I'm on deployment, so no downloading and playing with stuff for myself. Did a search for retroarch and the first page of results didn't exactly cover my question...
How does retroarch do in comparison to MAME with regards to all the stuff that was merged from MESS? Not in terms of accuracy, but playability?
Can I use the very same files from the most recent MAME and play them with retroarch?
What does Retroarch do that MAME does not, and vice versa?
I will be the last person to die in my lifetime.
