When playing 2D games such as Shovel Knight, The binding of isaac, and emulators for snes and nes it is the most noticeable, it is a ghosting/smearing effect across the whole screen but you can see it easily in the backgrounds. I know this is a console specific issue as my O3DS doesn't have this issue of ghosting. I'm pretty sure this system hadn't been badly damaged and that it is in almost 100% condition as I got it from a friend who barely used it.
I have asked this question before in this server yet I didn't get a response. but after a bit more research of my own I think that maybe this issue might be from a loose ribbon cable for the screen or something along those lines and I might be okay with opening it up if it can be confirmed that that is the issue. If it is recommended I could also check if there are any console repair shops in my area so I that a professional may take a look at it.
Thanks so much for reading and for trying to help me :)
NOTE: When using Snes9x it very much helps when I add a stretch the game to a different resolution, blurring the game
