I was hacking Rockman 2 when I got this

I have no clue what happened except that I was changing palettes in clash man's stage.
If anybody knows how to fix this please let me know, thanks

Manually (nah) or with an editor (which one)?

Hm... Well, I don't know what might have caused it then.
But when I encounter something like this, I usually use 2 FCEUXs with the in-built Hex editor and Code data logger opened in both emulators.

1.) Open 2 FCEUXs with the original ROM and your Hack.
2.) Open Hex Editors and Code Data loggers.
3.) Start the Code logger in both on title screen, then reset both games.
4.) Stop the Code logger after the intro.
5.) Compare the highlighted data in both Hex editors.
6.) If you find any difference, copy the original ROM's data and paste it to the same location in your Hack's Hex Editor. (do NOT save the ROM)
7.) Reset ROM and check if it works.
8.) If it's working correctly, save the ROM with FCEUX's Hex editor, or do it again with HxD or any other editors.

It always worked for me before.

Well, I'll try to reproduce it.

Well I tried it and it didn't work, all that happened was the text went back to the japanese or it did nothing, so now I have no clue what to do

Copy 1CA10-1CA8F from RM2(J) to your ROM. It seems you've messed up the data here somehow. I think.

I don't know then. Maybe it's the TSA data instead...
And what about 19010-1a00f?

[EDIT]No, that is not it. It's 1C210-1c30f. That's something that looks like TSA data to me. But it isn't either. It's not for the building...

This is the last that might be it: 1c010-1c20f
If it is not working either, then the problem is with the PPU or something. I dunno.

No prob. I recommend saving these offsets in a text file in case this happens again.

[EDIT] I made a small patch that fixes the building whenever it get's glitched. May not work if Structure data is corrupted.
