First off, this is not my idea, it originated at PZC which most people there apparently forgot AGN exist.

Yeah...nothing like PZC causing a pop-up that wants to install something even though I click Cancel...perhaps you could quote whatever it is you're wanting us to see?

They want to port ZC to the DS, which would be cool, but it's not gonna happen unless ZC is rewritten almost 100% from the ground up with the DS in mind.
Ignoring such tiny details as the need to port the entire Allegro and sound libraries, the main problem is that whereas the DS supports cartridges with a huge amount of ROM, it doesn't have all that much RAM.
And the ZC player gobbles up as much as 70 megs. And that's for a small quest.
