Freeze upon attempt to exit/suspend #90

Closed wesmo closed 2 years ago

wesmo commented 2 years ago

Device: Powkiddy V90 running Miyoo CFW 1.3.3 Version: fake-08 0.0.2.13

Issue: When pressing either the start-select button combination or suspend screen button in-game (rom already loaded and playing) the emulator freezes. Only solution is to switch v90 off and on again.

Thanks for reporting this. I've experienced intermittent freezing when exiting the emulator, but it sounds like this is every time if you suspend? Also, what is the start+select button combination supposed to do? Is that also suspend?

Sorry i should've been more detailed:

1 - the start-select combo is bound by gmenu2x to take a screenshot 2 - the button that is used to suspend (located directly under the screen between the dpad and x button on the p90) is used to suspend the screen from gmenu2x in the miyoo cfw. In most emulators I have tested (pcsx-rearmed, gambatte dms, gp2x, smsplusgx) this button is the screen that brings up the emulator's option screen and allows you to select exit. 3 - The issue seems intermittent. Sometimes when I press the suspend button the fake-08 menu prompt comes up fine and allows me to select exit. Other times the emulator just freezes. I've experienced this behaviour in-game with the following cartridges: original celeste, picoracer-2048, waverace legend and picofox.

I've finally started looking in to this some more, and it looks like it has something to do with the callback that fills the audio buffer. I've tried a couple things that seem to help, but I still saw infrequent freezes. If you are still around and would like to check it out, I'm attaching that build here

Pretty sure I found the actual problem and have a fix. I can't get it to crash any more with this build

Newest release includes this fix. Closing.
