Guitar Hero: On Tour and Sony Ericsson w580i cell phone questions?

Question

I know that the new Guitar Hero: On Tour game uses both cartrige slots, so does that mean that the game would use more power, and drain the DS battery faster? If it does, is the game still worth getting?

Also, for anyone that owns the Sony Ericsson w580i cell phone, i heard that the battery life on the phone isn't that good. Is it possible to buy a better battery for it, that provides more battery power than the standard battery that comes with the phone? If not, is the phone even worth getting with the standard battery?

Answer 1

i dont kno about the cell phone but w/ the guitar hero on tour, the game boy catridge is only reading info from the buttons you push down on the guitar grip so its not using anymore batteries than playing a normal ds game
