Hello. I am new to here, I am a longtime launchbox user. I made a little pause menu program a while back and a user had messaged me and requested I take a look at getting it to work for attract mode. You can see my menu post on the launchbox forums here:
https://forums.launchbox-app.com/topic/55355-chadmandos-super-pause-menu-64bit-windows/.
I have fiddle around with attract mode and I have been able to get some success making the pause menu work with it, i have only played around with the mame emulator so far. I'm not sure how much I want to pursue this but I wanted to see if there was any interest. I'll see if there's a place I can find to upload it for everyone and post a link here.
EDIT:
Here it is on github
https://github.com/Chadosaurus/Super-Pause-Menu with instructions on how get it working with attract mode. See the readme.md instructions in raw form.
