WOW....
Certinly an impressive ammount of replies.
So, here's my 2 cents!
As for the name, Amiga is copyrighted, so call it something original like:
The Miggy 6000?
Or just call it Agnus?
We all know what they mean, and it would be a cool inside joke!
As for Dreamcast compatibility, that would of been cool a few years ago, but aim higher- the Gamecube would be a more realistic goal. The disks can be read (with a little tweeking) on any DVD ROM drive.....
Best of luck on the new project, I wish you nothing but the best, my friend!
