Zelda Link to the Past buzzing after rewind #89

Closed badvision closed 3 years ago

badvision commented 3 years ago

Anywhere in the game, if I use rewind there is a constant low-frequency buzzing sound that never goes away. I can save the game, quit to the main menu and then it resets sound and that clears up. Also if I save state, reset the core, and restore state the buzzing is also present. I suspect it's something to do with the DAC samples that gets corrupted but I can't quite tell.

Not all sound registers are saved in the savestate, because I assumed the sound to fix itself fast. If that's not the case, more registers must be added. Please upload a savestate that leads to this sound, so I can reproduce it.

You got it! Honestly it is super reproducible if you use the zelda link to the past / four swords, launch link to the past and just hit rewind at any point. I can reproduce it pretty readily.https://file.io/BX0ZNj3KTbcm That link will work once, let me know if you need a more semi-permanent copy or if the link goes bad.

Also: Thank you for responding so quickly @RobertPeip!!

Could reproduce it myself now when it's totally quiet usually: I should be able to see why this happens

RobertPeip commented 3 years ago

fixed. You can either build yourself, use a testbuild available on MiSTer discord or wait for the next release

Happy to wait but ... damn that was fast. You rock! Thanks so much. :)
