Hello to all! I am kinda new to this. I'm working on building a 4 player mame arcade cabinet, and now I'm hitting a bit of a "speed bump". I've tried to look up as much as I can about this (which isn't really much to a noo-b lol). Here is the problem: There is one rom that works well with a version of MAME32, but not at all with the other version of MAME32. ** I am trying to get GameEx to run the rom in the correct version of MAME32, with all the other roms running of the other version of MAME32. I am still trying to figure out the Mapping Magician that came with GameEx. So here is my question - How do I do this (**) in noo-b "english" by using the Mapping Magician? (Almost like a more simple step by step version) How would I get GameEx to recognize two different versions of MAME32? ... And on a seperate subject (to keep from starting a new post...) - Is there a way to adjust or customize the "launch time" during when GameEx exits to launch a specific game? I am having trouble when launching Minecraft through GameEx. It does launch, but it takes a little longer than most other programs, which leads GameEx to return and leave Minecraft in the "background". Thanks in advance!!
