Jpod1003 · 26 Dec 2017, 21:25

@mediamogul yes it just says

Sorry - Raspbian/Debian Stretch (and newer) is not yet supported on the RPI

Distributor ID: Raspbian
Description: Raspbian GNU/Linux 9.3 (stretch)
Release: 9.3
Codename: stretch

You'll likely need to utilize a noobs installation that is older than Stretch (I.E. Jessie). As it states, Stretch isn't supported at the moment and there's currently no ETA.

@mediamogul Its already downloaded, so what do you suggest i do

mediamogul · 26 Dec 2017, 21:32

@jpod1003

If you haven't put a lot of time into your current installation, I'd recommend you start over with Jessie. Outside of that, you're gonna face an uphill battle even if you are able to get it installed, as the individual software components are not yet ready for Stretch.

@mediamogul I thought i was using jessie.

1.Also if skretch isn't supported. Then what do people usually use or what should i use then? and what will i need to do so/ how?

Also is there any other emulator that is supported?

Everyone except those working on adding Stretch support are currently using Jessie. As far as what you'll need for NOOBS, I believe it's just a matter of using the proper NOOBS image. Some people are discussing it here and the latest images are linked.

@mediamogul Im sorry but dont i already have raspbian installed? meaning i cant get jessie now.

mediamogul · 27 Dec 2017, 00:52

@jpod1003

Are you able to format and start over?

Jpod1003 · 27 Dec 2017, 02:00

@mediamogul Thanks for your help, so I guess all i need is a card reader, which comes with the kit and a flash drive?

And im just curious is there any other emulator for Raspbian or not really?

mediamogul · 27 Dec 2017, 02:17

@jpod1003

RetroPie is actually not an emulator, but rather a series of scripts and software to facilitate the installation and execution of a wide selection on individual emulators and ported games. Two alternatives that share a somewhat similar type of functionality that RetroPie offers for the Raspberry Pi are Recalbox and Lakka.

Jpod1003 · 27 Dec 2017, 02:23

@mediamogul and those i also cant get unless i re format. Can you link something maybe to tell me how to format and what i need?

mediamogul · 27 Dec 2017, 02:36

@jpod1003

I'm somewhat unfamiliar with NOOBS, but it exists to supposedly be simple, so I assume that after you've used it's setup process to install the Jesse image I linked to above, you could then use these instructions to install RetroPie on top. If you decide to simply flash the official RetroPie image found here, the information is detailed fully in the official RetroPie installation guide.

Jpod1003 · 27 Dec 2017, 02:47

@mediamogul Will i need to somehow uninstall raspbian before doing this or?

mediamogul · 27 Dec 2017, 02:51

@jpod1003

Flashing an official RetroPie image will overwrite anything already there. However, you may have to use your PC/Mac to format the SD card before starting over with NOOBS.

Jpod1003 · 27 Dec 2017, 02:53

@mediamogul Is there maybe a video on how to do this or something. And what do you mean start over with noobs?

mediamogul · 27 Dec 2017, 02:58

@jpod1003

Videos are often rife with inaccuracies and outdated information. The specifics of RetroPie change often enough to make them obsolete very quickly. It's always best to stick with the official documentation for everything. I've never installed anything with NOOBS before, so it could be that formatting the card might be necessary before starting over from scratch. You'll want to check their own official documentation to be sure.

Jpod1003 · 27 Dec 2017, 03:05

@mediamogul so there's nothing i can really use to know exactly what to do step by step?

mediamogul · 27 Dec 2017, 03:13

@jpod1003

If RetroPie is the only thing you're trying to put on your Pi, I would recommend the step-by-step instructions found in the RetroPie installation guide. After that, you'll be blasting centipedes and rescuing princesses in no time.

Jpod1003 · 27 Dec 2017, 03:21

@mediamogul Ok thanks for helping, So when i put the the retropie sd image on the MicroSD card and put it into the raspberry pi 3 it wont cause any corruptions or anything and it will just overwrite everything?

Also if i wanted in the future will i be able to add raspbian, and does it come with the image?

RetroPie is not it's own operating system and is actually installed on top of Raspbian already with the image you'll be using for the Raspberry Pi. To keep the overhead down, the RetroPie image makes use of Raspbian Lite, which is really only missing the desktop GUI that so many people associate with a standard operating system. However, the desktop environment can always be installed later from the RetroPie-Setup once everything's up and running.
