It looks like you trimmed a tad close to the NAND on this side. It looks like the 3v3 and GND vias on that side are still partially there, but the decoupling cap isn't. It might work, it might not.
You should put on whatever games you ripped from your physical discs. As for bluetooth, that's completely up to your soldering capabilities. It is definitely a bit harder than most of the other soldering in the portable with the scratched traces and all, but if you have a good craft knife / good flux / a steady hand, it's not insane.what games should I put on this thing? I'm also considering adding the bluetooth module because of the theme and all, how hard is it really?
