It's almost certainly not going to be coming any time soon. There's no known exploit.Any progress on kernel access for 2.1? I haven't seen anything, but maybe you guys know of something.

It's a well known fact that interpreters and non-JIT emulation is accurate but slower. Try running Dolphin on interpreter and software rendering. It'll be accurate as hell, but very very slow because it doesn't do any recompiling so that it can just 'run' code on the CPU. gpsp has an interpreter and dynrec core, and 2.1 can only use interpretation.
How can GPSP be that fast and even tells you that dynarec is enabled in the settings?

The PSP's gpSP uses JIT emulation and skips a lot of emulation (assuming you're using Kai's fork). It's very performance oriented but has poor compatibility. That's why back on my PSP I ran uo gpSP Kai (after Exophase left the project due to dramatic reasons) and, eventually, TempGBA4PSP. Kai for performance and TempGBA for compatibility. Pretty much Exophase did some impressive work and that's why people fork off of it a lot.
To be honest I was kind of guessing at what your question was. The question still doesn't make much sense to me with "PSP" replaced by "gpSP". Sorry.
The unofficial retroarch port of GPSP is almost perfect in terms of speed on new3ds and has a decent amount of fps in O3DS (but it doesn't have sound). In the settings, you can see that "Dynamic Recompiler" is enabled. What I'm asking is, how is that even possible?
So right now, a lot of people are seeing RetroArch's weaker dynarec vs CitrAGB interpreter, dynarec emulation is that much better for performance. Also, it's not hard to get speed out of an emulator, it's hard to get speed out of it while still having decent compatibility and accuracy.
Though, maybe this will lead to viable options. CitrAGB for those with the kernel exploit that allows them to take better advantage of their hardware and RetroArch for those stuck without a kernel exploit.
EDIT: Nevermind, I should have taken more of a look at the 3DS port of RetroArch instead of making assumptions.

That would take a lot of work. Remember, a lot of those emulators were designed with a lot more power in mind. gpSP was designed for performance on a weaker system and is open source as well. That's why it tends to be forked for other lower end systems. I haven't poked at the source code for VBA-M, but I imagine it would be far too much work to try to port.
That would make a lot more sense and I'm surprised more people weren't suggesting this.
Well, let's hope SOME working GBA emulator comes through soon.
Also, I'll be updating my files in a little while, so for those missing a working BIOS file and not having luck getting emulators to work, shoot me a message.

I asked mgba if they are making a port for 3ds. Maybe mgba will be better optimized than gpsp.
I looked into that and it's just a stub, it's still actually using an interpreter. I may move my dynrec work over to RetroArch just due to that having a cleaner setup (and a working menu, and maybe GPU acceleration? Might need to check on that one.) Would be better in the long run imo.

32GBs is the baseline for 4K video editing these days and lots of recommendations for 64GBs but for games 16,GBs is honestly plenty for a long time. -
