Generation 5 games feature strict anti-piracy measures. Ensure your emulator is updated to its absolute latest version, as modern versions of MelonDS and DeSmuME bypass these checks automatically without requiring manual action-replay codes. If you want to customize your setup further, let me know:

: Open the extracted folder and double-click the appropriate launcher for your operating system:

: Ensure you have 64-bit Java installed on your computer, as the randomizer requires it to run.

The software will analyze the file and display the game title in the top left pane once successfully loaded. 4. Customizing Your Randomizer Settings

Randomize the teams of Gym Leaders, Rivals, and Grunts. Checking "Type-Themed Gyms" keeps the structural integrity of Gyms while giving them entirely new rosters.

A Nintendo DS emulator is required to play the ROM. Popular choices include DeSmuME and MelonDS.

Some ROMs have "AP" (Anti-Piracy) checks that stop you from earning EXP. If this happens, you may need an "AP-Patched" version of the ROM.

Pokémon can learn completely uncharacteristic moves as they level up.

Give Pokémon completely chaotic new abilities (like a Wonder Guard Spiritomb) and random level-up moves. Prerequisites: What You Need Before Starting

| Problem | Likely Cause | Solution | |---------|--------------|----------| | White screen after loading ROM | Bad ROM dump or corrupted randomization | Redump ROM or reduce number of randomization features. Try randomizing only wild/trainers first. | | Randomizer won’t open (.jar) | Java not installed or outdated | Install latest Java Runtime Environment (JRE) from java.com. | | Game crashes at a specific route | Overly aggressive randomization (e.g., illegal move sets) | Re-randomize with “prevent illegal moves” checked. | | Flashcart says “NDS not found” | ROM name has special characters | Rename to simple b2random.nds . | | Rival has level 3 Legendary (too hard) | “Similar strength” not checked | Re-randomize with “Consider trainer strength” enabled. | | Can’t evolve Gengar/Machamp | Trade evolution not fixed | Re-randomize and check “Remove trade evolutions.” |
