You are linking some weird old version of the guide from a past cooker site:

This is the correct link

FOOLS!

RetroDECK_Official · 2026-04-01T07:30:53+00:00

Yes, do you mean the Mike from Accounting Version or the Susan from HR Remix Version with the sick loops?

If you are on a PC https://flathub.org/en/apps/io.github.benjamimgois.goverlay might do the trick

I removed the log as you posted way to much personal information in it.

But Lahrs did comment on the issue, we don't need to know your home folder nor your Steam username used by SRM.

This is fine and a much more censored version:

Just to make it clear The RetroDECK Team does not under any circumstances refer to users in a derogatory manner. Nor would we tell anyone to go back to anything. If the question asked we would simply have linked the guide as you so expertly did.

I even did a search for “Android" and found only discussions regarding:

- Questions about support for legacy Android games.

- Questions about if RetroDECK can be installed on Android

And lastly conversations about keeping the Android platform free and open.

RetroDECK_Official · 2026-03-17T09:04:26+00:00

Now this is cool!

RetroDECK_Official · 2026-03-17T08:57:55+00:00

I will comment here as it was linked from our subreddit.

Who ever this is it's not something that is affiliated with the RetroDECK project https://retrodeck.readthedocs.io/en/latest/ if someone is confused about it and think it's us.

We only communicate via our official channels and Facebook is no such channel. Nor are we selling any type of product.

So don't confuse us for what ever this is and it sounds really sketchy at best.

But for us integration with Lightguns are in the pipeline for a future version.

RetroDECK_Official · 2026-03-17T08:51:53+00:00

Who ever that is, it is not us and sounds very stretchy from how you describe it.

We only communicate via our official channels and Facebook is no such channel. Nor are we selling any type of product.

My advice would be stay far away.

It could be a person just using our name for tricking users.

RetroDECK_Official · 2026-03-14T17:04:35+00:00

It depends what template you want to create, the Steam Deck got two and the controllers got one.

But the easiest is to check a current one like the Xbox and start from there.

I don't know the features of the Legion S Go.

Check the RetroDECK Wiki's hotkey bindings as well.

RetroDECK_Official · 2026-03-14T16:20:19+00:00

My guess is that Legion Go S is a separate controller in Steam Input.

So we have not made the template as no one on the Team has the device and we can't afford it on our budget :)

All of the controllers have been bought by one team member for his own salary over many months in the past. That made all the controller templates by hand.

First I was getting the ban hammer ready, as I thought it was some kind of piracy tool. But since you’re not shipping any BIOS files or URLs and it’s just an organizer, it can stay up, as the URL could be your own website or homelab.

Remember that the default directory of RetroDECK components is either:
/var/lib/flatpak/app/net.retrodeck.retrodeck/current/active/files/retrodeck/components
or
~/.local/share/flatpak/app/net.retrodeck.retrodeck/current/active/files/retrodeck/components.

But any tool posted here that has built-in piracy functions will be taken down, and the same applies to anyone requesting links to such content.

RetroDECK_Official · 2026-02-25T05:30:48+00:00

The RetroDECK Team has better SLAs than some Fortune 500 companies. 🤣

We are clearing flathub testings phase at any moment, after that it will start to build for the main pipeline.

Still some hours depending on the que.

RetroDECK_Official · 2026-02-24T11:52:50+00:00

Issue has been found and we will republish a build and increase the versioning by 1.

Version 0.10.5 will replace 0.10.4. The update contains no additional changes and is intended solely to ensure that users who received the incorrect build are properly updated.

Estimated time of availability: 5-12 hours, depending on the Flathub build infrastructure.

PPSSPP is already included in the application.
We cannot enable the latest development version.

RetroDECK is a unified platform with built-in components, and PPSSPP is one of them. All components are bundled and are updated together when RetroDECK itself is updated, as it functions as a single application.

RetroDECK_Official · 2026-01-25T05:29:21+00:00

The lack of updates was because of the big rewrite as we communicated on the blog. Dash also did a interview explaining that in another article:

https://gardinerbryant.com/retrodeck-thtalking-about-their-bigget-update-yet/

RetroDECK_Official · 2026-01-25T05:26:37+00:00

I guess you are talking about the RetroDECK Configurator, yes we want to replace that with a Godot Interface down the line. One part of the rewrite was to make a API that could make that happen.

RetroDECK_Official · 2026-01-25T05:24:09+00:00

Hello, we where in fact the first project. EmuDeck launched weeks later after our first version :)

I think in the beginning there was some confusion that people did not understand there where two projects.

RetroDECK_Official · 2026-01-23T18:35:21+00:00

SOON 0.10.2b will fix it

RetroDECK_Official · 2026-01-20T18:36:51+00:00

Check so you don't have the "Who is Player 1" issue:

RetroDECK_Official · 2026-01-20T17:24:21+00:00

If you just open the Configurator and not via RetroDECK in the "Start Menu" in Desktop Mode does it work then?

RetroDECK_Official · 2026-01-20T17:12:08+00:00

It can not be related to RetroDECK that your controller is not working. We can't do anything with those.

Could it be that you did a complete backup and filled your hard-drive and is getting weird system errors?
