@simpleethat if you install raspbian(pixel) on pi4 in retropie setup, then configure on desktop then when your done just play in retropie, I play from desktop for now cos my kids use some cheats.
Use keyboard to exit since or add your menu and press twice, but be careful not to enter a menu and get stuck, it happen to me and I reset my settings, hehe.
I started with a 32GB which is plenty for Arcade Games ... as soon as you add consoles, well, i got a 64GB card which lasted a month before i got a RPI4 and was able to add even More Consoles .. picked up a 128GB card. Will see how long that lasts ;) ... prob end up using a hard drive for game next and just use a smaller SD Card for the Retropie OS
TLDR: SD Card Size will Depend on what systems/consoles you intend on playing.
Oh, and if you compress you roms/images (ie. i have compressed all my PS1 games to PBP format and Dreamcast/3DO/Sega Saturn games to CHD format ... saves a TON of space !)
When using the Libretro (RetroArch) input configuration, then yes, you can't have different auto-configs for each player. You can, however, using either a core input remap to change the mapping or use the MAME input configuration, which can be accessed by pressing Tab (you'll need a keyboard for this).
I want to add one thing to @BuZz' post: Please edit your post and give it a more explanatory topic. Imagine a forum filled with posts named "Newbie … Help!" and the like. Nobody wants to read every topic just to see what they are about.
Just a friendly advice. Welcome to Retropie and to this forum. :)
I have a similar issue:
Having 2 PS 3 controllers, yesterday I performed sudo apt-get update and sudo apt-get dist-upgrade.
After that, the controllers still paired, however auto-logon failed.
Then I chose to update all packages from the Retropie setup.
After that I rebooted, and then the controllers didn't pair anymore.
I will roll back to my last image, anyway I think some mess was being built into the latest update components. Obviously I'm not the only one having logon and controller pairing issues after the recent updates...
Also can anyone recommend what would be the best wired, USB or Bluetooth controllers to use buy, there are so many out there and do not want to buy one that does not work well.
I got this iNexxt SNES type gamepad. They are about 9€ a piece, less for a bundle of two. I had one ghost click so far (in about two weeks of use) but for the price it’s a very nice controller. Feels very much like an actual SNES controller. Both of them worked perfectly, were immedately recognised by Retropie and very easy to set up.
