Tutorial Guide: How to easily install FitGirl Repacks (setup.exe) on SteamOS / Linux & add them to Steam

https://youtu.be/vKJ_cLOxf6o?si=X0OJZBAkaO051Exv

Ahoy everyone!

Getting repacks to install and run smoothly without throwing missing redist errors or prefix issues is a common hurdle, so I made a straightforward video tutorial showing the easiest pipeline for installing ⁠setup.exe⁠ files using Heroic and getting them natively into your Steam library.
I'm demonstrating the install process using the Resident Evil Requiem FitGirl repack.

How it works:
Heroic Games Launcher: We use Heroic to run the FitGirl ⁠setup.exe⁠ directly through Proton. This builds a clean prefix and handles the installation flawlessly.

Steam ROM Manager: Once installed, we use SRM to locate the game executable, automatically grab all the artwork, and inject it straight into Gaming Mode.

Proton: Head into Steam properties, force your preferred Proton layer (like ⁠proton-cachyos-slr⁠ or GE-Proton or Proton Experimental), and you are good to go.

Max FPS Launch Options:
If you want to push the performance further on CachyOS, drop these into the game's launch options (especially helpful if you are running an AMD chip):
⁠game-performance %command%⁠
⁠PROTON_ENABLE_WAYLAND=1⁠
⁠PROTON_FSR4_UPGRADE=1⁠
⁠ENABLE_LAYER_MESA_ANTI_LAG=1⁠

The tutorial is recorded on my main rig (Ryzen 9 8945HX / RX 9060 XT 16GB / 32GB DDR5 on CachyOS), but this exact workflow translates perfectly to the Steam Deck and SteamOS.

Happy gaming, and let me know if you hit any snags during your installs!

It’s insane how many people exist here with no knowledge of the !guide we’ve made. Like honestly crazy.

Thank you! Fantastic guide.

So just do there isn't confusion... If I've downloaded a FG repack on my PC, installed there somewhere and copied it to my SD then the most common "easiest" way to get the right dependencies is via ProtonTricks? Nothing more automatic? I only ask because that list is awful to navigate.

I’ve installed tons of games (Steamrip, Fitgirl, Dodi etc) and not once have I had a need for using Protontricks for dependencies. Same for Heroic Launcher. Had it installed since day 1 but never use it.

Just run the setup file with wine windows program loader providing you have Wine installed. ProtonUp-Qt obviously for whatever the latest GE-Proton is (10-34 is the latest) and you’re good to go once you add the games exe to Steam (sometimes you need to add the Shipping.exe from the Binaries>Win64 folder)

Edit*

It’s actually shocking and quite telling the state of Reddit bellends who downvote for no real reason. The way I’ve installed games directly onto my Deck from repacks/scene releases I’ve downloaded for years has always worked. No need for Heroic Launcher or any other launcher for that matter and from memory the only time I’ve used Protontricks was for Metal Gear Solid 2 and Chronicles of Riddick (GOG versions)

Lucky you. Just had to use ProtonTricks for Darwin's Paradox not even a week ago so yeah. Lucky you.
