RetroFE does not at the moment, but the individual emulators like MAME should support it. You can certainly use the feature in-game if you want.
Hey Pieter, thank you for the reply, much appreciated. I can stop looking for that as a solution for now
I have tried the MAME settings, and they are simply not working for me either. Plus I would like to do this for other emulators (M2 mainly). I will have to keep trying with MAME.
Just in case there is someone else here with MAME Marquees working, that may be able to shed some light on my issue ...
I am aware that you need to set MAME.INI for two screens and the two views (for CoinOps I have used "Bezel" and "Marquee" for the views in the .INI), also the .LAY files with the element for the marquee .PNG file and a "Marquee" view set (tried with and without screen index set). The Bezel shows fine, just no marquee (all .PNG files are in the emulators\mame\artwork\machine name folder). This is on Windows 10 (1909). The monitors are a 1080p 16:9 for the main display and a 14.9inch LTA149B780F 1280x390 for the marquee (had to set a custom res with scaling in the Intel control panel to obtain the correct aspect ratio as it defaults to 1280x720). The monitors both work fine in Windows, so assuming that is all good. I also tried MAME Hooker, but this too failed for me. I had to jump through a number of hoops to get it working on Windows 10 (additional OCXs, running as admin), but got it all working (I think). It doesn't generate a log file for diags though, so I gather something is still not right. I've attached images of the mame.ini and default.lay files I have setup.
Thanks again,
Trevor.
