New build runs fine on both n3ds and o3ds regardless of which firmware I load on both sysnand and emunand. YN loads consistently in 5m43s, and plays most sounds fine (you can see in the video a few BGM are in unsupported formats). Let me know if you'd like any additional footage or a different...
Loaded it up on my o3ds as well. Same results as n3ds as far as starting, hangs on "Debug console started" on 10.7 Emunand/9.2 Sysnand (using ARN ntr firm) while launching just fine on 9.2 Sysnand (9.0 firm) with AuReiNand. Sounds work well on o3ds and it runs at 25-26fps.
Test suite (~6mb)...
Still hangs at Debug console started on 10.7 Emunand (5/5 tries), 9.2 Sysnand (5/5 tries when booted with firmware.bin), and works each time I try when booting with firmware90.bin on 9.2 Sysnand using Aureinand on n3ds. Sound is working fine with the new 3dsx as well.
Launches effortlessly every time on n3ds 9.2 sysnand with ARN and a9lh, loads to the main menu and sounds seem to be clear with the debug menu reading 60fps. Gets stuck at "Debug console started..." when started in sysnand/emunand when not launched with 9.2 firmware (or 9.0. whichever firm boots...
