Mega Man Battle Network 4.5: Real Operation – English Translation

UPDATE: Version 1.1 is now available! Download it from the same link below, and check the README for more info on how to update.

In late 2003, Capcom released Mega Man Battle Network 4 for the Game Boy Advance. Even though most fans in the West don’t think of it very highly, the game became a runaway success, selling over 1.3 million units worldwide in its lifetime. In response, Capcom scrambled to make a follow-up that would utilize one of MMBN4’s unique peripherals: the BattleChip Gate. In just half a year, they developed Rockman EXE4.5: Real Operation, a game that fully embraced the use of the BattleChip Gate and real-life BattleChips that were already on the market.

Perhaps due to the BattleChip Gate never being released overseas, or perhaps because Mega Man Battle Network 5 was already on the way… Rockman EXE4.5 was never localized for Western audiences. Until today! After several years of development, Mega Man Battle Network fan-community The Rockman EXE Zone is proud to present a complete English localization of this game, now titled Mega Man Battle Network 4.5: Real Operation! Now, 15 years after its original release, English-speaking fans will finally have the opportunity to experience Mega Man Battle Network 4.5 in all its glory!

Rockman EXE4.5 is an outlier in the series, lacking the traditional story and battle system that players had come to expect. The game places you in the role of the operator; instead of controlling just MegaMan, you can choose from over 20 different NetNavis to play. In battle, you don’t control your Navi directly, but they move on their own, and you are restricted to sending them commands and BattleChips. The game featured a Real-Time Clock, and its slimmed-down single player campaign revolved around an Internet that changes in real-time, even while the game is shut off.

The game has been painstakingly localized into English, with all the same quirks and whimsies that were present in the English localizations of the other games in the series. Indeed, our goal with this project was to localize the game in such a way that it would be indistinguishable from an official Capcom localization, had one been released sometime in early 2005! With that said, we’ve also implemented a variety of fixes and improvements that one might have found in a Capcom localization, had they given it more time in the oven and a higher budget than usual.

And that’s not all! We’ve also thrown in a couple of extra goodies, some of which can be downloaded here exclusively at TREZ.

  • A North American and European patch, each with their own title screen and minor differences.
  • A fully localized Instruction Booklet in the same style as the other games!
  • A North American boxart for the game.
  • An Upgrade Patch for the Japanese version of the game, which backports all our bugfixes.
  • A translated interview with the development team from the Rockman EXE4.5 official strategy guide.
  • Starter save files for those who just want to play with their favorite NetNavi.

    1. Your Map for net 9 has a typo: it says you get wide sword from BMD B when it should be wide blade. (Using your map to find Protoman’s power ups, he only gets, like, 2. (T-T))

  1. This is amazing , thank you guys so much it’s been such a hassle to play it with the partial eng patch but now we can enjoy the game to the fullest, really appreciate all of people involved in making it happen

  2. I recall that during the development compatibility with the Real Battle patch was expected for the final release. Is that in this version?

    1. They can’t release it on physical form without CAPCOM saying “ok” and having 99% money from it.
      The patch is as far as they can go without starting unnecessary wars.

It says in the readme that 4.5 has issues on VBA, try using no$gba. the only error I’ve run across is a small graphics error after you beat a tournament (which is also mentioned in the readme).
