Bad Apple Demo Audio Corruption #97

I know it is really a non-issue but i wanted to mention it. I tried the "Bad Apple" Demo video on your fpga core and video works fine but audio is corrupted. You can hear the first milliseconds of audio but then it loops constantly.

On my SD2SNES with original SNES or Super NT it works fine.

Most probably this is an issue that doesn't need to be fixed but i would find it interesting to know why this error occurrs. Maybe this demo uses some unusual hardware trickery? I don't know.

Thanks for your great core and your effort for the community!

I can confirm the issue. Most likely something isn't emulated correctly on the MiSTer core, and that gets carried over to my Pocket core. As for what in particular is causing it, we'll probably never know, as tracking these problems down is very difficult and requires a lot of motivation.
