[SNES] Real hardware issues

[Max833]

Every single game ever officially sold has been tested with bsnes (with firmware roms), and zero bugs are currently known. But there were some "hardware issues". These looked like bugs but were confirmed to occur on a real SNES.

We should keep track with real hardware issues.

I used the European cart, but that doesn't probably matter. Screenshot: https://user-images.githubusercontent.com/53529402/131505438-4e806090-6ef9-42bf-8f2d-f2d8e809c524.jpg	ZSNES forum

More infos about Blargg's issues:

Listed are music tracks that have been tested on hardware and verified to sound wrong or odd, either due to a bad rip or because they just sound that way. Refer to this if you're developing an emulator and find a music track that sounds wrong, before you look for a problem in your emulator. SPC tracks have been verified by loading them into the SPC-700 unit on a SNES using a custom development cartridge.

Good idea; I have moved the content to the GitHub wiki here; https://github.com/ares-emulator/ares/wiki/Game-Bugs

We can keep this page up-to-date and link it with the Website in future.
