Yeah Ive been talking to one of the daedalusx64 devs but since it was never actually ported to linux that itself is going to be an issue. He mentioned that the project itself is mostly dead and no one is working on it at all(and all the devs are quite happy to just let it die as they've moved on to other things) though the code is on github(https://github.com/hulkholden/daedalus
) According to folks at #linuxmips & the internets the PSP & Ingenics chips share the same breed; MIPS32R2 so I was wondering if the dynarec from daedalus could be transplanted into Mupen?
Transplanting a dynarec from one emulator to another emulator is a lot of work, and you can end up with a lot of performance compromises making it work. If Mupen had no dynarec at all I'd recommend this, but I suspect it'll be easier to convert its ARM dynarec to MIPS. It'll take some bravery though, Ari64's dynarec code isn't really that pretty. I guess maybe whoever feels they can take up this task can spend a while evaluating both options first?

While it is true that the GCW's on screen display is limited to 320x240 most N64 games rarely went 640x480 :
It's more powerful than PSP, yes, especially in the CPU department. Especially since PSP had no L2 cache. I have to disagree with Pandora - while it's good for those things too, it also has some of the best dedicated gaming controls I've ever used in a handheld. And the OS is well suited for emulators, since you can draw directly to a scaled display with very low overhead, and you can get relatively low latency audio and touch, as well as good audio/video synchronization. That's a lot better than you can get coding generically for Android or PCs. It's a lot like GP2X was in this regard (I did some emulator coding for that too).
You're right that 320x240 is fine for most N64 games. This was more of a general complaint about the system. That, along with the lack of a touchscreen, makes DS emulation out of the question anyway, which made me a lot less interested in it.

You may be right about the original devs, but good luck getting them to work on it. notaz for instance has about a billion other things to do, and I haven't seen Ari64 anywhere in years. In that regard, I (or Lordus) wouldn't be any better anyway. Those two weren't original devs of either emulator anyway, you just need people who are experienced with emulator coding. I know there was a PS1 emulator for Dingoo that got a MIPS dynarec, so these things can at least happen.
What do you guys think about the CI20 single board computer? That thing is a $65 beast of a board from Imagination Technologies that runs debian right out of the box:
Honestly, I can think of several small computer boards that are as good or better than CI20 for about the same price, that also came out long before it. I'm not aware of anything new or interesting it brings to the table. It'd be one thing if we were talking handhelds where they're all different, but with SBCs there are many that run Linux and are all nearly interchangeable once you have the same software running. And you should already be able to get an N64 emulator running on an ARM based one (just not Raspberry Pi)

It's not that there's anything wrong with MIPS (my first emulator was for PSP), it's just that as of the past several years ARM has been in so many more devices that it's hard to be motivated to do work that's specifically targeting it. For most apps the CPU architecture doesn't really matter, but as I'm sure you know there's a lot of platform specific stuff in a dynarec.
I think it became this way because MIPS took too long developing competitive cores, letting ARM dominate. Ingenic had good market share a few years ago, but their CPU performance has fallen way behind since Chinese SoC vendors moved beyond ARM9.
