MAME Question: Bezel Display

[zorrobandito]

So, I've worked out how to display some bezels but not others. Phoenix and Space Invaders, in particular, look fantastic. With MAME .136 I can switch between cocktail and upright as well as being able to zoom to get it to look just right.

Two Questions:

1. How do I get the bezel to display in Scramble, for example or Twin Cobra. I have the artwork zips in the same directory as Space Invaders and the jpgs work but turning on bezels in MAME (by pressing tab, though it is on by default from mame.ini does not do anything. It's a match for romset and artwork file.

2. How do I access the equivalent video display options in MAME .99 and .129? Space Invaders with MAME .99 seem to simply need the artwork file present and the bezels-on option set in mame.ini.
(The majority of my machine is built on these two flavours.)

Anyone M4M3 enough?
