BCD runs Windows PC games on iOS and iPadOS. Wine provides Windows, FEX runs x86 and x64 code on Apple's chips, and DXMT plus BCD's Direct3D 12 runtime draw with Metal. BCD signs in to Steam, downloads the games you own, and starts them directly or through Valve's own Steam client (BCD Dock).

BCD is a fork of Madeira by Will Faust and its contributors (see Credits).

A free Apple ID keeps only three sideloaded apps active at once. BCD, StikDebug (where you need it for JIT) and SideStore or AltStore can fill all three. The usual way around it is LiveContainer, which runs more apps inside one container. A typical setup: GetMoreRam gives LiveContainer the Increased Memory Limit entitlement (you can remove GetMoreRam afterwards), StikDebug provides JIT, and BCD runs inside LiveContainer. If something breaks inside LiveContainer, try BCD outside it before you report a problem.

• A whole new app around the games:
  • your library with store cover art, search, sorting and a menu on every card;
  • a page for each game with all its settings in one place;
  • the controller works everywhere: every screen, the in-game menu, the touch-controls editor;
  • a lightweight in-game menu, performance overlay and on-screen touch controls.
• Steam: sign in (password with Steam Guard, or a QR code), your owned library, downloads and updates, file checks, Steam Cloud saves. Downloads keep going in the background on iOS 26.
• GOG (new, early): sign in, download and play your GOG games, with no launcher running inside Windows. The Epic Games Store is next.
• BCD Dock: Valve's Steam client starts the games that need Steam, without its window. Those games run through Valve's own client, signed in with your account.
• Graphics: Direct3D 9, 10 and 11 through DXMT; Direct3D 12 through BCD's runtime and Apple's Metal Shader Converter.
• 32-bit and 64-bit games, controllers (DualSense with rumble, adaptive triggers and light bar; Xbox; Switch Pro; MFi), keyboard and mouse, and a controller-to-keyboard-and-mouse mode.
• Recommended settings that stay current: every known game ships with tuned settings, and one tap on a game's page fetches the newest list. Per-game settings also tune themselves after a crash.
• .NET games through Wine Mono, downloaded in the app.
• Feedback from the app: Settings › Feedback to tell us what is broken or what to improve, and Send Log after a crash.

Tuned settings are built in for these games. They are the licensed Steam versions, started through BCD Dock:

• God of War
• Ghost of Tsushima
• Horizon Zero Dawn and Horizon Forbidden West
• Red Dead Redemption 2, including the Rockstar Launcher
• GTA V, Legacy and Enhanced
• Crysis Remastered, Crysis 2 Remastered and Crysis 3 Remastered

Also running: Warcraft II: Battle.net Edition. Work in progress: Ratchet & Clank: Rift Apart (around 20 FPS, with visual glitches).

How well a game runs varies a lot; many games do not start yet.

• iPhone or iPad on iOS / iPadOS 18 or later, with an A13 chip or newer. Games that use geometry shaders or tessellation need an A14 or newer; the heaviest games need an A17 Pro or M-series chip and plenty of memory. Devices with an A12 or older chip are not supported (their GPUs lack what Direct3D needs).
• JIT. iOS lets only an app a debugger starts generate code, and BCD needs that for every game:
  • iOS 26 or later on A15 / M2 and newer: BCD's built-in helper (paired once on the device), or StikDebug;
  • iOS 18, and iOS 26 on older chips: StikDebug, with its "Always Run Scripts" setting on.
• A way to install the IPA: SideStore or AltStore (a free Apple ID works), LiveContainer, or your own signing. More memory for big games: GetMoreRam adds Increased Memory Limit and extended virtual addressing to BCD's App ID.
• Room: each game needs its full install size on the device.

1. Download BCD.ipa from the latest release.
2. Install it with SideStore, AltStore or LiveContainer.
3. Open BCD. Setup walks you through JIT, LocalDevVPN, Steam and the extra runtimes.

1. When a game crashes, freezes or is closed by iOS, BCD's auto-tune suggests a fix. It is on by default (Settings › Logs, and a switch on each game's page). Tap Close BCD, open BCD again and start the game again. Let it go on, round after round, until it is done.
2. When auto-tune gives up, its message offers Send Log. Send that log: it has what is needed to look into the game.
3. For ideas and everything else, use Settings › Feedback.

BCD's packages carry no Microsoft software. The Visual C++ runtime most games need is downloaded from Microsoft inside the app, after you accept Microsoft's license terms, and kept unchanged on your device. Wine Mono comes from WineHQ the same way.

The build is the workflow .github/workflows/build-ipa.yml and the scripts it runs under build/ and tools/, step by step. Every release also carries BCD-source.tar.xz, the complete source of that release: this repository and all its submodules at the release's pins.

BCD is free software under the GNU General Public License, version 3 (LICENSE), with the Madeira Converter Exception (LICENSE-EXCEPTION.md). Madeira's own code is under version 3 or (at your option) any later version; BCD's own files (marked "BCD Material" in their headers) are under version 3 only, so BCD as a whole can be used under version 3. They also carry additional terms under GPL-3.0 section 7 (LICENSE-BCD.md): an app that includes them shows "Includes work from BCD by thebcd69 (https://github.com/thebcd69/bcd-games)" on its About, Credits or Licences screen, keeps their copyright lines, and marks changed files as modified.

Madeira, which BCD is a fork of:

• Will Faust (willfaust): created Madeira
• Nick (125hz): 32-bit game support, the game library and Madeira Dock (BCD Dock here)
• Jfishin (Jfishin): the original native Steam sign-in, library and downloads
• Jesse (JesseLovelace): Steam Cloud saves, faster game launches, and fixes that let more games run
• Dan Perks (danperks): in-app JIT without StikDebug, and pairing without a computer
• spitefulowl (spitefulowl): Wine and FEX runtime fixes, DXMT texture and memory fixes, audio, the swap tier, and library launch options
• meshoklv (meshoklv): controller fixes, touch taps that stay off the mouse, and a crash-guard fix
• TheHadesc (TheHadesc): Madeira Dock starts for more games, and a touch gamepad that survives the in-game keyboard

The projects underneath: Wine, FEX-Emu, DXMT by Feifan He (3Shain) with the Direct3D 9 frontend by David Acevedo (dacevedo12), rpmalloc by Mattias Jansson, StikDebug, StikJIT, idevice, FreeType, and every library listed in THIRD-PARTY-NOTICES.md. Thank you to everyone who works on them.
