The newly released Rockman 3 in 2025, hacked with the name Rock Battle Cool, has undergone significant modifications in terms of art, gameplay, and music, greatly enhancing its playability. It utilizes the Japanese version of Rockman 3 and the Improved version of Rockman 3, rather than the American version of Mega Man 3.

You can record a video and send it to my email：[email protected] to help me check how this bug was triggered. I didn't find this problem when I played it myself.

I tried it on both versions, and they both have the same problem of clipping a bit of the wall instead of spawning directly in the teleport before the fight.

I made a savestate in the teleport refight boss room, and tried to see if the bug was just on the first boss I faced, but it happens on all bosses. When I go into the teleport and appear on the boss refight screen I clip a bit of the wall and fall into the teleport, I don't directly get into the teleport and maybe that's the issue?

How did you trigger this bug? I hope you can give the complete trigger conditions so that it will be convenient for me to fix it.

Hey YF_EC, I'm Really Liking the Game but I found a Bug when you Refight the RM3 Bosses in Dr. Wily's Castle. After Beating the First Refight Boss I Picked, the Teleport didn't Work and I was Stuck in the Boss Room. I'm Playing the Game on FCEUX Emulator. Hoping for a Fix, Thanks for the FUN RM3 Hack.

I can't get this to work. I tried "Rockman3 Improvement.ips" from "Megaman 3 Improvement Ver 310" from kujakiller and the game starts, but it sends me directly to Dr. Wily fortress.

This requires the improved version of Kujakiller's Rocmkan 3 not Megaman3

I can't seem to patch this one. I see it's asking for some IMPROVE ROM but I can't find any CRC-32 matching the one listed here. Any tips?
