Not claiming to be an expert, but I watched this video a while back. www.youtube.com/watch?v=OmKjVpVdHDQ
The impression I got is that PS1 emulation is actually pretty good, and N64 emulation is more like that Homer Simpson meme with all the clothespins on his back.

Ps1 is great because it’s a mips core, a funky 3d engine and the main weirdness is the spu.

The n64 is all weird (albeit with a similar but 64bit mips core).

  The PlayStation hardware is barely capable of 3D at all.
  
  Sure, it can accelerate some polygon math, but that’s about it. No texture mapping, no Z depth, no floating point precision, no anti-aliasing, no shading.

    It does texture mapping, it’s just not perspective correct. And floating point isn’t a precision

    and floating point isn’t a precision
    
    Floating point precision does not mean I’m saying “floating point is a precision”, whatever that sentence means.
    
    The PlayStation can’t use anything but integers to place points in 3D space.

    It does texture mapping but that’s all. I think it does very limited, basically gouraud shading.
    
    You have to clip your triangles, basically clip everything.

  Didn’t forget the rdram in the N64 that Sony didn’t use until PS2/3
