Finally got my SD-Card today and started playing around. Got most things running. I had so many problems using my xbox wireless controler, getting audio to work over hdmi, getting gba games to start. And i got so many things i want to know. It's so much fun just playing around and fixing things. I hope some of you can help me out with some questions

Leaving emulationstation with F4 and starting x doesn't work as i expected...
There was no LXDE desktop, just a smaller terminal screen with some info like temps, ip etc. I don't want to do something wrong and replace emulationstation at boot by installing anything related to a desktopmanager. Is there a safe way to just start the desktop?
Also someone mentioned that nintendo ds emulation is possible on android, but raspbian is arm too so why would i need a other OS for a emulator?
Right now i save each game via select and save state 0 is there any other way to save?(as i read somewhere that saving ingame is not possible). It would be nice to auto save and load state 0 for each game while closing and opening the game. Is that possible?
Is it possible to load a psone save file from the android emulator that i used on my phone to play ff? I don't know if emulators use some save file standard.
This is so exciting and fun. I installed Kodi and need to test it soon. Is there a way to use netflix? My Pi is becoming a all in one machine!
