Lag on S22 Ultra
Can you document what games you been trying to play, or if you have the DS BIOS, or the dsi mode
With this information, there's nothing I can do. And the S22 is more than capable of running the emulator without issue. Make sure JIT is enabled in the "System" section in the settings. You can also try disabling sustained performance mode in the "General" section in the settings.
When I play I get bad stuttering throughout, it won't stay at a constant 60fps affects new super mario Bros. Namco Museum DS, and Super mario 64 ds
Hopefully in the future melonds software rendering will improve the performance.
Here's some adb log
Entered adb shell

I'm on s20+ exynos and i am also seeing the slow down after a few minutes of play, i have installed a DS and DSi bios, DSi mode is turned off, JIT is turned on. I see it happen on Castlevania dawn of sorrow and on the DSi firmware. If I pause and unpause the emulation it returns to normal levels of performance for some time. Tested turning off treaded rendering to no effect.
Any update on this?
Performance of this emulator will only improve if ever opengl renderer is implemented.
I don't have that specific device to be able to reproduce your problem. The closest thing I have is a Galaxy S10 and it doesn't suffer from the same problem. As such, you will have to be patient because addressing these things is not easy.
You can test apps on Samsung devices here for free: https://developer.samsung.com/remote-test-lab
@rafaelvcaetano JIT doesn't work on my vivo y11 snapdragon 439 performance. I tried it disable/enable the fps doesn't change but the threaded rendering really helps.
Does JIT only optimize in higher specs devices?
Performance is solid on 64 bit devices with thread rendering and JIT enabled, and should run at full speed on flagship devices. Performance on older devices, specially 32 bit devices, is very poor due to the lack of JIT support.
Maybe melonDS detected my phone as 32bit? What do you think about this?
But in DevCheck app my phone is 64bit supported.
