How do i install it?

@Omay said in Jack of all trades controller needs:

What buttons would I need to be able to run just about any game that RetroPie supports?

Supporting 'any' game is a tall order, since imitating a PS1/Xbox style controller may not work so well with a cabinet style panel - operating 2 joysticks for 3d game while at the same time having to push buttons is a bit cumbersome.

For an arcade style cabinet you may want to use a traditional arcade cabinet with an analog joystick + 6 buttons for actions (A/B/X/Y + LT/RT) + 2 buttons for Start/Select. Optionally, you may want to add a separate button for the 'Hotkey Enable' button used by most libretro emulator - that one can function also as a 'Menu' or 'Exit' button for other (non-libretro) emulators.

You can also use an external (Wired/Wireless) gamepad for more modern games - i.e. PS1/Dreamcast games which require a joystick + D-Pad.

@mitu I'm stupid. Somehow turbo mode was on and that's why there was no sound.
Sideloading the built-in SDL library doesn't help. But I'll set the export thing in the redream script. The underruns don't seem to affect the gameplay otherwise...
Anyway thanks for the help! Another little quirk is gone from my list. :D

@Tango The welcome logo is installed by default on any image, but can be un-installed afterwards. It's a separate package that doesn't affect everything else.

@sleve_mcdichael Oh, I see! God I feel an idiot haha .. I'll try that out, but that makes sense.

@mitu That did the trick! The keyboard now works in ScummVM. Thank you for your insight and expertise!

@mitu Alright, that sucks to hear but guess i'll get to fixing it the physical way then. Thank you for the responses!

@mitu The price of 11.90 € / 10.46 £ seems reasonable. Order is placed and it’s on its way to me now. Thanks for the recommendation!

Welcome to the RetroPie forum :)

Sounds like an ambitious project.

For the peripherals: You will most likely need to use a analog to digital converter as the Raspberry Pi does not have one built-in. An external MCP3008 can handle up to eight analog inputs (and you can use up to two MCP3008 on an Raspberry Pi). This repo [1] contains an example on how to use an MCP3008, additionally you should enable SPI on the Raspberry Pi [2].

The sources (pedals, aso,) should be able to be run with 3.3V, as this is the allowed logic level for the GPIO. If they have to be do run at higher voltages you will need a level-shifter [3], for example BSS138 MOSFETs are suitable for this. If you apply more than 3.3V to the GPIO logic gates it may damage the Pi.

For the SBC: If you have a Libre Potato already you can start with it for the prototyping with the peripherals (see above). Howerver, the GPIO pinout is not compatible to the Raspberry Pi 3 or 4. Thus it will include remapping when you switch to an Raspberry Pi.

As this is your first project I would refrain from using a different board than a Raspberry Pi, to reduce complexity. Although a Pi has a higher price than a Libre it will save you worries, head-banging and tinkering time in the long run. I do not own a Libre but I read the GPU is proprietary (Mali 450), also Libre Computing does not provide a Debian Buster (RaspiOS 10) image (only Bullseye, RaspiOS 11). [4]
Currently RetroPie uses Buster as OS, Bullseye support is in the works. This means: You will have to adapt the RetroPie-Scripts and esp. GPU related configuration by yourself when you run a Bullseye RaspiOS + RetroPie scripts on the Libre. Plus the usage of a libre computer is at best a niche in this forum, i.e. expect little to no support. If you can afford it head for a Raspberry Pi 4 (2GB is sufficient) as it has enough performance to run racing simulations with theses systems: Sega Saturn, Sega Dreamcast, Playstation 1 and earlier consoles/home computers. However, emulating Nintendo Wii and Playstation 2 games is not possible (Running Nintendo DS games smoothly is a hit-and-miss).

@lostless - Thanks!

Didn't realize that each USB port would have a priority, I thought it was assigned from Emulation Station. Moved the USB cords around, and now I'm back up and running.

@duglor said in Controller not working as Kempston for Spectrum Games:

Excellent. Does that mean it's in the latest binary update or source update? or not yet?

You may now update via binary or source and should receive changelist 847dbbd (or later if any new changes come in).

You can verify this after you update by selecting "Package version information" and noting the long "Commit" number (should start with 847dbbd)

@mitu
I wanted to play in a docker container because I can't install Retropie on Debian 11, and I didn't want to buy another sd card only for testing , but It seems it will be the best way...
Thanks for your support, best regards 🤗

@duglor

Just use hypseus, save yourself the headache.

I had the same idea, I am trying to run RetroPie on my Raspberry Pi with Debian 11 (I can't install RetroPie on Bullseye) on a Docker container, and I am using my iPad as a screen through Remote Desktop, and a Bluetooth controller (8Bitdo Zero 2), and I can use Emulationstation (my gamepad works fine there) but when I launch any game my controller doesn't work (I don't have a wired controller so I don't know if that's the problem). I've tried to change the retroarch controller configuration and changing it to "sdl2" only works one button... I don't know why. If you don't have any issues maybe I could try your Dockerfile because it might be my setup?

Are both controller working properly when only one of them is connected ? What kind of controllers are you using ?
Can you add some more info about your setup, as requested in https://retropie.org.uk/forum/topic/3/read-this-first ? Fill in the info you know, especially the info about the controllers, Pi model (if it's the case) and emulator used.

@Griz952 said in [Solved] Activate Second Controller:

Performance is not great, ...

You can give lzdoom (standalone Doom port) a try, it has controller support, though you may need a keyboard to set it up. Haven't used it with a controller, but it may have better performance.

i found out what to do, with esc of keyboard i open the menu of emulator and there i can config

thanks
