I haven't experienced any of these crashes. Granted I only have one game on your list "Majora's MasK" and tested it for a good 2 hours but it didn't crash.
Not one single game I have installed gives me these crash dumps and these include:
GBAVC (All Pokemon titles, LOZ Minish Cap) DS forwarders (R4i 3DS RTS Flashcard/ All DS Pokemon titles), GBVC titles (All Pokemon Games, some VC Pokemon Hacks "Pokemon Brown"), SNESVC titles (Aladdin, The Lion King, Super Mario All-Stars, Castlevania X, Super Mario World, Mortal Kombat 3, Zombies ate my neighbors) to name a few. Every one of my 3DS installs run perfectly fine as well.
I have seen reports of these crashes frequently. Espeically with HomeBrews in .3dsx format. I have only tested a few of these like 3DSident, PokeSlow, and the screenshot tool but they worked just fine. If anything even faster than they used to. It's just weird that some people are crashing like crazy and others like myself, haven't seen a single title crash on Luma 8.0.
