It is ALWAYS the new things that give people issues, currently the main issues are:
NOR
RAM (for browsers)
Rumble
The only thing that didn't change is PSRAM.
People that work on this or already know about the 3in1+ issues, knew this long before you even got PMs of issues.
As for being hysterical over the issues and posting in almost every 3in1 post the same message of the issues, doesn't get it resolved any faster. Unless you can write Japanese AND write code, people like Roudolph are not going to push something more compatible sooner.
YOU AS A USER, have no control over when the programmers release a fully compatible version, that includes the teams on flashcart firmwares that do integrated 3rd party hardware. YOU WILL GET FULL SUPPORT WHEN THEY HAMMER OUT ALL THE ACCESS ISSUES.
All you can do right now is wait for a better compatiblity release. Operative WORD here is WAIT.
