This tool calculates the trainers and pokemons that you will encounter in the Battle Subway in Pokemon Black 2 or White 2 based on your profile, the time you boot the DS and the number of current wins. The tool uses the average of Timer0Min and Timer0Max to determine the initial seed. On emulator, the Timer0Min and Timer0Max should be the same. The tool assumes no buttons is held when booting the game.
After changing the DS clock, loading the game and changing map will cause daily events to reset which will increase the PID RNG frame, causing the pokemons to be different than what the tool says. To avoid this issue, change the DS clock, load the game, leave the subway entirely, save, come back inside and save again next to the operator.
This will display the list of expected trainers based on the inputs:
--profile: Path to profile json file. Use other tool such as PokeFinder to find the right values. Default: ./profile.json--dateTime: Date when the game is started, in yyyy-m-d-h-m-s format. Default: 2009-1-1-0-0-0--wins: number of wins so far in the Battle Subway. Must be a multiple of 7. For Battle Institute, must be 0. Default: 28 wins--subwayType: The type of subway. Possible values: normalSingle, superSingle, normalDouble, superDouble, battleInstituteSingle, battleInstituteDouble. Default: superSingle--pidRng: Advanced. The PIDRNG value (in hex format) before talking to the subway operator. This overwrites the PIDRNG value determined by --profile and --dateTime. Ex: 0xF234567812345678. No default.--printRngFramesInfo: Advanced. Display RNG frame info for RNG searchers. Default: false
Input example:
PokemonB2W2BattleSubwayRNG.exe --profile ./profile.json --dateTime 2021-4-18-23-54-9 --wins 0
PokemonB2W2BattleSubwayRNG.exe --profile ./profile.json --dateTime 2021-12-31-1-2-3 --wins 7 --subwayType superDouble
PokemonB2W2BattleSubwayRNG.exe --pidRng 0xF234567812345678 --wins 14 --subwayType superDouble
Output example:
Date: 2009-01-01-00-00-00
Seed: 0x802accf7048bb49f, InitialAdvances:57, PIDRNG: 0x9cb929d058fb6096

The tool can also be used to find the boot time that will give you the most chance to win. For example, it can determine that if using Volcarona, the best time to boot the game is at 2066-9-10-5-27-57, because if booted at that time, 19 out of the 21 pokemons in the series is outsped by Volcarona and Volcarona is guaranteed to OHKO them.
--playerPokemonsFile: Path to the file containing pokemon ratings. Check ./b2w2_playerPokemons.json for an example. "ratings" is an array of [PokemonBattleSubwayId,AbilityIdx,Rating] To determine the PokemonBattleSubwayId of a pokemon, check ./b2w2_pokemons.json For example, [408,0,1] means that encountering a Skarmory (id=408) with ability Keen Eye (AbilityIdx=0) has a +1 rating. Default: ./b2w2_playerPokemons.json--playerPokemonsIdxFilter: List of indexes of player pokemons to consider from the file --playerPokemonsFile, separated by commas. For example, the file of --playerPokemonsFile contains 20 pokemons, but you only want the tool to consider the pokemons at index 7 and 11. In that case, you'd use --playerPokemonsIdxFilter 7,11. If omitted, all pokemons of the file are considered. No default.--filterMinRating: The minimum rating score that the trainer series must have in order to be printed. Recommended value for superSingle: 19. Recommended value for superDouble: 25.
In normalMulti and superMulti, your own pokemon influences your teammate and thus, the trainers you will face. This means you must provide information about your own pokemons.
--multiTrainer: The battle orientation of your teammate. Either attack, defense or balanced. Default: attack.--playerPokemonsFile: See above. This option is considered even in "generate" mode.--playerPokemonsIdxFilter: See above. --playerPokemonsIdxFilter must contain 2 elements that represent your 2 pokemons.--multiTeammateUnknownFrameAdvance: Number of frame advances after selecting your teammate in multi battle. The logic that determines the number of advance is unknown. There is about 25% chance to be 12 advances. Thus, the tool calculates the correct list of trainers only 25% of the time. Further reearch is needed to automatically determine that value. Default: 12
