Finally we were able to figure out the problem with video settings and why it was glitching, also we fixed the memory card saving.
We re-arranged a bit how the game works, so after launching the game application you can change your settings and game control input, then you will be able to launch the game by going into file and click play.
You now can use the in-game memory card saving (save states now not supported). If you want to go back and change settings you must click ESC to exit game application and re-launch the game application to access it.
Thanks for your support!
