I did think someone was making them compatible with Old 3ds models but that never became a thing and yes old 3DS does crash so you're not the only one!
I was quite happy to try out these 2 ports but a damn ARM11 error killed my happiness.
Oh, and, for future releases, do you plan of optimising it for O3DS consoles?
The latest ".3dsx" that Saturn provided works great on my O2DS! I'm very hopeful for this port's future!
EDIT: How can I compile a cia for myself as it seems there have been more commits done after the latest 3dsx post here.
