The problem with Addam's Family and Attack From Mars, and every other game with a dot matrix window, is that they are slow as hell on a low end PC.
All of the pinball tables at AJ's Pinmame site have a dot matrix window. So that means you have to download both the table and the roms. None of the games at IRPinball have a dot matrix, so you only need to download the table from that site. The tables at IRPinball are mostly pre-80's tables and run alot faster too!
"Visual Pinball" is the main program that you need to run all of the tables. If you want to run the dot matrix-tables (like Addam's Family) then you need to download the "Pinmame" program too. You have to unzip the tables folders in the "tables" directory in your Visual Pinball folder, but you put the roms folders in the "Roms" directory in the "Pinmame" folder without unzipping them. If you have any questions give me a hollar.
Deffinately try out this program, because its awesome!
