did you know, visual glitches from errors in the code of most sprite based 8 and 16 bit games, don't look like what visual glitches from errors in the renderer? in fact, the most often interpretation of a visual glitch, isn't all too accurate! if it's a visual glitch within the code, if the game is sprite based (which means it's likely tile based in the case of older games) then it often has displays the wrong sprite for certain tiles or objects, which were usually split into multiple sprites if they were large.
