Only two of the facilities had been featured in Pokémon games prior to the Battle Frontier's debut in Platinum. The Battle Tower and Battle Factory were both present in Emerald; the Battle Tower has been in every game since its debut in Crystal, excluding FireRed and LeafGreen, which featured a similar facility called Trainer Tower.
Upon the player's first entry into the Battle Frontier, their Vs. Recorder will be upgraded with a Frontier Record by a woman at the entrance. The Vs. Recorder keeps the amount of Battle Points the players has. It also contains the commemorative prints obtained from the Battle Frontier. One battle from within one of the facilities may be recorded and stored on the Frontier Record, which may be watched or overwritten with another at any time.
On winning through a set amount of battles in any given facility, Battle Points, or BP, will be awarded, usually in small amounts, but gradually growing through each consecutive streak. The Frontier Brain will only appear in single battle mode. Defeating the Frontier Brain of a given facility for the first time awards the silver commemorative print of that facility, and the second defeat of the same Brain gives the commemorative print a golden color. They are similar to Badges and equivalent to the Symbols from Hoenn's Battle Frontier. Three of the five Frontier Brains always use a certain team for silver print battles and another for gold print battles. At the beginning of each battle, they send out a random one of their three Pokémon. Also, defeating a Brain will always yield a 20BP reward. Battles conducted here do not award experience or money. Also, Pokémon seen in the battles will not be added to the Pokédex.
There are usually three forms of challenges. The first of these challenges is the standard single battle in which the challenger must engage in seven three on three battles in a row. Winning a set of seven battles earns the player Battle Points. The second of these challenges follows the same layout as the standard single battle but are rather conducted as Double Battles. Each facility also offers Multi Battles that two players can participate in, using the Nintendo DS's Wireless Connection, to increase their record. The Battle Frontier also allows players from around the world connect together using Nintendo Wi-Fi Connection to take part in multi Battles in any of the Battle Frontier facilities. This can be done by going to the Wi-Fi Club on the basement floor of any Pokémon Center, and selecting the Battle Frontier function. However, both players must have entered the Hall of Fame and visited the Battle Frontier at least once.
Regardless of what challenge is taken, the following Pokémon are not allowed:

The entrance hall is the entrance to the Battle Frontier from the Fight AreaPt or Frontier AccessHGSS. Because the Sinnoh Battle Frontier does not have a Pokémon Center, unlike Hoenn's, it cannot be accessed by Fly. Upon the first entry into the Battle Frontier, the Vs. Recorder will be upgraded with a Frontier Record by the women at the entrance. There are several women who will guide and explain venues of the Battle Frontier.

In the Battle Tower's lobby next to the PC is a man who considers himself a judge of Trainer's Pokémon. He can appraise one of the player's Pokémon by looking at its stats, specifically by checking how high the IVs are. First he describes the Pokémon's "potential", which is based on the sum of all six IVs. Then he indicates which stat has the highest IV and what range it falls in. If two or more IVs are tied for the highest then he will choose only one of them to comment on. In Sinnoh, he selects which highest stat he'll report randomly. In Johto, he cycles through the stats in the following order: HP, Attack, Defense, Speed, Special Attack, Special Defense. If a different Pokémon is shown, then the cycle will not reset.

Exchange Service Corner
The Exchange Service Corner is located at the center of the Battle Frontier. The player can buy various goods with Battle Points won from the facilities. The Battle Frontier's prizes are the same as Pokémon Diamond and Pearl's Battle Tower's prizes. They also use Battle Points which are won in the Frontier's various facilities. They can be bought at the stalls at the center of the Frontier.
While the menu structure differs, the items available in Pokémon Platinum are the same as the items available in Pokémon HeartGold and SoulSilver, except that TM89 (U-turn) is only available in Pokémon HeartGold and SoulSilver.
The Pokémon Scratch-Off Corner is located just north of the Exchange Service Corner. Pokémon Scratch-Off is a game that can be played for 1BP. This 1BP purchases three different Scratch-Off Cards, which permits winning up to 3 items. Upon purchase, a selection of 3 cards from four cards: red, blue, green, and yellow. Once done, scratching mode will begin. Using the stylus to scratch off the upper layer, scratching off three Pokémon gets the particular item that matches the Pokémon revealed. As soon as any part of any of the 9 blocks is touched, that block must be selected as one of the three choices. The whole card cannot be scratched off—only three blocks may be selected. If the player gets a Ditto, it acts as a wild-card, transforming into any other Pokémon should the player manage to get two of them. There are a total of three out of twenty-three different Berries to be won, and there will always be a Nugget to be won.
Platinum challenged the Battle Frontier while she and Looker conducted research on Giratina and the Distortion World, where Platinum's supposed-to-be bodyguards, Paka and Uji, had been sent to by Saturn in the previous chapter. By the end of the chapter, she had managed to defeat four of the five facilities, and was also intending to soon challenge the fifth one, the Battle Tower, led by Pearl's father, Palmer.
The Battle Factory is the only facility to not have a PC, due to the fact that players rent Pokémon instead of using their own.
The Battle Arcade is the only location in a Generation IV game to have moving animation while the player is saving, as the screens that show the player and their opponent's Pokémon flash, despite everything else pausing during the save.
In the Battle Castle, there are crosses above the foe's entrance which change depending on the round the player is on. For example, if the player is on round 1, then there is 1 cross.
In HeartGold and SoulSilver, the Pokégear will not play any radio channels whatsoever when the player is in any facilities. It is unknown why this happens.
In HeartGold and SoulSilver, the stat Trainers all appear in the Battle Tower without any reason, as the player character has never met them before in these games. This is possibly done to ensure full compatibility with Pokémon Platinum.
Trainers that received different overworld sprites in HeartGold and SoulSilver still use their Platinum sprites here.
