Has anyone figured out how to use LEDspicer with MAME to automate which buttons are used per ROM? I have LEDspicer running but can not for the life of me figure this out.

@OneSwitch glad it worked for you too!

@GreenHawk84 - I think the vector code for mame2003 and mame2003-plus are pretty much identical now. One thing that has changed is instead of a vector resolution multiplier of 1, 2, 3, etc. it will be the actual render resolution under the Quick Menu -> Options settings. If one of the core resolutions match the native native resolution of your monitor it should like decent. If you can't match the resolution to the display exactly then shoot for something close. I find using an HD display (1920x1080) that 1440x1080 looks decent for both horizontal and vertical vector games. Try a vector beam width of 1 or 1.2 (Quick Menu -> Options) and if it still doesn't look satisfactory try turning on bi-linear filtering under Settings -> Video. Some of the options require a core restart, basically exit the game and restart it.

@hsamuels Same problem after update 1.7.5 - MAME 2003 (0.78) 95bb558 I'll open a new topic.

@smeffron Thanks for the compliment. 😊 The kit I used is linked in my opening post right after the first two pictures. It's this kit from the German vendor Arcade4You. I used no t-moldings, as this kit doesn't have pre-milled notches for them. I just bent the car foil around the edges as it is shown here: The small round corners of my cabinet gave me some trouble, though, as you can see on my pictures in high magnification. They have some small wrinkles, but I can live with this little imperfection of my own work. 😌 You can also look at ArcadeWorldUK for more Flatpack kits. They have increased their product range significantly since last year.
