Dooble Boot Raspbian / RetroPie

najaru

@meleu i Can do the method 1, i have a Ubuntu PC.
But It seems that i Will install a new image system on external device (like a standalone Ubuntu on a usb key)......
If i do this method, i Will not erase the preinstalled OS in microSD?

@meleu I've followed nr 2 now, but how do i actually boot into retropie? I try to type "emulationstation" in the command line but i get this error:
X is running. Please shut down X in order to mitigate problems with losing keyboard input. For example, logout from LXDE.
So how do i launch retropie when i also have Raspbian?

Did you try to exit LXDE and type emulationstation again? :)

Actually you have to decide what do you want to see when you turn on your Raspberry Pi. If you want to enter directly on emulationstation, then it's better to enable autologin, etc. The simplest way I know how to do it is using the raspi-config utility.

After doing this you should run retropie_setup and then Configuration / tools -> autostart.

Yes, you'll do. If you really need the preinstalled OS, then you should go with the method 2. ;-)

Remember: the OS on the RetroPie image is an actual Raspbian. I have my doubts if you really need the preinstalled OS.

@meleu I've buyed a preinstalled RaspeberryPi kit , then it will arrived with microSD with NOOBS inside

I want to preserve a clean system (to use it lika a micro PC for simple operations.
Maybe is better to use a separate SD card? and installing on it the RetroPi?

Well, a 32GB microSD card isn't that expensive... Then, yes, use a separate SD card is reasonable solution.

@meleu perfect thaks for your help

and the emulationstation is included in retropie? i hav'nt still understand the Raspbian-NOOBS-retropie-emulationstation structure......

@najaru By the way, when I bought my first Raspberry Pi (2013) I thought exactly like you (preserve the original preinstalled OS on the SD). Months later I realized that I never touched that SD card and then formated it and started using on my Android phone. :-)

and the emulationstation is included in retropie?

yes.

i hav'nt still understand the Raspbian-NOOBS-retropie-emulationstation structure

A quick, dirty, incomplete and short description could be...

Raspbian: the Operating System (a Debian Linux optimized for Raspberry Pi).

emulationstation: the frontend that we currently use to show the available games and console-systems. It actually does nothing more than creating a pretty menu to select your game of choice.

RetroArch: is a frontend to the libretro API, but putting in simple words, it is the system that runs most of the emulators here. They are used to call their emulators as "libretro cores" or simply "core". I know, I know... it's little confusing at first, but you'll get used after some time. :-)

RetroPie-Setup: is a bunch of bash scripts, and form the core of the RetroPie system. It is the glue that makes other programs such as emulationstation and RetroArch work together nicely.

The wiki will help you a lot. And there are some cool videos about RetroPie on youtube. They can help you to understand/deal with all this stuff. Search for RetroPie there and prefer videos from Herb Fargus, Floob and Tech Tipsta.
