As for the reset behavior, it seems to have mostly corrected itself with games on sys nand. I'm going to assume updating everything is the reason for it. Some games still have the reset issue if launched through USB Loader GX, but if I launch from system menu or priiloader it doesn't have that issue.
I would like to be able to cycle between sys Nand and emulated nands, and would need neek2o for that to be possible with Majora's Mask, so I would need to do that through USB Loader GX or something similar.
The Bootmii issue seems to be back: powering on my system sometimes hangs up and does nothing/boots nothing. I can circumvent this by holding the reset button to boot into priiloader, or remove my sd card so priiloader boots stating bootmii failed. I'm not sure what's causing this, but it seems to be bootmii. Are failed boots common behavior?
My USB Loader GX is up to date, and to reiterate the reset issue has been fixed for everything but Majora's mask. Ocarina Time functions fine with wads installed to sysnand. But loading a wad for Majora's mask installed to sys nand still does the same thing. The game loads/plays fine, but hitting the physical reset button on the Wii will stop the game but lock the system in a black screen rather than rebooting the game. Pressing the power button doesn't power off the system after this, and the power button must be held down in order to power off the system. Intended result for VC games is to reboot the "emulator" for the game rather than the entire system. Again, this behavior is not present when the title is launched through Priiloader or system menu, and only happens when launched through USB Loader GX
My initial thought was this was behavior caused by USB Loader GX and how it boots the game, but with the return issue of bootmii failing to load occasionally, I'm wondering if it's possible my Wii's boot settings could be the cause.

Return to: Priiloader
Shutdown to: Power off
Stop disc on startup: On
Light slot on error: On
