@dankcushions Thank you so much for the support. I thought it must be a video problem but if it is emulating like this (the way it is supposed to be) then it is no problem. I am pretty sure Mario Kart 64 was intended for CRTs as well so that is why there are those lines. I also run PSX and N64 at a low res so that they perform well. I will probably dump some PSX Bios and configure some settings so that I get access to all the benefits of the system.

Once again thank you to everyone's support.

If you are using Wayland as your display server (now default on Ubuntu 22.04 on) try switching to Xorg instead.

thanks !, yes I mean emulationstation
