If the device can be used prior to the end of the game it is feasible that it could save time but further testing is necessary,įrom what I have read on the subject the standard "E-Reader" device will not work with the MMBN5 e-reader cards and as such the E-Reader+ is required. I myself have not had the opportunity to experiment with this peripheral and the e-reader functions in general owing to the fact that I do not own one. This is the Japanese exclusive E-Reader+, it never made it's way to North America. The Navi Data Chips were for the most part readily available with a few exceptions, namely the Toadman, Meddy and Numberman Navi Data Chips which were only available from special booster packs given away at conventions in Japan. The main issue with that is the fact you must take your hands off of the controller momentarily and also the availbility of these "Navi Data Chips".
To tag a navi (say Protoman) you must insert the Protoman Navi Data Chip into the gate. The main drawback to the peripheral is in how you "tag" a navi. From what I have currently tested it is most useful in the span of time between Blizzardman and Magnetman/Knightman but may still prove useful elsewhere. (Exeptions include any segment in which you do not control Megaman). In the main story the BCG allows you to temporarily "tag" a navi you have already befriended in the main story and use them for a single turn in most battles. Proof of this is shown by the fully translated "OPS Battle" menu area that is unlocked once the peripheral is connected to your game.
The Battle Chip Gate is an amazing peripheral that was intended for release in NA at one point before eventually being cancelled. Here are some notes from doicm that may be helpful in the speedrun (in powerpoint form): Peripherals Battle Chip Gate
The game is also generally considered the most difficult in the series (to speedrun). MMBN5 was Capcom's attempt to make up for the lack of content in the previous installment, because of this the game contains a slightly stronger plot and is much longer.
