[Other] Fire Red: Buggy Battle Background

[negative]

Hey everyone, I have a problem, when it comes to inserting a battle background.

I tried it before and it worked perfectly. I used Fuji's tutorial found here.

This is the first good result after the palette change:

Spoiler:

The problem starts when I want to insert a battle background for the caves, so rocky backgrounds. I Used the same technique to insert the background and the .raw file, but when I test it, it comes out like this. Does anyone know what am I doing wrong ?

This looks eerily like an image in 8BPP mode when it should be in 4BPP mode. Are you sure you inserted the image correctly?

Yes, I used NTME and the image should be in 4BPP, as it showed in the program. I inserted the tileset and tilemap in their respective unlZgba numbers, like I did in the previous grass battle background.
