From Reddit saved post — r/RetroPie, u/cyqu, Mar 07 2016 https://www.reddit.com/r/RetroPie/comments/49amv4/8bitdo_controllers_guide/ #THIS IS OLD. This is an old post with outdated information. See the RetroPie wiki [here](https://github.com/RetroPie/RetroPie-Setup/wiki/8Bitdo-Controller) for an updated guide. I've left the old post up for the sake of reference, but do not consult it for anything recent. Thanks for to those who originally contributed.   --- ---   #Welcome to the 8Bitdo Controller Guide. This post will be pertaining to any one using an 8Bitdo made controller with RetroPie 3.4 (Linux Jessie) and up, but will not be covering using it in any other situations.   ##General Information ###8Bitdo - The company [8bitdo](http://www.8bitdo.com/) is a company based in Hong Kong dedicated to making Bluetooth controllers and other small electronics. They have recently grown in popularity among the RetroPie community for their retro-themed controllers that are high quality, wireless, portable, and have familiar (Nintendo style) layout. **tl:dr:** 8Bitdo makes controllers. ###8Bitdo - The controllers The products we will be talking about will be the [NES30](http://www.nes30.com/)/[FC30](http://www.fc30.com/), the [SNES30](http://www.8bitdo.com/snes30/)/[SFC30,](http://www.8bitdo.com/sfc30/) and the [NES30 Pro](http://www.8bitdo.com/nes30pro/)/[FC30 Pro.](http://www.8bitdo.com/fc30pro/) *We're are leaving out the [ZERO](http://www.8bitdo.com/zero/) due to its impracticality for gaming, but if there is popular demand for its documentation, we will cover it.* All of the controllers listed are Bluetooth controllers (although they can be played wired) and have a d-pad, two shoulder buttons, a start and a select button, and four right thumb buttons (A,B,X,Y), the exception being the Pro controllers that have four shoulder buttons, and add two joysticks along side power and paring buttons. They also all feature multi-color LED lights to show what mode they are in, and a micro-usb port for charging and data transfer. The controllers are named according to their styling (NES/Famicom and their super variants). The shape of the controllers are *similar* to what you would expect, but not exact replicas of the original controllers. Build quality is quite high (IMO), and even the unboxing experience is very pleasant. However, the controllers are quite expensive compared to wired alternatives (iBuffalo, etc.) All of this means that the controllers are well suited for a RetroPie machine, with the "Pro" variants being needed for the more advanced emulators such as N64. **tl:dr:** 8Bitdo controllers are high quality controllers that work well for RetroPie. Check their website for more (arguably poorly translated, if translated at all) details.   ##NES30 Pro/FC30 Pro #Use Note: This section applies to both controllers with firmware version 1.68(+?), but I will refer to the two only by the NES name for simplicity. ###Manual [Here is the official manual that comes out of the box.](http://imgur.com/m2h3TnL) It contains some poor translations and has some missing information. We will be following and quoting this while adding on information. [Here is their online manual,](http://www.8bitdo.com/nes30pro/Manual.html) it adds some information but is still not complete. Both are available [here,](http://www.8bitdo.com/nes30pro/Support.html) and may be updated versions.   [**Contents of NES30 Pro Package:**](http://imgur.com/YysekkA) ○ NES30 Pro Controller (Charged) ○ Manual ○ Micro-USB Cable ○ Key Ring ○ Ring Stander - Many people think this is attach to a surface to hang the keyring off of, but it may be in fact to [attach to your phone in order to stand it up](http://imgur.com/fBZsLpL), presumably while gaming.   **Modes** Out of the box this controller is capable of 5 modes, shown [here.](http://imgur.com/tQNyDr9) You can tell what mode you are in by the led on/off pattern while disconnected from Bluetooth. Mode 1 (and mode 5 if you are going to be playing wired for some reason) are the modes pertaining to us. When you boot into mode 1, the LEDs should flash blue once then pause. You can see the difference when you boot in mode 2, for example. The LEDs will flash blue twice and then pause. The controller is also capable of other modes after an [extended firmware download,](http://www.8bitdo.com/nes30pro/Extend-firmware.html) but again none of these pertain to us. **tl:dr:** Turn on your controller by simply pressing the power button to use mode 1.   **LED Status Patterns and Colors** Instead of having two LEDs beside the micro-usb port, the NES30 Pro sports a wrap-around light on either side. These are the lights we are referring to. ○ No light - Controller is powered off or is in sleep mode. ○ Cyan flash - Controller booting. ○ Yellow flash - Controller shutting down. ○ Blue flashing - Bluetooth is disconnected, device is discover-able. Flash pattern indicates current mode; one flash before the pause = mode 1, two flashes before the pause = mode 2, etc. ○ Breathing blue - Bluetooth is connected. ○ Solid red - Controller's battery is low. ○ Flashing green - Controller is charging. ○ Flashing yellow - Controller is in firmware update mode. ○ Purple flash - Connection and pairing data has been reset.   **Buttons and Basic Function** For clarification, the power button is on [the left and the pairing button is on the right in this image of the bottom of the controller.](http://imgur.com/rh5Rres) ○ Power on (into mode 1)/power off - Hold power button for three seconds. Powering on = Cyan flash. Powering off = Yellow flash. Note that if you let go of the button too soon while powering off, the LEDs will flash white from the yellow they where at and go back to pairing mode. This is normal and fine, simply hold the power button for longer to power off. ○ Exiting sleep mode - After the controller hasn't been in use for some time it will go into sleep mode. If your LEDs are off and you have not powered the controller off and seen the yellow flash, your controller is in sleep mode. For some reason, **you cannot exit sleep mode by presssing the power button. Use any other button on the main face of the controller ("A" for example) to exit sleep mode.** Don't be like me and constantly factory reset the controller after connecting it to the Pi while trying to get out of sleep mode. ○ Factory reset - Hold power button for eight seconds. ○ Firmware update mode - Hold the power and the pairing buttons together until the LEDs flash yellow from a powered off state. Exit this mode by completing your firmware update, or press any other button on the main face of the controller ("A" for example). ○ Reset pairing information - Hold the pairing button until there is a single purple flash from a powered on state. **You must reset pairing information after changing modes if you have previously connected the controller in another mode, even if it's the same device.** ###Getting Started Guide **Charging** When you first receive your controller it *should* come charged out of the box, but this step is coming first in case it doesn't. You charge your controller via the micro-usb port and the included cable. Any standard phone charger is fine. When the controllers LEDs are blinking green, the controller is charging. Once the controller has finished charging, the controller will power on(?) and the LEDs will blink blue until the controller falls asleep, where as the LEDs will turn off.   **Updating Firmware** ###[NOTE] ~~Verison 1.69 of the NES30 Pro/FC30 Pro software currently breaks the controllers in the emulators. If you accidently updated to version 1.69 you can easily downgrade following the same steps but downloading the 1.68 version.~~ See comments, some people have 1.69 working, but I cannot confirm.### First download ~~the latest version of the download (V1.69 at time of writing)~~ version 1.68 (as version 1.69 seems to break the controllers in the emulators) from [8Bitdo's website.](http://www.8
