is there a n64 emulator that works on psp. My friend told me about one but he forgot where he got it and then he got rid of it.

It is called Daedalus. Google that. It works, but its playability is debatable.

so it is laggy.

Systems that run software or games they weren't originally meant to be played on means it needs live conversion, so you are playing it, while it is synthesizing the music(if it does), playing sounds, developing graphics, taking your inputs, running the code according to the events within the game and your input, while converting a Live feed of binary data

That is my thought but I may be off somewhere

That is a remarkably un-scientific way of putting it. Think of it this way.

Running a N64 game is like getting Twista to rap.

Running a N64 game on an emu is like getting some other guy to rap Twista's songs while translating them into latin at the same time.

Naturally the second guy isn't going to be as fast.

But yeh, suffice to say it lags. A lot.

I doubt they know who Twista is

Just picked him coz he raps fast. Ok then, replace Twista with someone well known like... umm... Will Smith .

Except that rapping Will Smith is more like emulating a Master System...

Well that went off topic pretty fast.
