i think for the most part, once we’ve agreed all the best systems, that would just represent the default set up in retropie. right now i think it’s up for debate the best setup and config for each system, so i’m not sure there’s much agreement, yet :) eg, that video_threaded option isn’t the default in 3.0 final because it apparently can cause sync issues (i don’t know what this means, but that’s what i’ve been told)
this should become better as we go – there a few spreadsheets linked in these forums detailing what games work on what emulators/setups/etc. eventually we should get a good picture of what is the best general setup.
my setup is definitely quite a bit different from what came with my retropie build (3.0 beta 3). i’m happy with it but i’ve not explored all the options.
