There were attempts for a 3DS port by other devs, but as far as I'm aware, none got completed.
And no, I'm not planning to engage in any more ports, but anyone with expertise in porting can give it a try - Sonic 3 A.I.R. is open source after all.

If you don't mind, you could send me the project you're testing with (via DM), so I can have a closer look at what's happening.
Also, which version of OxygenApp are you using? I guess it's the one shipped with latest S3AIR stable version (v24.02.02.1)?

If you can upload the crashdump.dmp file somewhere, I can have a look into it.

Yes, this is known and actually a major reason why there was no Android test build ๐
But I'm working on it already, and hope to fix it soon.

No changes there - the S3AIR Android versions have always been built for both 32-bit and 64-bit devices. In fact, practically all Android devices are 64-bit nowadays, so it would bequite ridiculous to not support them.
Maybe that person meant something different instead?

Including a bunch of new development utilities for modders (accessible if you enable dev mode in config.json).
Enjoy!

Sonic 3 A.I.R. has a new stable update!
github.com/Eukaryot/son...
I actually planned to release it tomorrow, but it leaked much too early, lol.
I'll still make the larger announcement tomorrow (when it's Sonic 3's 30th anniversary).
Feel free to have an early look right now already. Have fun!
