I know that this is an old topic and have no idea if Rollermacka is still around, but I just want to respond to this.
I think that the Jag's timing was a little off. It could have went up against the SNES and the Genesis, if it had been released during those early times. Of course third party support would have been required. That is something that the Jag lacked. At the time of it's release, third party was interested in bigger profits from Cd's and the opportunity to have the freedom that the format gave them vs limited space that expensive carts gave (Playstation and Saturn). The industry was ready to move on to the next generation of gaming. They were turning away from ROM cart use. (Two years later,N64 was an exception.) If the Jag had started as a CD based system, it could have had a slight chance. I think there was some poor judgment in interpreting the market at the time by those that were in control of Atari.
From everything that I read, I understand, the system was very difficult to develop for. (If that is so, then why is there homebrew games being made for the Jag even today?) If only the system had focused on arcade games. Games like Tempest 2000 and Defender 2000 make the system worth owning for me. From looking at the games that were released on the carts, the system looked like a high end super 16-bit game machine.
Interestingly the Lynx was more successful than the Jag and had a lot more game releases.
