Like I said, I have the entire 198 rom set (non-merged) from PD ... so should include all the extra files that I could possibly need. I am first just testing everything through regular MAME before trying to get it to work in Launchbox. So I will figure that out at a later date. For now, I just want to get the MAME Intellivsion roms to run through basic MAME 198 - no UI.
I am a little confused about your wordings .. what do you mean by "when the interface comes up type Intellivision and it should be an option"? So I type "Intellivision" in the search area? And what option are you talking about; what option am i looking for? It almost sounds like you are saying I should move the Intellivision roms into a sub-folder and tell MAME to look there.
Also, I am confused at what you mean by "Do you have the MAME software list games". Can you expand on that?
Thanks
