Rumble of SameBoy core is too weak on iPhone.
Sorry, that's not really enough information to start investigating based on. Can you let me know what app version and what your settings are in settings > input > haptic feedback/vibration? Also what game are you playing?

Hi, the app version is 1.22.2 on iPhone14 , all the 2 options in Haptic Feedback&Vibrarion are ON and Vibration strength is set to 100%.
I uploaded the game in https://files.xanyi.eu.org/roms/rumbletest/ , please have a try on RetroArch and SameBoy app.
@troilus Will be nice if you can provide some log as it helps for the diagnostic otherwise it will be guessing.
If you are using SDL joypad driver, it might be related to this issue.
Thank you.

Thank you.
Hi, I didn't connect a joypad, I used the in APP Retropad. I changed Controller setting to sdl2 it shows "iOS Accelerometer (0/0) not configured, using fallback" and Retropad disappear, only mfi works.

I tried this out and found that the rumble strength is inconsistent. I looked very briefly at the code and only see it starting a strong rumble. What this implies is that it's turning off the rumble too soon, it needs to let it run a frame or two longer. I'm hesitant to add that type of minimum to the frontend, it feels like it's overriding the core's intent a bit.

Thanks,That is to say, is the strength inconsistency caused by a problem with the core itself? If so, why is there a difference compared to the strength in the SameBoy app?
Yes that's my working hypothesis. I haven't read the sameboy code enough to know how its frontend handles rumble but it's very easy to imagine it handles it differently than the libretro core integration.
