetry, and getting excited that it runs "almost as good" as the outdated gadget it was originally meant for. It really doesn't make any sense, but there you have it.

"but it looks like they have Mario running close to full speed ... on an iPod ... which is insane." Not that insane, seeing as the iPod sports the equivalent of 2 of the Gameboy's processors. But it's still brilliant that they've got this working.
