So in an interview a few months back before the release of Fever (::cough::title update::cough:

, Michael Yum had something VERY interesting to say about converting Technika to something tangible on home/portable video game consoles.
(Taken from The Escapist interview, Dec. 9,
The Escapist : News : DJ Max Interview with Michael Yum of PM Studios)
"Yes, exactly, we started developing DJ Max Technika even before the iPhone really took off. We didn't even think about Nintendo DS. There's a lot of piracy in Korea, especially for the Nintendo DS. Sure, it's bad with the PlayStation Portable as well, but not nearly as so on the DS. In Korea, a lot of the hardcore gamers have the PSP, but there are also lots of people buying them to watch movies on the subway, or television using the TV tuner, stuff like that. But with the DS, even the most casual users are buying these R4 chips and bootleg games.
There is a possible port of DJ Max Technika coming in the future though. We're currently developing a title for the Nintendo DS and experimenting with the iPhone as a possible device. Should everything work out then we could have a universal ranking system for Technika. Maybe some players will want to play it in the arcades because they can pull off the chains better than on their DS, stuff like that. We still have a lot of work to do on figuring it all out as with the Nintendo DS, it only allows for one touch at a time. The screen is also very small and everyone is worried about how the graphics will turn out. We don't want to dumb down the game or anything like that, so we've got some work ahead of us."
It's been eight months since then, and I've been wondering- how's that project coming along? Has it been sidelined? Canned? Or could it still happen? How would WE make it happen?
Basically, come up with your own theories, conjectures, or otherwise "things you'd want" in this title.
My theory: There's two limitations for Technika DS - lack of multitouch and lack of a larger screen for two lanes.
For the lack of multitouch, you could either remove coupled notes, or simply map an extra button to the L or R trigger, making you press and tap when a couplet comes up.
As for the screen size, there's two ways to tackle it: separate the two lanes into top and bottom, forcing the player to play just one while the AI plays the other (I think this is more arcade authentic but less intuitive for the player), or rid of the lanes altogether and make the beats just appear anywhere on the screen, a la EBA/Ouendan/Project Diva.
As for graphics and sound quality, I don't see why the DS couldn't competently keep up with first gen DJ Max BGAs. And to be honest, I would take a hit in the graphics department in order to play Technika on my DS. I'm pretty sure anyone would.
