ROM Hack (Help) DOA: Dimensions Rom Hacking

[GoldenBullet]

I decided to try some hacking but I ran into a problem.
I can't open the .bcmdl character files in DOA dimensions. But I can open the .arc files which are in the sprites folder.
I am using EFE.

Character Files:
.bcskla
.bcmdl
.bacs

Do any of you people have the same problem?

You probably can't open them because they arent supported formats that someone has decrypted, and made a plugin for yet.
See if anyone has the format for these, and if not, you'll need to do your own hacking of these file formats.
