Independent developers have adapted Valve’s SteamOS ARM userland for selected Snapdragon gaming handhelds. These are community Linux projects, not Valve-supported Android releases, and each has its own device list and software components.
Which handhelds are on each project’s list?
The projects describe different support stages. SteamOS-ARM-SM8550 lists the AYN Odin 2 as tested, while SteamOS ARM for handhelds lists certain Snapdragon 8 Gen 3 devices as stable and a broader Snapdragon 8 Gen 2 group as pre-release beta.
| Project | Device and chip scope | Project-listed status | Software components |
| SteamOS-ARM-SM8550 | AYN Odin 2; Snapdragon 8 Gen 2 / SM8550 | AYN Odin 2: supported and tested. Retroid Pocket 6: partial issues. | SteamOS ARM userland; ROCKNIX ABL boot path; kernel attributed to SteamOS-Ubuntu. |
| SteamOS ARM for handhelds (SM8650) | Snapdragon 8 Gen 3 / SM8650: KONKR Pocket FIT and AYANEO Pocket S2 / S2 Pro. Its broader list also covers Snapdragon 8 Gen 2 / SM8550 devices. | v1.2: stable for the listed Gen 3 models. v1.3 beta 8: pre-release beta for the Gen 2 device group. | SteamOS ARM userland; kernel and device support attributed to ROCKNIX. |
| Holodor | AYN Odin 3 | Holodor lists an image as released on September 27, 2026. | Valve Holo Core userland with a ROCKNIX kernel. |
“Stable” is the SM8650 project’s label for its v1.2 release; the SM8550 project separately marks the AYN Odin 2 as tested. The same SteamOS ARM for handhelds project also published a v1.2.1 update addressing flicker below 1080p; our earlier coverage covers that release.
The userland, boot path and kernel differ
The userland is the system software that runs above the kernel. The projects pair SteamOS ARM userland with different lower-level components: SteamOS-ARM-SM8550 uses ROCKNIX ABL in its boot path and attributes its kernel to SteamOS-Ubuntu. The SM8650 project attributes its kernel and device support to ROCKNIX.
Holodor has a separate Odin 3 build
Holodor is a distinct project, rather than another branch of the SM8550 or SM8650 builds. Its project page lists an AYN Odin 3 image released on September 27, 2026, using Valve Holo Core userland with a ROCKNIX kernel.
Holodor estimates that heavy AAA games run at around 20–30 frames per second on its Odin 3 build. It also lists kernel-level anti-cheat as unsupported, along with limitations affecting overlays and some Unreal Engine 5 games.
What an earlier Odin 2 demonstration showed
A separate demonstration published on April 18, 2026, used an AYN Odin 2 with ROCKNIX nightly, Proton 11 and FEX, a layer that translates x86 instructions for ARM. Half-Life launched in that setup; Fable Anniversary had an audio issue, and the nightly build was described as experimental. Those observations belong to that demonstration, not the later repository builds.
