The Soundhax entrypoint for all versions ≤11.3 is very easy and fast. No doubt. But where is the problem once B9S is installed? To prevent possible problems with older versions an official update after installing B9S is part of The Guide. On the other side Seedminer is largely automated and not much harder (anymore). Not really a reason for searching consoles on low versions.
I can't say that I'm a fan of premodded systems. The buyer never knows what they get and they do not learn anything (and then they don't know anything about CFW).
Do you know if there is any other way to speed up the process for doing multiple DS’s?
If I was to install B9S on a big number of 2|3DS consoles I would do it with ntrboot. Assuming an "SD template" of all needed files is ready on the PC:
Copy to console SD
ntrboot → install B9S
GodMode9 script to copy boot.firm to CTRNAND
NAND backup, finalizing setup
Copy NAND image and SD content to PC into a folder named after the serial number of the console
It is two minutes of work and some more minutes waiting (create NAND image, potentially official update, installing small homebrew CIA files)
The immersion part is the only thing I like about vr that's why I returned Nreals too much open space made them off putting cool concept for sunglasses kind of expected it but wanted to try them at least
