A (hopefully) final update to my first switch hacking saga. XD
I got my wireless function working again, and I managed to get rid of my slow emmc mode!
At some point during my hacking endeavors, I ripped the Dat0 trace and rendered my console unbootable...

While repairing that, I also ripped the CLK trace... So I scraped some of the solder mask away on the trace, then used uv-cure resin to mask off all the surrounding solder pads. I soldered to the tiniest pad that you can see above to the trace I exposed with 40awg magnet wire, then covered the whole thing in uv resin. I had to also repeat this process on the CLK trace.

Once I had finally gotten finished cleaning up my attempted failure of soldering to the emmc port pins (I shorted a bunch to ground since basically every other pin on the port is a GND pin -_-) I realized I had accidentally blown/brushed the tiny capacitors to the left of the APU shielding off, and these are ABSOLUTELY VITAL to the functioning of both wifi and bluetooth of the console. I repeat, if you rip these caps off, the joycons won't work unless docked in the switch, and you won't have wifi.
Here are the caps in question after I repaired them (I ALMOST ripped the trace of the one closest to the APU enough that I couldn't recover, but luckily I was able to offset the cap to hit the trace and the remaining pad on the circuit.)

And finally, if the above image doesn't QUITE give you the understanding of scale as to just how TINY these things are (literally smaller than a grain of rice) here is a photo of a single capacitor, resting on the pad of my thumb, a mere 2 finger-print traces long, perhaps 1 finger-print trace wide.

This was a real burning crucible experiment for me. Failing to fix this would mean I had a functioning switch, but no wifi and no wireless controllers could be used. I have an 8bitdo arcade stick that's compatible that would have been USELESS without this being fixed. I spent approximately FIVE HOURS positioning, cleaning, fluxing, tweezing, tweeking, nudging, holding my breath, swearing quietly, stabbing myself accidentally with pointy tweezers, and then finally getting a good connection on both capacitors to end with a RESOUNDING SUCCESS OF WORKING WIRELESS!
As far as my slow emmc problems go, I have a patched V1 and had 47O (47 ohm +/- 5%) on DAT0, CMD, and CLK, and hekate was reporting half-speed on my emmc. I replaced the 47O with 47RO (47 ohm +/- 1%) on CLK, and then put two 47RO in series on DAT0 and CMD to give them a total of 94 ohms resistance each. Doing this seems to have solved my slow emmc problems.
I'll be around, because I still have my GF's switch lite to hack, and potentially a few friend's switches. Keep hacking guys and gals, and if you think you've toasted your console, just consider how much I had to Frankenstein mine to keep it alive, and DON'T give up.
