first: Perfect script. RetroPie makes much fun, and is almost perfect working.
But here’s a little suggestion for the script.
Is it possible to make an update check for the sources? So first the script looks, if there is a newer version. If not, then it will not be compiled.
As i remember, the script compiles without checking?!
And saving in the script, which emulators are installed would also be very good.
I think he’s asking for it not to recompile the latest source if you already have the latest source compiled. So then you could check for updates without the risk of needless recompilation. But I’m just speculating b/c I haven’t tried that.
