No video output when frameskip is enabled #2

Closed schmurtzm closed 1 year ago

schmurtzm commented 1 year ago

Hi, I'm testing Chimerasnes on Miyoo Mini (little linux handheld , SDL1.2) , Chimerasnes works really well on it except if I enable frameskip (auto or manual) : when it's enabled it 's like if the core doesn't send video output anymore.

Any idea ?

This is going to be difficult to debug as I don't have this device or any similar to it. I'll see if I can use https://github.com/TriForceX/MiyooCFW with qemu and debug that way.

Out of curiosity, does lowering the frameskip threshold help? Also, can you check with snes9x2005 and/or snes9x2010 to see if frameskipping works on those - I'm using the same method, so I'd expect it to fail with those too.

Hi, OK forget it, I have tested with Snes9x 2005 and 2010 with almost the same result (not a total freeze but very bad result like a slideshow). And finally I just realized that it comes from our OSS sound driver which doesn't like frameskip. Once replaced by SDL frameskip is OK. So we can close it. Thank you !
