Ninja baseball Batman issues

[MrBoolean]

Hey I'm using Mame4Droid on my ADT-1(Android TV) and I can't get Ninja Baseball Batman to work, I keep getting an error stating that I am missing some CHD's/Required files, I have the rom and the parent rom and I still have this messag. Thanks in advanced.

I think it might be "Bat Man".

The problem is with the rom on this site
Try downloading it from somewhere else. Romhustler one worked fine for me.

Hmm for some reason it still requires the parent file, I have both nbbatman.zip , and nbbatmanu.zip . Those are the required files right?
