Asteroids Deluxe Blue vectors

[challenger2010]

Hello, I have been chasing the documentation and posts to have blue vector lines for Asteroids Deluxe.

Setup:
Using Mame2003
Using correct .art file

I got a nice background pic, do I just need to add a blue overlay and update the art file within the zip file? Or is there something else that I just need to turn on.

Thanks!

Hello, any help? I made sure the priority was set right, transparency is off, vector lines look white while passing objects on background and the correct blue when passing black on background. I think it’s a blending problem.

Any suggestions appreciated:)
