@cthulhus You can edit the es_inputs.cfg and disable the start and select buttons so you can't access to that menu until you replace the original es_inputs again.

I see! I'll play around with it, then.

I have finally resolved it myself: the Bash Script itself was named "Master Edition" by accident, which led to this particular gamelist entry being ignored, with the bash script name being shown as the title instead, and since it has been ignored - no video.
Can be closed, but I will not delete this for now, in case anyone else encounters this or some of the friendly users who answered want to know where this went.

@chicuelo lost me there, I found the other post useful.

@mitu jajaja!! Yeah, between a messed up menu and non centered menu I prefer the not centered one that is redeable. Thanks.

I will edit the autostart file and see what happens when I connect it back to an HD screen (so I can prevent any surprises if I ever take the Pi to a friends house)
