What is Mario Kart Double Dash RTGP?

Mario Kart Double Dash RTGP (Retro Track Grand Prix) is a free fan-made mod for the GameCube classic Mario Kart: Double Dash!!. Created by developer Lilith after a year of solo work, it adds 48+ retro tracks from earlier Mario Kart games, remastered to fit Double Dash's mechanics. Enjoy snaking through SNES courses, battling on GBA tracks, or drifting N64 favorites—all with custom models, animations, and an original soundtrack (or optional classics). Plus, extras like a randomized Extender Cup and LAN/netplay support make it endless fun.

This mod runs perfectly on Android via Dolphin Emulator, even on mid-range phones. No need for a PC or real GameCube hardware!

Requirements for Playing RTGP on Android

Before we start, ensure you have:

• A clean NTSC USA Mario Kart: Double Dash!! ISO (1.4GB size, Game ID: GM4E01). Avoid compressed or modified versions—your 400MB file won't work!

• The RTGP mod ZIP from GameBanana: Download here.

• An Android device with at least Snapdragon 855 or equivalent for smooth performance.

• Dolphin Emulator from the Google Play Store (official or MMJR fork for better Android support).

Note: Always use legal backups of your own games. This guide assumes good faith.

Step 1: Patching the ISO with RTGP Mod

The first step is patching your clean 1.4GB USA ISO with the RTGP .xdelta file. We'll use the free online tool Rom Patcher JS for easy Android-friendly patching—no extra apps needed!

1. Open Google and search for "Rom Patcher JS". Click the first result to load the website.
2. Extract your RTGP ZIP to get the .xdelta file.
3. On Rom Patcher JS, click "ROM File" and select your 1.4GB Mario Kart Double Dash ISO. If it says "file is too big," hit "Force Calculate Checksum" and wait.
4. Click "Patch File" and select the .xdelta from RTGP.
5. Hit "Apply Patch" and wait—your new 1.82GB patched ISO will download automatically. It won't use much data!
6. Move the patched ISO to a folder accessible by Dolphin.

Pro Tip: If patching fails, verify your ISO size and region. The modded ISO should have Game ID GM4E08.

Step 2: Installing and Setting Up Dolphin Emulator on Android

Download Dolphin Emulator from the Play Store and open it. Here's how to optimize for RTGP:

1. On the home screen, click "Add Games" and select your folder with the patched ISO. Refresh—the game should appear!
2. Go to Settings > Config > General: Enable cheats (if using any) and save states.
3. Interface tab: Enable "Cutout to the Area" for better screen fit.
4. Graphics Settings: Set Video Backend to Vulkan (for Adreno GPUs) or OpenGL (others). Aspect Ratio: 16:9 or Stretch to Window.
5. Enhancements Tab: Internal Resolution to 3x (based on your device—don't exceed for lag). Enable Widescreen Hack.
6. For extra boost: GPU Driver > Select Turnip driver (Snapdragon/Mali compatible).
7. Go back and launch the game from the banner.

These settings ensure 60FPS on most devices, with HD visuals and no glitches. Test on a track like N64 Rainbow Road for that retro Double Dash vibe!

Step 3: Launching and Playing the Game

Once set up:

• Start the game and create a save.
• Select players, game mode (Grand Prix, VS, etc.), vehicle CC (50cc-150cc).
• Pick your character duo (e.g., Mario/Luigi for balanced stats).
• Choose a Cup—now including retro ones—and race!

Troubleshooting Common Issues

• Game Not Showing in Dolphin: Ensure ISO is 1.82GB patched version. Refresh list.
• Lag or Crashes: Lower internal resolution to 2x or switch to OpenGL.
• Patching Errors: Use a full 1.4GB clean ISO—avoid WBFS or RVZ formats.
• No Sound/Glitches: Update Dolphin or check audio backend in settings.
