iDeck v0.1.3-alpha.3 — Build 67 · Repair, re-sign, play

iDeck v0.1.3-alpha.3 · Build 67

iDeck brings the Steam Big Picture experience to iOS. Genuine Windows Steam
runs locally through Madeira/Wine/FEX and Metal. This does not install Linux
SteamOS and is not PC streaming.

What's new since Build 56

• Repair Steam inside iDeck. The launcher now identifies missing/incompatible
  client/browser files and provides Repair Steam files. Existing account data,
  games and saves are preserved; replaced public program files are backed up.
  Reopen iDeck after repair. A compatible user-supplied client is required when
  no bundled repair source exists: iDeck/Steam32OfficialRepair in Files.
• 64-bit game installation detection. Wine now exposes the existing AMD64
  capability correctly to the legacy Steam client. The user confirmed Ratatan
  could download/install. This does not make every 64-bit game compatible.
• Ratatan startup/display work. Preserve emulator allocation headroom and
  Steamworks image space; restore fullscreen preferences with an original-value
  backup; enable the existing WGI controller route for isolated Steam sessions.
  Earlier device evidence reached the game menu. Universal fullscreen, virtual
  controller gameplay and Bluetooth success are not claimed.
• Re-signed JIT callback repair. Use URL schemes actually declared by the
  installed app instead of guessing from its Bundle ID. Keep the iDeck shell
  enabled for custom IDs. Correct the bundled shortcut's text output contract.
• Native Steam CM recovery. Clean up failed connections, preserve safe numeric
  transport errors and try up to three distinct existing CM endpoints for
  transient failures. Certificate checks stay enabled. This is not a verified
  fix for every LeiShen/Karing TLS issue, nor a Steam Cloud/offline-license bypass.

Upgrade / install

Download iDeck-0.1.3-alpha.3-build67.ipa, verify SHA256SUMS, and re-sign
with your own Apple development identity and matching main/helper profiles.
Keep the JIT helper and debugging permission. The IPA has certificate-free ad-hoc
signatures; it is not directly installable without your signature.

If you use Madeira JIT in Shortcuts, re-import it from this version's JIT setup
and replace the old shortcut with the same name. Updating iDeck does not replace
an already imported workflow. iOS26 users should use the manual LocalDevVPN flow.
Signing does not itself enable JIT.

Back up saves first. Upgrade in place with the same identifiers if preserving
local data; do not uninstall to fix a Steam prerequisite failure. Steam/CEF,
Microsoft redistributables, games, credentials, pairing data and personal signing
profiles are not bundled. Supply a legitimate compatible legacy Windows Steam
client and approve Valve login/Steam Guard yourself.

Signing guide

Actual checks and limits

• Full iOS Build67, ten focused host regression scripts and six release-tool
  tests passed. Signed shortcut payload/signature/source equality checked.
• 103-input portable relink executed; packaged main/JIT/converter section hashes
  match build products. Nested ad-hoc signatures and 1245-file scoped audit pass.
• Build67 was development-signed, installed in place and launched on Kusch;
  the user confirmed in-app Steam repair restored use. The phone's previous
  Steam executable was AMD64 while the compatible repair source was i386.
  The logout-crash causal chain is still unproven.
• The public ad-hoc IPA has no separate other-account sideloader/JIT acceptance
  test. No affected iOS27.2 accelerator TLS, iPad, exhaustive controller/game
  regression or full clean-machine runtime rebuild success is claimed.

This remains a developer alpha with limited game compatibility. Companion
assets supply exact application/pinned component sources, LGPL patches/build
recipes, 103 relink inputs, licenses, engineering audit and per-file inventory.
Toolchains/Apple SDK and signing permissions are obtained separately.

iDeck v0.1.3-alpha.2 — Build 56 · Six checks before takeoff

iDeck — six checks before takeoff

iDeck brings the SteamOS experience to iOS. This developer alpha runs genuine
Windows Steam Big Picture locally through Madeira/Wine/FEX and Metal. It does
not install Linux SteamOS or include Valve's client or games.

New in v0.1.3-alpha.2 · Build 56

• A step-by-step launcher: runtime → Steam/CEF → development signing → JIT setup → device connection → JIT for this session.
• One “Check all prerequisites” button: checkmarks, missing-condition actions and automatic rechecks after returning to iDeck/JIT setup. Manual launch waits for all six checks.
• More useful setup checks: a complete client may use either supported isolated prefix directory; incomplete clients cannot be combined to appear ready. Preparation preserves existing data.
• English and Chinese README: IPA signing/sideloading, Steam prerequisites and a staged testing guide.

Downloads and installation

Download iDeck-0.1.3-alpha.2-build56.ipa and verify it with SHA256SUMS.
The package has certificate-free ad-hoc signatures. Re-sign it with your own
Apple development identity/profiles, keeping the JIT helper extension and
debugging permission. Signing does not enable JIT.

Detailed signing guide

Companion assets include the exact application source snapshot, pinned
component/historical sources and vendored Rust dependencies, 103 Build 56
relink inputs, full component licenses, engineering audit and per-file IPA
inventory. Source/relink instructions are included in those archives.

What was actually checked

• Full iOS Build 56 compilation; launcher-policy, Steam launch/pseudo-process and keyboard host checks; six release-tool unit tests.
• Final linked prerequisite-check strings; portable 103-input relink executed successfully.
• Packaged main/JIT/converter Mach-O sections match build/input copies; all 20 native static libraries match the prior reviewed inputs.
• Nested ad-hoc signatures, 1,245-file scoped IPA audit and complete license/credit inclusion.
• Earlier Build 55 was installed and launched on Kusch; the checklist was visually observed at 6/6 ready. A later user foreground switch interrupted the attempted check-button tap, so that tap was not validated.

Build 56 has no fresh phone-installation, JIT or gameplay validation. The
Build 55 observation is not a claim of those results for this IPA. No
other-account Sideloadly/AltStore, iPad, Bluetooth or full clean-machine runtime
rebuild success is claimed.

Before testing

Requires iOS 26+, development signing and Madeira's authorized pairing/JIT
workflow. No jailbreak. Steam setup is still for technical testers: supply a
legitimate complete compatible legacy Windows Steam/CEF client yourself. The
clean client acquisition/setup flow remains unfinished. Sign in and approve
Steam Guard yourself; account caches are not supplied.

Game support is limited; startup, login transitions and games can hang or fail.
6/6 readiness is not proof a game will work. Back up saves before upgrades and
avoid deleting the app if you need to preserve its local data. Please report
device/OS/build, the first failing stage and redacted diagnostics.

致中文测试者

新版增加六步瀑布式检查与统一检查按钮。先自行签名侧载，再准备 Steam 客户端、配对与
JIT；通过检查后进入真正的 Steam。IPA 不含 Steam、游戏或账号。请分阶段测试启动、
登录、游戏库、游戏和返回流程。兼容游戏有限，本版本仍是技术测试用 Alpha。

Built on the substantial work of Madeira,
Wine, FEX, DXMT, StikJIT and idevice. DroidDeck
inspired the handheld direction. Credits
and component licenses are preserved. Apple's converter retains its separate
included agreement for shader conversion on Apple hardware. The review is an
engineering review, not a lawyer opinion. Independent project, no Valve/Apple
endorsement or authentication/Steam Guard/DRM bypass.

• source.tar.gz — application source, exact component revisions, historical sources matching the i386 runtime, and locked vendored Rust dependencies.
• relink.tar.gz — 103 main-library link inputs and a tested portable relink recipe for modifying static libraries.
• licenses-audit.tar.gz — component licenses, attribution, provenance and engineering review.
• SHA256SUMS and the IPA inventory — download integrity and scoped package checks.

Installation and prerequisites ·
Source/relink guide

What was verified for this package

• Full iOS Build 54 compilation with StikJIT rebuilt from pinned Swift/Rust source.
• A second StikJIT build using exported source and vendored dependencies with networking disabled.
• Dependency notices for 162 StikJIT input packages and 108 pairing input packages; missing upstream texts/declarations supplemented with provenance.
• All 17 required prior StikJIT Swift imports are provided. Packaged main/JIT/converter code sections match their respective build/input sections.
• Static-library replacement/relink proof, portable Build 54 relink, nested ad-hoc signature verification, archive integrity and scoped excluded-payload checks.
• Full component license texts and credits are included in the IPA as well as companion materials.

Before you jump in

• iOS 26+, developer signing and Madeira's authorized JIT/pairing workflow are required. No jailbreak is needed.
• Steam setup remains for technical testers. Supply a legitimate compatible full Windows Steam/CEF client tree. The tested legacy-client acquisition/setup flow is unfinished. Sign in and approve Steam Guard yourself; no account or login cache is supplied.
• Compatibility is limited. Startup/login transitions and games can hang or fail. See Madeira compatibility information.
• Prior physical evidence is from an iPhone 15 Pro Max. This package's phone installation was skipped at the owner's request. No new on-device JIT/gameplay, iPad, or different-account AltStore/Sideloadly validation is claimed. There is no full clean-machine rebuild claim for the entire Wine/FEX/DXMT runtime.

Component licenses and the adopted Madeira Converter Exception are preserved.
The Apple converter remains under its own included agreement for shader conversion
on Apple hardware. This is an engineering distribution review, not a lawyer opinion.
Independent project; no Valve endorsement, authentication/Steam Guard/DRM bypass,
Microsoft redistributables, developer profiles, private signing keys or game payloads.

Built on the substantial work of Madeira,
Wine, FEX, DXMT, StikJIT and idevice, with thanks to their authors and contributors.
