Rockman 20XX: Tatakae! Team Shachi!, the officially-licensed browser game by Capcom and Team Shachi, ended service on August 31st. However, I'm pleased to announce that the game has been fully preserved on Flashpoint, an open-source platform dedicated to archiving Flash games.
This preservation effort was carried out by Flashpoint archivist ThePowerPlayer, who played through the game multiple times to ensure the successful extraction of every asset, including those wacky cutscenes. If you have no earthly idea what I'm talking, give this a watch.
To experience Rockman 20XX once more (or maybe for the first time), download the latest version of the Flashpoint Infinity installer here. A Windows-based system is recommended, although limited support for Mac and Linux is available. If you run into any issues or glitches, drop a comment. I'll pass it up to the chain!
Many thanks again to ThePowerPlayer for seeing this one through!
