Crash with error code 2162-0002 on launch.
Also - I will not test the next version of this, just to set a point. Here is why.
Using the ftp app to upload content to the Switch is something, thats vastly preferable to other methods of transfering data to the switch (especially to "try" somthing), because we want to minimize the amount of times we "snap" the switches stand open and closed, because thats a part of the console that can wear out (and has for some people according to reports).
In this case uploading the 16MB folder took close to 20 minutes, because it consisted of unpackaged files down to every last image texture, because there was no form of packaging/compression used.
You then wait 20 minutes, start the dang thing, get a crash - go throught the 4 minute process to launch HBL again, to see if it can be replicated (it can), then do the 4 minute process again, to get ftp access again, to get the files off of your SD card - which again, takes longer than it should - because no packaging, and no compression.
Testing actually consists of getting people out there to do work on your behalf. If you can't even be sure, that the code you uploaded runs - you are in fact outsourcing part of your production ("wouldnt it be nice, if we could add another supported platform"), not asking for testing.
If your "testers" have a bad experience while trying to get your executable to even run, chances are - they wont be back.
I wouldnt have said anything, if that was a first - but its the third time, this happened in my case. People trying to "hail marry" their development without any form of on system testing - has to stop.
(Queue the here is a newly compiled version "does it work now?" postings..)
