How to Install Junk Store Pro with the Installer

Press the Steam button, then Power, then Switch to Desktop.

Go to the portal and sign in. If you have forgotten your password, the login page has a reset option. Make sure you check your spam folder if it doesn't show in your inbox.

On Junk Store Pro Files, the green Download Installer button under Quick Install is the one you want. Ignore the list of builds underneath it. Those are for installing manually, and the installer fetches the right build for you anyway.

It's a tiny file, a couple of hundred bytes, so the download is instant.

Open Dolphin, go to Downloads, and drag the file onto your Desktop. It shows up as Install JunkStore with an orange warning badge on the icon, which is normal for a file that hasn't been run yet.

KDE asks whether you trust the program before it runs. Press Continue.

If double-clicking does nothing, or opens the file in a text editor, right-click it and choose Properties, then Permissions, and tick the box to allow executing the file as a program.

The installer opens with a login window of its own. Use the same email and password as the portal.

This sign-in carries through, so you won't be asked to sign in to Junk Store Pro again when you get back to Game Mode.

Both channels default to stable, which is generally the one almost everyone will want on first install.

Nothing here is permanent. The channels are the same settings you'll find later in Junk Store Pro under Settings, so you can change your mind.

The two tickboxes

These are worth understanding rather than clicking past, because the first one decides which clients fetch and install your games.

Install flatpaks (dependencies) installs the legacy flatpak clients: Legendary for Epic, gogdl for GOG and nile for Amazon. It arrives ticked, so leaving the dialogue alone gives you these.

Install emulators adds the emulator flatpaks, for running retro and emulated games through Junk Store Pro. It arrives unticked. Tick it only if you're planning to use them, since it's a fair bit of extra software to put on your Deck otherwise.

The new clients

We've built our own clients for Epic, GOG and Amazon, the same way we did for itch. They're faster than the legacy clients, and they're the only way to use more than one account with the same store.

To use them, untick Install flatpaks. They aren't the default yet, so this route costs you one small step in Game Mode, which has to be done before you sign in to any store. It's covered in step 10 below, and it's a single switch per store.

There's one trade-off. The experimental cloud saves don't work with the new clients. If you're relying on those, stay on the legacy clients and leave the tickbox as it is.

So the choice is between leaving the default alone and having it work straight away, or unticking and doing one extra thing for faster, multi-account clients.

You're not stuck with whichever you pick. If you take the default now and fancy the new clients later, that's fine, and there's nothing to reinstall. Switching to the new clients covers it in a few steps.

Default: flatpaks ticked. The legacy clients. Nothing extra to do later.

Nothing ticked: the new clients. Faster, and multiple accounts per store. Needs the switch in step 10 before you sign in.

Both ticked: legacy clients plus emulators. The default, with the emulator flatpaks added.

Press Next.

This is the part that does the work. It fetches the build, downloads it, then runs the install, and shows you what it's doing as it goes. There's nothing to press.

When it's done it moves itself on to step 3.

Tick the stores you want and press Generate. The installer creates the tabs for you, which is the step you'd otherwise be doing by hand later.

You can press Skip and set them up yourself later if you'd rather. That means going through the Generator by hand: downloading the presets, then generating each store you want.

"Installation Complete" comes up once the stores have been generated, so it's the last thing you see rather than something that appears part way through. Once it's on screen you're finished in Desktop Mode, and you're safe to press Close.

Return to Game Mode and tap SELECT to open Junk Store Pro. That's the button above the D-pad, the one Steam labels View. On a PC, Ctrl+3 does the same thing.

Your tabs are already there, one for each store you generated.

The new clients are installed, but the stores don't use them until you say so. Use Legacy Clients is that switch, and there's one per store, so repeat this on each tab you generated.

It lives on the store's own settings, which you get to from the cog at the top of the tab. It's in the row of buttons to the right of the search box, between the sliders and the shop icon.

Sliders and cog mean the same thing throughout Junk Store Pro: sliders are actions that happen, the cog is settings that stay. You want the cog.

Open it and scroll to the bottom of Advanced.

On, it looks like this. This is the one you don't want:

Tap it so it reads Off:

That's it. Because you're doing this on a fresh install, before signing in, there's nothing cached to clear and no library to rebuild. Do it on each store, then carry on to signing in.

Open each tab and sign in to the store itself. The library fills in from there.

Give it a few minutes. The first sync builds a database for each store, so a large library takes a while to appear. Nothing is wrong if a tab sits empty at first.
