Yeah yaksplat - I figured that would be the proper procedure - still - should I upgrade? This latest update of MAME seems to be a fairly big step from mine.

Effects to simulate the appearance of an old CRT on a modern LCD monitor has been added, but it requires a reasonably powerful computer & video card. Some of the games now give better descriptions in the menu where you map buttons. They say "High Punch" instead of "Button 6"
As far as games, I've said this in a bunch of other threads, but a few of the PGM games added in v.146 made it worth updating to me.
Search MAME PGM on youtube and see if they are worth it to you. I think I had v.137 on my machine before and don't remember anything making me want to update it until v.146.
Be wary of v.147 as the midway games (mortal kombat) were broken.
They are back and fine in v.148
If you hold out a bit longer, there may be some video effects to simulate the glow of vector monitors (tempest, star wars, etc)
I keep the newest main release and MAMEUI on my laptop so I can check out the things that have been added.
