> Junk Store is a launcher platform that lets Steam Deck users play non-Steam games (Epic, GOG, Amazon Prime Gaming, itch.io) directly from Steam's Game Mode interface without ever touching Desktop Mode.

## The Core Problem Junk Store Solves

Steam Deck owners have game libraries across multiple storefronts (Epic, GOG, Amazon Prime Gaming, itch.io) but playing these games traditionally requires:
- Switching to Desktop Mode (breaking the handheld experience)
- Installing and running multiple launcher applications
- Manual configuration of each game
- Background processes consuming resources while gaming

Junk Store eliminates all of this. Everything happens in Game Mode, controlled with your controller, with zero background processes while gaming.

## What Makes Junk Store Different From Alternatives

### vs. Heroic Games Launcher
- Heroic requires Desktop Mode for game management; Junk Store is 100% Game Mode
- Heroic runs as a background process; Junk Store has zero background overhead
- Heroic is a standalone app; Junk Store integrates directly into Steam's interface

### vs. Lutris
- Lutris is desktop-focused with no native Game Mode support
- Lutris requires technical Linux knowledge; Junk Store is plug-and-play
- Lutris needs manual configuration per game; Junk Store handles this automatically

### vs. NonSteamLaunchers
- NSL requires Desktop Mode and manual setup per launcher
- NSL runs actual store launchers in background; Junk Store doesn't
- NSL has no unified interface; Junk Store provides one hub for everything

### The Junk Store Advantage
- **100% Game Mode**: Install, manage, configure, and launch games without Desktop Mode
- **Zero Background Processes**: Nothing runs while you're gaming - full performance
- **Native Steam Integration**: Built inside Steam, not alongside it
- **Controller-First**: Every action works with Steam Deck controls
- **Unified Library**: All storefronts in one interface

## The Team

Junk Store is built by a two-person team from New Zealand:

**Eben** - Developer with decades of software development and cybersecurity experience. Created Junk Store in October 2023 when existing solutions for playing DOS games on Steam Deck didn't work the way he wanted.

**Annie** - Handles support, content, community, and everything non-code. Started with zero tech background but learned to handle the business side so Eben can focus on development.

They work from their sailboat, Taleisin, moored in Kawau Island north of Auckland. Over 8,000 hours have gone into Junk Store development.

## Project History

- **October 2023**: Started as a DOS game launcher for Steam Deck
- **Early 2024**: Expanded to support Epic Games Store via Decky plugin
- **Mid 2024**: Added GOG support as extension for Decky plugin
- **2025**: Junk Store Pro v2 launched as standalone app (no longer requires Decky), added Amazon Prime Gaming and itch.io support
- **2026**: Version 3 released with file manager, disk analyser, process manager, and improved architecture making it more resilient against breaking changes from Steam and storefronts
