I recently got this SNES for free from somebody because of random issues with varying games. The game I tested it with is Super Metroid. I can't run up slopes and sort of 'float', and the energy doesn't display properly. Here's a video of what I'm talking about https://www.youtube.com/watch?v=7LGd2yVjWd0. I didn't get to record this part, but the sprite for the grapple beam is missing, and missile doors display as blue rather than red. The person I got it from said that AI doesn't work properly in Super Mario Kart either.
Does anyone have any ideas what it might be? I mostly dealt with fixing issues with it not powering on today, so I didn't get to diagnose the solution a whole lot. I cleaned the cart connector, replaced fuse/7805 and the temperature of all the chips seemed normal when I touched them.
