Ripping from Blaster Master Zero 2

[ACrashinTime]

I'm trying to rip some textures from Blaster Master Zero 2 but all of the base game files are just in the file format and I'm not sure if there's a way to convert them.
I read some other threads and they said they just used ninja ripper, after trying that most of the ripped sprites seem to be all black (most likely indexed ingame?) and I get color palettes.
Copen's sprite is used as an example below. It also doesn't seem to rip the over world (blaster segments) sprites of the characters.

Thanks in advance for any help!
