I'm not having any issues with the Gamate core, games load up fine while playing. I had a one awhile ago, it's really cool to see it on an actual screen, the games went from virtually unplayable to only mildly unplayable. Amazing work as always Kevtris! The Game King is especially interesting, the graphics are laughable, but the music and sound effects are surprisingly good, and just so weird sounding. I love it.
Oh, and thank you for addressing the issue with the menus in the 2600 core via analog video, it works perfectly now!
