This differs from the current MiSTer core, as of the date of this issue.

This ROM makes for a good test: Super Mario Bros. (World).nes.smc.zip (copyrighted content removed)

Interesting. I think this is the first confirmed discrepancy against MiSTer. By the way, please don't upload or link to copyrighted content. I removed your original link.

Since it's audio, I wonder if the internal SNES core is producing audio as we would expect, but it's not making it out over the Pocket's i2s bus for some reason

One further thing of note, on ONE short playtest of the posted ROM, the Pocket did spit out some gnarly static during gameplay / until switching ROMs, but I can't seem to replicate it. Definitely incorrect either way ;)

By static, do you mean there was some garbage static audio? Not the screen was full of static?

Correct; audio static. Sorry, should have been more clear.

Edit: and yes, definitely -garbage- static, nothing recognizable.

I need to look into this more, but I wanted to note that I have also confirmed the audio issue. Working on MiSTer, nothing on Pocket.
