I have every major Atari game system released, over 400 games, and a MegaSTE computer. I agree about the ports of certain game for certain systems. There have been ST ports for the Jaguar. But, they look exactly like the ST versions. That is because they are. The A5200 was really a 400/800 Atari computer. The carts were bigger for the A5200 to show that they were set apart from other systems at the time. It did not fare well because they were too incompatible for the other Atari system at the time, the A2600. I think they should have made the cart port the same size as the A2600, which is something they tried to rectify in the A7800, and mostly did. However, some A2600 games were still incompatible with the A7800. Unfortunately.
