The Retropie thread - use a Raspberry Pi for the ultimate under-the-TV emulation station!


Recommended Posts

I know the Retropie is covered in other threads, but I still think it is still deserving of a thread of its own so here goes.  However, due to only having a Pi starter kit for just over a week, and in part because of a lack of time and a bit of laziness when I am free, I haven't managed to write up one of those forum standard, really helpful opening posts with a guide, tips, handy links, etc.  However, swooping in to save the day is @Mr. Gerbik who has does some excellent work and thrown together a shit-ton of useful information below in post nine below.  :hat:

 

Anyway, what display settings would people recommend for SNES, NES, MD, GBA, Neo-Geo, and MAME games on my Samsung UE50JU6800?

 

Thanks in advance.

When I installed my RetroPie I just quickly fumbled through. I will post about the issues I encountered when I have the time  (finding the overscan option to get rid of the black borders for example) and my own settings so that smarter forumites can point out all the mistakes.

 

I'll also include links and tutorials and stuff that you can copy paste to the op. 

 

Great idea for a thread btw :) RetroPie deserves it, it's awesome and yet so tiny. Love it :wub:

Excellent, that is exactly what the opening post needed, but with having one for less than a week I'm still quite uninformed about it all!  Cheers.

 

I'd be interested to hear which splash screens and ES themes people are using too.  I hate massive lists of games that I'll never play to scroll through, but I'm tempted to pick up a 128gb card just to try Rey's Attract Mode image.  It sounds amazing.

I only received my PI 3 starter kit last week and I am still tinkering with it.  What display settings would people recommend for SNES, NES, MD, GBA, Neo-Geo, and MAME games on my Samsung UE50JU6800?

 

If you have a 1080p TV then to retain 1:1 pixel scaling for the best image quality there are two options.

 

4x scaling - This will be a minimally bordered image for systems on a 1080p TV, but it's as big as you can get without losing any picture.

5x scaling - This will fill the whole vertical frame of your TV but it will chop off some of the image. Luckily the portion of the image that gets cut off is considered part of the overscan area, so most games that consider the safe zone will have been built around the assumption that that portion of the image may be missing (ie. not sticking UI elements or important things there).

 

With those 1:1 scaling options you'll be able to use shaders much easier without strange artefacts. The best CRT shader for the Pi is a specially built one called CRT-Pi (which is built into Retroarch/Retropie), which maintains full speed at 1080p.

Worth mentioning too that if you use an Xbox 360 pad, either wired or wireless, then you should navigate to the Retropie Setup menu and install the drivers for it. Otherwise it won't function correctly with everything.

I had no idea - and also never encountered any issues tbh. Not yet anyway. I'll add it to the post!

I think the only real issue (with a wired pad, anyway) is some emulators not seeing the right analogue stick as analogue, and possibly the triggers not being analogue either. The drivers fix that.

Cheers! Will have to fix that in my own RetroPie asap.

 

Hey @Stejay! The post is finished, you can copy it to your opening post! Feel free to correct any mistakes and add whatever you see fit. Or simply change everything :)

Retroarch is a frontend for running libretro api based emulators (basically emulators packaged up as DLL files). Essentially it's a multi machine emulator.

 

It has its own GUI (A basic one, and one heavily influenced by the PlayStation UI) or can be booted directly from the command line.

 

Emulation Station and Attract Mode are frontends for Retroarch and other more standard emulators, which means they can cover more games as not every system is in Retroarch.
