Tandy compatibility methods (strictly Tandy 1000 and not IBM-PC compatible, FAT executable, separate executable on disk, separate package, separate disk versions in same package, separate boot disk with shared data disks, IBM-PC game claims Tandy 1000 compatibility in specs/reqs, versions differ in compatibility like Prince of Persia, combinations of these)

*In cases of Tandy DAC, this presumes other DAC hardware does not have superior DAC and voices. Some might. It is time consuming to determine which hardware applies. But, Tandy 3(4)-voice in this list is valid.
