v3.9

• Further clean-up of the code
• Fixed rare black screens with mounting SD cards
• Updated the built-in payload chainloader to handle multiple payloads. This was inspired by Fix94's arm9select. Create a "payloads" directory inside the rei folder, put a "default.bin" inside (rename your existing arm9payload.bin if you have one), and (optionally) these other payloads: b.bin, x.bin, y.bin, select.bin, start.bin, right.bin, left.bin, up.bin, down.bin (press the matching button together with L and R to load the payload). Furthermore, the new loader will automatically perform the screen init before launching the payloads if this wasn't already done by A9LH itself.
• Added dual emuNAND support. Please note that you can't have two 9.0 emuNANDs, and that if you want a 9.0 emuNAND it must be the first one. To launch the second one, press R + B in updated sysNAND mode, or just B in regular mode. The code will just fallback to the first emuNAND if the second one is not found.
