I really only need it for 2 emulators - MAME2003 (in the arcade folder) and a game made in Python3. Is there a way to have it so I won't have a separate display with only the one game? This is for an arcade build and I'd like it to be as streamlined as possible.
edit: would something like "attract --import-romlist mame.lst --import-romlist python3.lst merged" work (put the two together in a new list called "merged")? I have a MAME 2003.txt file, but can't find a .lst file anywhere. And would I need to change to a certain directory, or can this be done from the home folder?
