Playing https://www.digitalmzx.com/play/182/ in Chrome works; in Firefox it gives a JS exception:

Uncaught (in promise) DOMException: BaseAudioContext.createScriptProcessor: At least one of numberOfInputChannels and numberOfOutputChannels must be nonzero

This looks like it may be a regression from https://github.com/A...47c06e2827a50b.

I can't reproduce this in Firefox 79.0. Are you sure this isn't a Firefox bug?

edit: adding a check to make sure the data fetched from the SDL audio context is valid before continuing should prevent the crash but I'll have to check with Spectere to make sure it still fixes the Safari issue.

Updating status to: Fixed
Updating severity to: 5 - Critical
Updating version to: 2.92e
Issue fixed in: 2.92f
Updating Introduced In Version to: 2.92d

Fixed in GIT aab52a6e. If the channel count on the SDL AudioContext's script processor is <1, the code for replacing the AudioContext aborts.
