This is the gold standard for randomizing Generation 1 through Generation 5 games. It is an open-source Java application.

Because the Randomizer is built on Java, you must have the installed on your computer. If you do not have Java, the program will not launch.

| 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 | | Randomizer won’t open (.jar) | Java not installed or outdated | Install latest Java Runtime Environment (JRE) from java.com.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.” |
