  • I want to build my own arcade controls!
I am using a weak PC to run MAME from 2007 in a cab.   It works well but all of my vector games have scanlines, Asteroids didn't have scanlines.  How do I get rid of them it looks awful.  Yes I tried shutting them off in the vector.ini and MAME.ini but they still appear.  I have tried everything I could think of but I can't get rid of them.  Even raster games don't show scanlines when turn them off but vector games still do.   I I searched online but could only find posts of people wanting to add them not get rid of them.  Is it a bug or am I doing something wrong such as miss a setting somewhere?

If you can turn them off for raster games, you should be able to do the same for vector games.   :dunno

Yes I tried shutting them off in the vector.ini and MAME.ini but they still appear.
There are other .ini files like horizontal.ini that could be the issue.

Have you tried making a game-specific .ini? (asteroid.ini)
- The game-specific .ini is the last one that MAME reads and those settings override the ones from higher level .ini files like mame.ini, horizontal.ini, vector.ini, etc.
- You can make a game-specific .ini by renaming a copy of the mame.ini file and editing the contents as desired.
- You can delete any lines in asteroid.ini that are unchanged from mame.ini and are obviously not relevant. (paths, directories, input options, debugging, etc.)  Removing the obviously irrelevant parts should make it easier to find something that may have been overlooked.   ;D
