Triple Battles Only - Black/White/Black2/White2

Turns all battles within the generation 5 Pokemon games into all triple battles.

Download on Github

This project came as a request from Don Shnack as a potential stream/video idea he could do for his channel. I had no background in modding Pokemon games, but thought it was possible since the Pokemon Universal Randomizer had the option to make all battles double battles. Turns out, there was some talk about the idea online, but nobody had a tool to do it. For his stream I modified all the trainers by hand, but saw that others were interested in doing their own runs of the mod. That brings us to this tool that automates the process of setting the flag for each trainer. Granted, this could be improved a lot in terms of having a user interface and not having to extract files from the game itself, but again, modding these games I'm unfamiliar with. Maybe someday I'll revisit this and improve it, or if you want to take a shot at it, all the code is on the github page linked above.

Installation Instructions

You can either watch the video below, or follow the written instructions below.

Disclaimer

This program modifies files within a folder at the binary level. Incorrect usage of this tool can lead to potential data corruption. There are a number of checks in place to mitigate the chances of this occurring, but use this tool at your own risk.

Required Tools

• Universal Pokemon Randomizer - Used to randomize the game and set some of the flags that this tool doesn't set. This tood requires Java to run
• Nitro Explorer 2 - Used to extract the compressed files from the game.
• NDS Editor (kiwi.ds) - Used to decompress the extracted files from the game.

Optional Tools

• Kazo's B/W Tools - Not required to make the triple battles, but the included trainer editor can be useful to ensure the tool worked.

Usage

1. Open the Universal Pokemon Randomizer and load your game into the tool. Most of the settings within here are fair game. Though there are two required settings to set.
   • Under Foe Pokemon, randomize the trainer's pokemon and check Double Battle Mode. This ensures that the trainer's AI is set to the multi-battle AI, so they won't attack their own pokemon.
   • Also under Foe Pokemon, check Boss Trainers, Important Trainers, and Regular Trainers under Additional Pokemon for.... Set the amount of pokemon to add to each group to a minimum of 2. This will ensure that all trainers have at least 3 pokemon, which is required for the triple battles to activate.
   • While not required, it's also recommended to set the trainer and wild pokemon Percentage Level Modifier to around +20%, since you'll be getting a lot more experience with all the added pokemon, it should even out the level curve.
2. Once all your randomizer settings are set, hit Randomize (Save) to create your randomized game.
3. Now open Nitro Explorer 2 and load your randomized game. Within here, you're going to extract the following file depending on which game you're modifying:
   • Black 1/White 1: Extract a/0/9/2, name the file trdata.narc.
   • Black 2/White 2: Extract a/0/9/1, name the file trdata.narc.
4. Now open NDS Editor (kiwi.ds) and drag your trdata.narc file into the window. Double click on the added entry to the list, check all files within the archive, and extract all files. This should create a folder named trdata within the same folder as NDS Editor with the specified number of files within it:
   • Black 1/White 1: 616 Files
   • Black 2/White 2: 814 Files
5. Now in the Triple Battle Converter folder, double-click on TripleBattleConverter2.exe and a small window should pop-up.
6. Within the window, click on the Browse... button and navigate to the newly created trdata folder. Select it and click Select Folder.
7. Select which game you're converting below, and then click the Convert button. If all went well, you should see a window pop-up with Modified 616/814 Trainers inside. That means all the trainers are now triple battles!
8. Now reopen NDS Editor (kiwi.ds), and in the toolbar, go Tools > Make Narc File... In the upper field, select the path to the trdata folder that we just modified and click OK. You should now have a new trdata.narc file within the same folder as the NDS Editor (kiwi.ds).
9. Now reopen Nitro Explorer 2, load your randomized game, and navigate to the same file that you extracted. Instead of extracting, you're now going to select Reinsert. Navigate to the trdata.narc file you've created and select it. The status bar at the bottom should now say Reinserted 1/2 successfully. Your game is now ready to play!

Limitations

There are a handful of trainers in each game that aren't triple battles. This seemed by design from the Universal Randomizer, so I followed their example. They are the following:

• Black 1/White 1: First battle against Cheren, Bianca, and N.
• Black 2/White 2: First battle against Rival and Multi-Battle with old player character.
