Anything to me will look better than a massive system flag like that
Title (19xx)(Publisher)(TI-73-TI-81-TI-82-TI-83-TI-83+-TI-85-TI-86-TI-86-TI-89-TI-92-TI-92+)
Anyway even if there was something to represent all TI systems, taking one of them out would be a problem again, that's why i asked if that is possible (a set that may work across so many different systems/models) and if you or anyone doesn't have any great suggestions to this problem.
My first idea was to have different dats like what happens currently (but with some dats for more than on system if they are really "compatible"):
Texas Instruments TI-73 - Something
Texas Instruments TI-81 - blabla
Texas Instruments TI-82 & TI-83 & TI-83+ - blabla
Isn't this really doable? It really is strange to group so many systems in one datfile so that system flag would be needed, other opinions are welcome
