Awesome that you updated jBoy for the current SFOS version and provided the aarch64 build.
Have you considered releasing the source code? Allowing others to be able to contribute would make it a bit more future-proof and personally I'd like to maybe try redesigning the look of the d-pad a bit. The non-centered landscape game screen also looks a bit odd on a long Xperia display. I suppose that design choice was more beneficial with shorter displays :)

As this will probably no long work since Sailfish OS 3.3.0 a possible workaround:
Replacing busybox coreutils with the gnu version will probably help, but you could also "patch" the binary.
The emulator checks if the size of the rom is at least 32768 bytes, which fails since Sailfish OS 3.3.0. For that we will make it pass by always returning 999999999.
For that, execute from the terminal (as user root!):

TOHKBD still not working in game. I think a slider would be more convenient way to change the size of the keyboard buttons. The size animation is quite fast anyway so it's not too easy to hit it to desired size.

Nice work, and very configurable. You are also offering a tablet build, but it has some aligning issues. In landscape, the B button overlaps the screen. Portrait looks good, but after rotation and returning to portrait the upper part of the sceen is no longer visible.
I don't know if you have a tablet to test with? I could have a look at it, but a git repository would help in that case. That is, if you want to share the code ofcourse. Already noticed it has a lot of german variable names in the QML code :)

Thanks, please try the latest version.
Unfortunately I own no tablet, but the SDK is able to emulate it, so I had a look at it and think I have fixed the issues.
Yes, using german in variable names and also comments is a rather bad habit I have.. ;)

Very nice. Added my Pokemon Red rom a c in the end and it worked nicely. I tried actually playing for a while now and I think you could make a resizable controls. I found that the directional keys would probably be more comfortable to use if the pad would be smaller so I could move my thumb in a smaller area. In the actual gameboy you could pretty much keep you thumb in one place and just tilt it to where ever you wanted to go. A and B might also be easier to use if they were more close to each other.
Also, did you get my email and were you able to do anything about the tohkbd support?

Thanks, yes I know what you mean. I think resizeable controls are a good idea - I will include them in one of the next updates.
Yes I received it and took a look at it. I think the problem is that I ignored the event.isAutoRepeat.
I will include this in the next update (for jBoy Color and jBoy), I hope tohkbd will work then.
