I can't find exact info but probably it's 2 ARM 11 266 MHz (or one 266 and one 133, not sure)
Theoretically it's enough power to emulate PS1 but it's only theory...
If it would be possible to make use of two cores it would go easier of course, tough I'm not sure if that's possible

Never joke like that again...please

So that also means that N64 could be emulated?

No offense but next time check specifications of console/hardware You want to emulate before You ask...
N64 is way more powerful than PS1

How do You expect to run this?
I know that DS was capable of running natively games that was written for N64 (with little remake for shaders and such effects) but running emulator of N64 on 3DS... I wouldn't be so sure about it... emulator would have to be written *VERY* effectively and recompiler part would have to be in Assembler for speeding things...

it might run ps1 but not at full speed for some games and don't forget you try to emulate on ARM so you need almost 15-20 stronger machine than the that you trying to emulate 33x20=660 so it might be enough for small games like rayman 1

Mhz are not equal to processing power. The ARM cores of today are far more powerful than the ones released 15 years ago. What you ought to check are MIPS values, not clock speed.

The 3DS is fully capable of PS1 emulation, the graphics side of things will be greatly supported by the GPU.

Power-wise the 3DS stands between the Wii and the Gamecube, being closer to the Wii. It will most likely be able to emulate the exact same machines those two emulate, the rest is a matter of implementation and optimizing.

an PS1 Emu on 3DS would be awesome *_*
all these games that made my childhood
Grandia, Digimon world, Raystorm, Rayman, Tales of phantasia (english patched)

foxi4 i dont agree with that sure ARM is powerfull but not that powerfull but ARM still need alot more horse power then x86 cpu for example reason is the ARM architecture is different then x86 in some point they are the same still ARM is low powered even some phones still can't emulate ps1 perfect and they got a way much better ARM chip then the 3DS

Emulating on hardware which shares the same architecture as the emulated machine allows excluding the transcription of instruction sets, PS1 emulation on mobiles has been perfected years ago, most handsets run the games at higher framerates than those rendered by the original hardware. The problem with emulating on a phone is that there are hundreds of handsets an emulator has to be compatible with, thus it requires a compatibility layer which in turn greatly reduces the possibility to unleash the full power of GPU's (some handsets even lack those so graphics have to be software rendered sometimes). This limitation is gone when specs are fixed. You can disagree, but be aware of the fact that you are wrong.
