yes I know.
that's why I didn't mention the PSP's PS1 emulation, but the N64 emulation.
I never said that though, but it's pretty much a fact that the New 3DS is more powerful than the PSP in every way. not just because it "has more hz" but because of pretty much everything in it really ahah (even the regular 3DS is more powerful than a PSP btw)
I'm on the lesser informed side of this stuff, but I can tell you straight out that your understanding of emulation is massively incorrect. Power doesn't mean a darn thing. Arguable, the O3DS' raw power is greater than that of an original Xbox (Which can run Dreamcast games at a decent speed) and even rivals Wii, but the architecture is what hinders the system. You remember how there was a big stink over the Ice Climbers getting cut from
Smash? It is because the architecture put limitations on what the developers could do with the AI, so they scrapped the Ice Climbers because the system couldn't run it properly (Or it just didn't work at all).
Also, for another example, I remember hearing a while back how the most optimized SNES emulator for a smartphone required close to a 3Ghz CPU before you could even hope to play games at full speed, and, even then, how much had to be compromised. Meanwhile, as far back as Win. 98, people have been able to play SNES games at full speed, and then there was that whole big stink that happened when Apple announced that you could play the latest PS1 titles on a Mac (This was before the 2000s).
So, the first thing you need forgot about when it comes to emulation on alternate devices is that raw power means something. It does help, but is second place in comparison to the system's architecture (Which is the whole problem with the 3DS).
