I was playing Super Mario Bros. 3 recently and spent some time observing the right edge of the screen. I understand what attribute glitches are and why they occur, but I noticed three distinct types of glitches on the right side:
1. Color inconsistencies
2. A 'displaced' column of graphics from the left edge
3. A column of graphics that didn't match the left edge
I also saw a few combinations of 1 and 3.
Are all of these cases rightfully labeled as attribute glitches or are examples 2 and 3 consequences of mirroring? Case 2 makes sense if the nametable is wrapping around, but why would case 3 occur?
I'm just curious whether I'm seeing a single technical phenomena or several in combination.
