Pre-ordered for two new Atari Jaguar games have just opened on Atariage: http://atariage.com/forums/topic/283125-defender-of-the-crown-and-treasure-island-dizzy-arrive-on-the-jaguar/
I’m gonna go out on a limb here and say that these games most likely use the Motorola 68000 processor built into the Jaguar and not the main Tom & Jerry chips, resulting in a more 16-bit look. Still, it’s fun to see people continue to develop for the Jag and to see brand new complete-in-box games be released!
