@Takokeshi you were right. My *nands were somehow re-linked. Thanks for the call out!
Theory below but here’s proof of the last time I formatted my emunand:
I fixed it by:
Installed VC Mario vs Donkey Kong in Emunand

This time starting the VC game crashes my 3DS:

I think this is the VC GBA result @CoolMe was warning us about.
I confirmed Mario and Donkey Kong NOT show up in Sysnand Data Management.
As a test I installed Mario and Donkey Kong on Sysnand and it works great.

Played through 1 world (score of 28000 with 6 Marios as a marker)

Switched back to Emunand and now Mario and Donkey Kong works (installed on both *Nands and pointless…as predicted.)
And also as @CoolMe predicted my save game from Sysnand is there

same stats as above. Never played this game before on Emunand (or ever)
Soo, all that to say this…just walked through the proof that VC GBA games installed on Emunand are broken and actually play through Sysnand.
edit: and for the kicker? When I exited the game it dropped me into Japanese Sysnand. Myth confirmed.

Not blaming 3DSBank for my error BTW!
Wouldn’t be fair as I don’t think it was designed with Sys/Emu nand flippers in mind but I honestly don’t know that for a fact it was root cause right now. I’ll have to do more tests at a later date to see what’s going on underneath.
Theory below but here’s proof of the last time I formatted my emunand:
I fixed it by:
- I removed 3DSBank, its configs and the copies of the Nintendo3DS folders (just moved them elsewhere in case I needed them for recovery or something….looks like not but safe vs sorry.)
- I reran TinyFormat and went through the initial setup again. My games and themes and everything were still intact so didn‘t hurt anything to do it again. :-)
- I did a quick install of Alien On The Run on my US Emunand and it correctly does NOT show up on my Japanese Sysnand. Whew!
