Tiny Toon Adventures - Babs Big Break has graphical issues in GBC mode. #41

While TASing this game in BizHawk, I noticed any time the screen transitions, there is junk on the screen like this:

Tiny Toon Adventures - Babs' Big Break (USA, Europe) 2020-05-29 16 51 18

I tested this in the latest upstream for GSR and the issue is there as well. I also tested this with BizHawk's GBHawk and this doesnt happen in its GBC mode.

and keep in mind, this only affects GBC mode, it is not present in GB mode.

Thanks for the detailed information. This visual glitching doesn't appear in r664, so I'm going to guess we missed something in #27 that is causing this.

This cart also has a title that runs into the CGB flag at $0143, something we may not detect properly. Will have to revisit our fix for this, but these should be good leads.
