The sections are divided by game, obviously. Passwords for the endgame are provided at the bottom with the exception of ■Rockman《☆》Megaman■ which did not contain a password system.

Something to Remember
Do not forget about the Mega Buster when facing bosses once you have other weapons. Just because a boss is weaker to another weapon does not mean that weapon is the only or sometimes even the best solution. There are several instances where I found the Mega Buster or a Rush Adaptor way more useful than the actual weakness. If I listed the mega buster in the weapons to use, it is because I found the boss is actual weak to it or it was incredibly easy to use it over the normal method.

~☆》 For those who are playing both collections, I also have a guide for the second.
