KartPad

KartPad 0.5.3 — Android, iPhone/iPad and Mac:

Android 0.5.3 / code 231, iPhone/iPad 0.5.3 / build 87 and Mac 0.5.3 / build 86.

All three were compiled from 838214b23d959b7c7b7a298e4d9fb567b17ce92f. The Android APK is signed with the same key as 0.5.0–0.5.2 (certificate SHA-256 c1dbe0a0d72d830a5779476b346a750d0a37515adef992cad2f3863058f7f2f2). License notices are inside the IPA and Mac ZIP; the Android notices are unchanged from KartPad-v0.5.1-notices.zip.

iPhone, iPad and Mac:

• Cup select no longer drops to 20–30 FPS (#327). The course-preview videos on the cup screen were decoded through a slow memory path on Apple devices. Measured on a Mac with the same steps before and after: Select Cup went from 29–30 FPS to a steady 60 FPS.
• Single Joy-Con (iPhone/iPad, #324): KartPad now listens for a lone Joy-Con through both of iOS's input channels, and the diagnostic report records which buttons iOS says it has, so if it still doesn't respond we can see why.

Android:

• New experimental option for Snapdragon track textures (#102). Help → Character Graphics Test… → Experimental: fix characters and track textures (Snapdragon, may be slower). It applies the character fix to every draw, which may also fix the striped track and wall textures on phones like the Z Fold 8. It costs extra CPU, so keep the character-only option if it's slower for you. Fully close and reopen KartPad after choosing it.
• The same memory-path fix is included. Most Android phones already used the fast path, so expect little change there.

Updating:

• Android: install the APK over your current version. Do not uninstall or clear app data. Same signing key as 0.5.0–0.5.2.
• iPhone/iPad: sign the unsigned IPA with the same identity and bundle identifier as your current install and install it over the existing app.
• Mac: replace the app. Your data is kept in Application Support.

Game images and the Retro Rewind asset pack are not included.

Known limitations:

• The Snapdragon options are experimental and unconfirmed on affected phones. On the S24 Ultra (Adreno 750) the character fix does not help yet (#104, #193, #211).
• Single Joy-Con on iPhone is untested with real hardware.
• Low-end phones are still well below 60 FPS; PowerVR GPUs still can't start (#304); the trophy-ceremony crash (#131, #323) is still open.

KartPad:

KartPad builds on WiiCompiled, the original Mario Kart Wii static recompilation project created by patchzyy. WiiCompiled provides the foundational translator and runtime; KartPad maintains the Apple and Android integration, native controls, game chooser, game-data management, packaging, and releases. The projects are independently maintained.

Bring your own game data. KartPad requires a legally obtained supported PAL RMCP01 revision 0 Mario Kart Wii image. Downloads contain translated game logic, but no disc image, extracted game assets, Retro Rewind pack or saves. Apple IPAs require local re-signing; tvOS remains experimental.

Update before online play. The downloads below include the console-serial.

Older affected builds should stay offline. Updating preserves identities and saves; existing server-side identity history or bans require service-admin review.
