Hello, I am calling nds schedule event and I can not figure out how to calculate delay which lasts for 1 or 2 frames. So how to calculate it reliably? To do so for 2 frames is it reliable or calculate it for 1 frame and then do one skip in function event callback, so in total 2 frames?...

one frame should normally be 6*355*263 cycles, though in theory it can vary.

What exactly are you trying to archieve?

Thanks. It is about emulating touches. If you call functions without delay game sees only the last call I think, because it does not register other function calls.

the emulator scheduler isn't the best place to implement something like this, you're probably better off just hooking that in somewhere here: https://github.com/Arisotura/melonDS/blob/master/src/frontend/qt_sdl/main.cpp#L542 so that it will go before or after every call to RunFrame.

If you want to discuss this further I'll recommend hopping onto our IRC channel/Discord server: https://melonds.kuribo64.net/board/thread.php?id=3
