I turned off what a handheld doesn't need and fixed the rest, the long version is in [HOW-IT-WORKS.md](docs/HOW-IT-WORKS.md). What you get: - Game Mode and Desktop Mode, with the controller showing up as a Steam Deck pad - x86 PC games through FEX and ARM64 Proton, plus Epic, GOG and Amazon through Heroic - Android apps with the Play Store, and Restart into Android from Handheld Control - Updates from Settings > System, no reflashing - Install to internal storage next to Android, or keep it on a microSD card - Game Mode on an external monitor or dock, sound included - Lossless Scaling frame gen (lsfg-vk 2.0 and Classic 1.x), Decky and the performance overlay - Steam Remote Play with hardware decoding, plus optional PyroWave - Loadout, which installs emulators and apps picked for your SoC - Sleep that lasts, quiet fan curves, and a clean power off before the battery runs flat - A dashboard with themes on the bottom screen of the AYN Thor and AYANEO Pocket DS ## Quick start 1. Flash the OpenABL bootloader for your SoC (ROCKNIX ABL works too), the [ABL guide](https://steamos-arm-port.github.io/getting-started/abl/) walks you through it. Back up your stock ABL first. 2. Download the image for your SoC from [Releases](https://github.com/hashtagbasit/SteamOS-ARM-Port/releases/latest), open the `.001` part with 7-Zip and flash the `.img` inside to a microSD card (32 GB+) with balenaEtcher or Rufus. 3. Boot the card from the ABL menu and pick your device. First boot takes a couple of minutes. Already on it? Go to Settings > System > Check for updates. ## Devices ### Handhelds | SoC | Devices | Status | |---|---|---| | Snapdragon 8 Elite | AYN Odin 3, KONKR Pocket FIT Elite | Stable | | Snapdragon 8 Gen 3 | KONKR Pocket FIT, AYANEO Pocket S2 / S2 Pro | Stable | | Snapdragon 8 Gen 2 | AYN Odin 2 / Mini / Portal / Thor, AYANEO Pocket ACE / DMG / DS / EVO / S 1K / S 2K, Retroid Pocket 6 / Nova | Stable | | Snapdragon 865 | Retroid Pocket 5 / Flip 2 / Mini / Mini V2, AYN Thor Lite, MANGMI Air Y Pro / Pocket Max, AYANEO Pocket MICRO 2 | Beta | There's one image per SoC, you pick your device in the ABL menu and it sets itself up.
