The "TG" in TG settings refers to Twin Galaxies. They are generally regarded as the authority for high scores in the competitive video game playing universe. The TG settings are the settings you should have on a recorded game if you wish it to be considered by Twin Galaxies for recognition as a high score in their database and forthcoming Book of Records. The settings can be found at http://web.idirect.com/~cubeman/tgts.txt . If you can't find the settings for a particular game, just ask on the board here and I'm sure one of us can get the information for you.(posted 9478 days ago)JoustGod
