KartPad

Previous builds have been retired; a new version is in progress.

Android targets ARM64/Vulkan on Android 9+. Device-specific graphics corruption, freezes and slowdowns remain unresolved; a successful Pixel run does not certify other phones. Apple TV is an experimental tvOS 17+ preview with separate controller and hardware acceptance. See Android setup and Apple TV setup.

The tested iPad migration build reached Retro WFC with a new license. An existing license's serial mismatch reproduced on both old and new builds. Earlier Android tests reached Retro WFC and the worldwide lobby, but this release does not claim a newly verified complete online race/reconnect sequence or compatibility on every device. Native room hosting and Original Wiimmfi compatibility remain unfinished. See online status and friend-room guidance.

Yes, with the separately installed 6.12.8 content and matching compiled profile. A newer Retro pack can require a new KartPad build; replacing files alone does not update translated game code. Apple checks the version before launch; Android checks the official version during installation and validates installed content at launch. Follow your platform setup guide if a compatibility update is requested.

Choose the game when KartPad opens. On iPhone/iPad, ••• → Return to KartPad Menu pauses the session; Resume continues it. Choose Use on Next Launch for the other game, fully close the app, then reopen it. Returning to the chooser alone does not apply pending license edits. Mac game selection also applies after reopening. See the platform installation guides for their distinct flows.

On iPhone/iPad, hold A for one uninterrupted second to lock acceleration; tap A again to release it. Touch settings let you move, resize, hide and restore controls, including the normally hidden D-pad for tricks. Motion steering is optional and offers recenter, inversion and sensitivity. See the mobile controls guide for floating-stick behavior and controller handoff. Android has its own controls/settings guide.

Yes. Pair controllers in the operating system, choose Multiplayer in the game and press each pad’s mapped A button to register. On iPhone/iPad, the first controller shares Player 1 with touch; the other players keep stable slots. Full three/four-player and reconnect acceptance remains incomplete. See controller setup and adapter limits.

On iPhone/iPad, ••• → Game Data & Saves → Player Identity… manages names and exact license slots. Restart to apply edits. Standard 74-byte .mii appearance import is experimental, not a full Wii Mii editor. Renaming a Mii and renaming one license are different actions. See identity instructions. Android save/rating transfer does not include the Mii database.

Experimentally, on macOS only, using the direct Bluetooth pairing flow. It still needs broader original-hardware, reconnect and long-session testing; it is not an iPhone/iPad feature. See pairing instructions and hardware limits.

Package size varies by platform and version; the iPhone/iPad app is about 65 MB. Extracted base-game data is roughly 2.5 GiB, and Retro content, the original image and temporary installation files require more. Android setup recommends at least 6 GiB free. Check the platform guide and leave room for updates; the app size is not the installed-data footprint.

No disc image or extracted retail assets are included. Supply your own legally obtained supported PAL RMCP01 revision 0 image. Public packages contain compiled translated logic, so software licensing and game-content rights are separate; see rights and provenance. Do not request or attach game data in issues.

No. It is a game-specific static recompilation for supported Mario Kart Wii and Retro Rewind profiles, not a loader for arbitrary Wii games.

The game runs locally as native ARM64 code translated by WiiCompiled, with Vulkan on Android and Metal on Apple platforms. It is not streamed from another computer or run inside the Dolphin emulator. KartPad does use Dolphin-derived components, including game-data handling; third-party notices preserve that attribution.

No. PowerPC code is translated ahead of time and compiled into the app. The iPhone/iPad app does not JIT-compile PowerPC or execute a newly downloaded PowerPC patch. New executable profiles require a compatible app build.

First-use shader/pipeline compilation can cause stalls, and heat or higher render resolution can worsen performance. Not every freeze is shader compilation. Android has separate unresolved character corruption, online-menu stalls and cup-transition crashes. Start at 1x Native, but do not treat a settings change or passing renderer probe as a confirmed fix. Use known issues and diagnostic guidance to match your symptoms; the preview adds useful changes and logs, not a blanket stability guarantee.

Those settings applied to Sunshine-specific CPU-clock and 60 FPS behavior and did not affect KartPad’s Mario Kart Wii runtime. They were removed because they were misleading no-ops. Use actual display controls and the performance guidance.

Supported in-place updates preserve saves; do not uninstall or clear app data. Keep backups and the same signing identity/bundle ID. Android private previews have a different signer and need a planned migration. Raw save backups do not include every companion file: Android preview 1 adds matched offline Retro rating restore, and the reporter confirmed that workflow succeeded. Mii transfer and online/server synchronization remain separate unfinished work. See save and rating transfer.

No. Check current platform acceptance, known issues and technical debt. Report your exact build, device/OS, selected game, settings and reproducible steps using the reporting guide to choose KartPad or WiiCompiled. Export a problem report using the support guide, review it before sharing, and keep saves, identities and game data private.
