steamtinkerlaunch VS winesapOS

You probably mean SteamTinkerLaunch

I've tried all of the known methods, the one using bottles:https://github.com/thesupersonic16/HedgeModManager/wiki/Running-on-Linux-(Wine), the one using Steamtinkerlaunch: https://github.com/sonic2kk/steamtinkerlaunch/wiki/Hedge-Mod-Manager and the one that used to work but doesn't anymore:https://linuxgamingcentral.com/posts/updated-sonic-frontiers-steam-deck-modding-guide/ The bottles method worked a few weeks ago (although a lot of codes and mods didn't work) but doesn't seem to work anymore, the program doesn't seem to recognize the .yml configuration file provided in the guide anymore, I even tried installing the dependencies manually but the game (Sonic Frontiers) doesn't load the mod loader (the game launches but without mods), perhaps bottles doesn't use .yml files anymore ? The Steamtinkerlaunch method using Proton 7.0 also manages to install hedgemodmanager but once the mod loader is installed the game simply won't launch (I even tried providing mscore.dll but doesn't seem to make a difference). The method detailed on linuxgamingcentral.com used to work but now doesn't anymore, probably because steamtinkerlaunch now also tries to install .net 40 and .net 48. I get an error along the lines of "error, couldn't load mscore.dll to display the correct error message, please reinstall. Net". I'm losing my mind over this. Does anyone of you have hedgemodmanager working on Steam Deck ? If so how did you do it ?

Or maybe Steam Tinker launch (if using steam): https://github.com/sonic2kk/steamtinkerlaunch

This, right? This results in the following error:

Hey. I'm currently trying to get LiveSplit to run in the same Proton instance as a game (so I have the autosplitter available). I've managed to get that working by using SteamTinkerLaunch (https://github.com/sonic2kk/steamtinkerlaunch/wiki)

Click "Add Version", then install the latest SteamTinkerLaunch

Make sure to check the wiki on GitHub. It has a page for troubleshooting and the second entry sounds like your problem.

I recently had a nice discussion with the STL dev (steamtinkerlaunch#813). This might give you also a bit of insight.

There's steamtinkerlaunch for vortex/modorganizer there's also protontricks to mess around with each game proton prefix and etc. You'll have to Google these to get a better explanation but these are just the options I know of.

I run winesapOS[0] which is based on SteamOS and was able to repurpose an old Toshiba notebook for my kids, running Freddy Fish* and other games. Windows 10 doesn't run smoothly (even though it came with Windows 10) and I'm not going to run anything older than that.

* Yes, ScummVM is available for Linux but the Steam Linux distribution included an old ScummVM which wasn't able to load some libraries. Running the Windows version through an compatibility layer was easier than modifying shell files to run the latest ScummVM through flatpak.

HoloISO and ChimeraOS no longer support Nvidia so you'll need to use winesapOS.

If the BIOS isn't locked try booting winesapOS off a flash drive.

Context: winesap seems to be a spin of SteamOS3 with KDE, somehow optimised for gaming. It's meant to be used as a live distro?

My understanding is that Valve intends to release SteamOS 3 for install on other machines at some point, and it will likely include support when that happens. In the meantime, there a modified version of it available on GitHub here which claims to support NVIDIA GPUs, but I have not tried it.

Unofficial SteamOS 3.0 (steam deck) build for PCs, with a graphical installer

Currently I am planning on running a VM with winsapeos

https://github.com/LukeShortCloud/winesapOS - it is a simple image, ready made, with a lot of software installed. There is almost no configuration needed. However, this means that the image will contain a lot of software that you don't need. From a gaming perspective, you could even game on this and it's already set up - but as it is running from a SD card, I prefer to just reboot into the standard OS.

If you want something similar to HoloISO, but it has everything you need out of the box, there is WinesapOS. It is also based on the Steam recovery image, but with a bunch of apps and changes for desktop gamers. For an advanced user it would be too bloated, but for a beginner it means you will not need to install or setup apps for any of your game launchers, antivirus software, Chrome, Wine, etc. It also features Intel Mac support, which is pretty cool.
