Summary	06912: megadriv [rocket]: Graphical glitch in the ugliest screen of the game (and maybe of all the videogames) in Rocket Knight Adventures.
Description	In Rocket Knight, at stage 2 before getting the trolley, we have to pass trought a cave with chained spikes at the top and the bottom. In the video the action is fast, but you can see a spike at the left-bottom corner of the screen tha shouldn't be there. It remains there as some kind of sprite garbage until the screen disappears. I'm afraid this bug has some relationship with these ones; 06184, 06229, 06044, 06610
Steps To Reproduce	You have to play until that point at the stage 2. I'll try to provide a save state as soon as possible.
Additional Information	-A video with the bug: -Another video without this bug (Min 14:15): -Also I have the original cardtrige, but I can't capture the screen :(
