hello everybody
Ok, well I don't have the answers on above, but check out Tsunami 2010 (can be found by google pretty quick). Its a really nice remake of Tempest 2000.
Runs great, you can even download the Tempest 2000 soundtrack for it.
I'm fairly sure above is right about T2K on the Jag, I did read somewhere you could use a spinner... now I may be completely nuts, but for some reason I think you can stick the old atari indy contollers into the port and they work (I may have dreamed this, my apologies if this proves to be way off base).
Here was a description from the Tsunami readme file

celebrating the upcoming 10th anniversary of
yak's mega-superb jaggy-t2k (which is still
one of my all-time favourite games!) and
making one of my oldest dreams come true..
(=coding a totally new t2k-pcee-rmx-conversion..

there are a LOT of differences between
the old jaggy version and this one..
not only concerning the gfx+rendering, of course..
(although these are the coolest new features.. =)
(100!) rmxd levels, (14!) rmxd enemies,

rmxd gameplay, rmxd everything..
