Valve’s Codename Fremont, a Console Explored & Explained - HLX Files Gaiden

| Summary status | complete |

Overview

This Gaiden episode recaps the earlier “Galileo” Steam Deck hardware datamine and presents newly found references to a device codenamed Fremont. Tyler describes a public mirror of Valve’s SteamOS and Steam Deck GitLab repositories, called “evav” in the transcript, where commits reference an AMD “Lilac” APU, a prototype board codenamed F7F, a full-sized HDMI-A port, and an HDMI CEC endpoint. He treats the datamined identifiers as factual evidence but frames the conclusion that Fremont is a living-room Steam console as an assumption. The video contains no Half-Life 3-specific information; Half-Life: Alyx appears only in the recap of a Valve employee’s photographs.

Mentioned events

Galileo firmware datamine and proximity-sensing power button

• Description: Tyler recaps a Steam Deck firmware release datamined by Brad Lynch (SadlyItsBradley) and a second dataminer the transcript renders as “Fox.” The firmware referenced new hardware called Galileo with functions similar to a television-based box, including a proximity-sensing, touch-sensitive, lit power button or power ring.
• Confidence: Fact — the claim is attributed to specific firmware datamining by named dataminers; Tyler presents it as established findings.
• Category: Hardware
• Source: Datamine of Steam Deck firmware by Brad Lynch and “Fox.”
• Earlier mentions: References the channel’s earlier video from “last year” about a Steam Deck-style TV console; the Galileo firmware and power-button claims are recapped, with the Fremont datamine added.
• Verification: needs follow-up — check archived Steam Deck firmware and the evav mirror for Galileo identifiers and the proximity power-button implementation.

Valve patent for a touch- and proximity-sensing power button

• Description: According to Tyler, a member of Valve’s Steam Hardware team filed a patent specifically for a touch-sensing, proximity-sensing, lit power button. No patent number, inventor name, or filing date is given.
• Confidence: Fact — Tyler states a patent filing as a concrete artifact, though the document itself is not shown or named.
• Category: Hardware
• Source: Valve patent filing, as described by Tyler.
• Earlier mentions: None identified in this video.
• Verification: needs follow-up — locate the patent by applicant Valve and by power-button/proximity-sensing claims to confirm inventor and date.

Valve employee’s photos of a box with the same power button

• Description: In the lead-up to Half-Life: Alyx, Valve’s Jeff Keeley (spelling per transcript) posted pictures and videos of himself playing Half-Life: Alyx with a box that had a lit, proximity-sensing, touch-sensitive power button. Tyler identifies this as the hardware then called Galileo.
• Confidence: Fact — Tyler points to photographs and videos as the evidence.
• Category: Hardware
• Source: Photographs and videos posted by Valve hardware team member Jeff Keeley.
• Earlier mentions: None identified in this video.
• Verification: needs follow-up — locate the original posts and confirm the device and the power-button detail.

Galileo reinterpreted as a TV console rather than a VR streaming box

• Description: Tyler says Galileo at the time seemed more related to a separate box that would wirelessly stream VR games to the Deckard headset, but that the device is now effectively understood as a console plugged into a television and used with a controller, running the same software as the Steam Deck.
• Confidence: Speculation — Tyler’s interpretation of the datamined firmware, with no new artifact cited for the reinterpretation.
• Category: Hardware
• Source: Tyler’s analysis of the Galileo firmware datamine.
• Earlier mentions: Builds on the channel’s earlier Galileo coverage but does not cite a new source for the changed interpretation.
• Verification: needs follow-up — additional firmware or commit evidence linking Galileo to television output rather than VR streaming.

Fremont hardware and the AMD “Lilac” APU

• Description: New information found “about a week ago” describes hardware codenamed Fremont running a far more powerful AMD APU than the Steam Deck’s. The APU is codenamed Lilac; Tyler explains that an APU combines a CPU and GPU on one chip. He calls Lilac an unknown processor that is “far and away” more powerful than anything currently in the Steam Deck.
• Confidence: Fact — the Fremont and Lilac names come from the cited datamine; the performance characterization is Tyler’s inference from the codename being a newer, distinct part.
• Category: Hardware
• Source: Datamine of the evav mirror of Valve’s SteamOS and Steam Deck GitLab repositories.
• Earlier mentions: None identified in this video.
• Verification: needs follow-up — PCI IDs, kernel patches, or benchmark entries identifying Lilac’s architecture and specifications.

Pre-Steam Deck testing on the AMD “Picasso” APU

• Description: Tyler notes that, for the longest time before the Steam Deck, most testing was done on a separate test board running an AMD APU codenamed Picasso, presented as historical context for Valve’s practice of testing on codenamed prototype boards.
• Confidence: Fact — presented as known historical references, though no specific document is named.
• Category: Hardware
• Source: Known historical references from Steam Deck-era hardware datamining, as described by Tyler.
• Earlier mentions: None identified in this video.
• Verification: needs follow-up — locate the original Picasso test-board references in Valve-linked repositories or driver patches.

The “evav” Valve repository mirror as a datamining source

• Description: Tyler introduces “evav” (spelling per transcript), which self-describes as the “unofficial Valve public mirror maintained until Valve publicizes their private SteamOS and Steam Deck GitLab repositories.” He compares mining it to using the SteamDB diff checker, and says it exposes hardware-related development and QA activity.
• Confidence: Fact — the mirror’s self-description and the commits are the cited artifacts.
• Category: Technology
• Source: The evav mirror’s own description and commit history.
• Earlier mentions: None identified in this video.
• Verification: needs follow-up — inspect the evav repository and its commit log directly for the cited changes.

QA testing by “Quant Computing” on the F7F board

• Description: Tyler says quality assurance testing on the device was done by a company the transcript calls “Quant Computing,” and that Valve brought the debug changes into the repository. The changes reference the AMD Lilac APU running on a prototype board codenamed F7F.
• Confidence: Fact — specific commit and debug-change references are cited, though the company name is given only as heard in the transcript.
• Category: Development state
• Source: Commit and debug-change entries in the evav mirror.
• Earlier mentions: None identified in this video.
• Verification: needs follow-up — check the commit authors and messages in evav, and confirm the company name.

Fremont prototype board F7F and the F7A/F7G codename sequence

• Description: Tyler maps the board codenames: F7A is the Steam Deck LCD, F7G is the Steam Deck OLED, and F7F is Fremont, described as an iteration past the Steam Deck OLED prototype board. A file pushed about four weeks before the video mentions Fremont outright in a QA-testing context.
• Confidence: Fact — the mappings and file reference come from the evav datamine.
• Category: Hardware
• Source: Datamined board codenames and file history in the evav mirror.
• Earlier mentions: None identified in this video.
• Verification: needs follow-up — confirm the F7A/F7G/F7F identifiers and the roughly four-week-old commit in the evav history.

Full-sized HDMI-A port on the Fremont device

• Description: The Fremont reference describes the device as wired directly to a full-sized HDMI-A port, not a USB-C port with HDMI output like the Steam Deck. Tyler says a full-sized HDMI port is something really only seen on dedicated, non-portable devices.
• Confidence: Fact — the port description is quoted from the datamined file; the “dedicated device” conclusion is Tyler’s inference.
• Category: Hardware
• Source: Datamined Fremont file in the evav mirror.
• Earlier mentions: None identified in this video.
• Verification: needs follow-up — read the underlying commit text and confirm the HDMI-A reference.

“Updating CEC endpoint for Fremont” commit

• Description: A pushed change explicitly names Fremont in the line “updating CEC endpoint for Fremont.” Tyler explains CEC as an HDMI feature that lets devices communicate with and control each other over the video cable, and says the work updates a microcontroller the transcript calls “Chrome OS C.” He notes the name is unrelated to the Chrome OS operating system and derives from Chromebook HDMI output support; the standard is open source.
• Confidence: Fact — the commit message and CEC explanation are presented as direct evidence; the “Chrome OS C” name is only as transcribed.
• Category: Hardware
• Source: Commit message in the evav mirror.
• Earlier mentions: None identified in this video.
• Verification: needs follow-up — locate the commit and identify the actual embedded-controller name and firmware target.

Fremont summarized as a powerful SteamOS console

• Description: Tyler summarizes that Valve is developing hardware on prototype board F7F, an iteration past the Steam Deck OLED board, with an AMD Lilac APU, HDMI communication protocols, and a full-sized HDMI-A port. Assuming Fremont is the Steam console, he describes it as a powerful purpose-built computer running SteamOS and the Steam Deck interface.
• Confidence: Mixed — the board, APU, and HDMI details are datamined facts; the “Steam console” identity is explicitly an assumption.
• Category: Hardware
• Source: Datamined evav commits plus Tyler’s synthesis.
• Earlier mentions: None identified in this video.
• Verification: needs follow-up — official Valve announcement or further datamined references to a console form factor and retail configuration.

Expected use of the leaked “big ass” Steam controller

• Description: Tyler expects the device would probably use the large controller leaked the previous month, shown with control sticks, touch pads, and all triggers including the back ones. He describes the combination as effectively a Steam Deck without the screen, while calling it a wait-and-see scenario.
• Confidence: Speculation — signaled by “probably” and “it’s really just a wait and see scenario.”
• Category: Hardware
• Source: Tyler’s inference from the prior controller leak and the Fremont datamine.
• Earlier mentions: References the controller leak from “last month” (“that big ass controller that we saw leaked last month”); no new details about the controller are added.
• Verification: needs follow-up — a Valve announcement or shipping documentation pairing Fremont with the leaked controller.

Steam Universe ambition from GDC 2015

• Description: Tyler says Valve very much wants to create the Steam ecosystem it first teased at GDC 2015 as Steam Universe, which it could not achieve then but could now, given the Steam Deck’s popularity and competitors copying it. He frames a Steam console as pushing the strategy further.
• Confidence: Mixed — the 2015 GDC Steam Universe tease is historical fact; the claim that Valve can now succeed is Tyler’s assessment.
• Category: Business/legal
• Source: Tyler’s analysis, referencing Valve’s 2015 GDC Steam Universe announcement.
• Earlier mentions: None identified in this video.
• Verification: needs follow-up — Valve’s 2015 GDC materials for the historical claim; no artifact supports the forward-looking assessment.

Assumed cross-compatibility between Steam devices

• Description: Tyler says any Steam device will likely have some compatibility with any other Steam device, but that exactly how Deckard or the Steam Deck would interface with this computer is unknown; he assumes the computer would ship with the leaked controller.
• Confidence: Speculation — explicitly hedged with “likely,” “unknown,” and “should be assumed.”
• Category: Technology
• Source: Tyler’s inference.
• Earlier mentions: None identified in this video.
• Verification: needs follow-up — Valve documentation or datamined references to cross-device pairing and streaming between Fremont, Deckard, and Steam Deck.

New or changed in this video

• New hardware codename Fremont and prototype board identifier F7F, positioned as an iteration past the Steam Deck OLED board (F7G).
• New APU codename Lilac, described as substantially more powerful than the Steam Deck’s APU; no specifications are given.
• New datamined evidence of a full-sized HDMI-A port and an HDMI CEC endpoint update for Fremont.
• New claim that QA testing was performed by a company called “Quant Computing” and that Valve imported the debug changes.
• The video introduces the “evav” Valve repository mirror as its datamining source.
• The Galileo segment is largely a recap of last year’s coverage (firmware, power-button patent, Valve employee photos); the reinterpretation of Galileo as a TV console rather than a VR streaming box is restated rather than newly evidenced.
• The Steam console identity, controller pairing, cross-device compatibility, and the Steam Universe revival are explicitly speculative.
• The video includes a paid sponsor segment for Castle Duels; it contains no HLX information.

Notable quotes

• “this Fremont device is wired directly to a full-sized HDMI a port not a USBC that has HDMI output like the steam deck” — the central hardware distinction Tyler draws from the datamine.
• “updating CEC endpoint for Fremont” — the commit message he cites as naming the device outright.
• “assuming that the Fremont is the steam console” — his explicit framing of the console interpretation as an assumption.
• “it’s effectively a steam deck without the screen” — description of the presumed console-plus-controller package.
• “it’s really just a wait and see scenario” — his confidence level on the product’s final form.
• “valve very much wants to be able to create the steam ecosystem that they first teased back in 2015 at GDC” — context for why Valve would pursue a console.

Open questions

• What architecture and specifications does the AMD Lilac APU have, and how does it compare with the Steam Deck OLED’s APU?
• Is Fremont the same device as Galileo, a successor, or a separate product line?
• What is the actual identity of the company transcribed as “Quant Computing,” and what was its QA role?
• Is the microcontroller transcribed as “Chrome OS C” a ChromeOS embedded controller, and what firmware is being updated?
• Will Fremont ship with the leaked controller, and what would it cost?
• How would Deckard, the Steam Deck, and Fremont interoperate, if at all?
• Does the full-sized HDMI-A port indicate a stationary console, a docked handheld, or a devkit rather than a retail device?
