Just looking on youtube, you can find binaural beats for pretty much anything: inflammation cure, pain relief, changing your eye colour, finding love and becoming rich. All the ones I've looked at feature comments from people claiming they've helped them.
They can't possibly do all of the above and I don't think there a studies proving anything but a placebo effect.
And, without truly believing in them, they never had any effect on me. I've tried them in my youth.
I don't think this ever happend to me. I started on the GBA and to this day every single RPG I played on there holds up - might be specific to the genre. I never played much else.
