Yes, I get that but I was talking about the deprotected games that are stored in DOS-order (DO/DSK) images.  Those surely are not as varied I would imagine.  I am trying to see if there is a deterministic way of detecting an 6-by-2 RWTS in a more generic fashion than my previous attempt used in Apple Game Server.
