"If older tech isn't used then why did Nintendo not effectively use the same CPU line for the Gameboy and another for the DS? So even if it was new when the Gameboy was released, it was old by the time the advance was discontinued."
If you don't use older tech, you don't use it for the new system. Why were you asking as though that would be the opposite.
As for the second sentence, the Gameboy CPU was only used for the Gameboy. Even the Gameboy color used an updated CPU to take advantage of the greater power available. The GBA had the GBC CPU, but only to accommodate backwards compatibility, not for the GBA itself, which was using new parts. The DS used two processors, both new.
So parts were not being reused, and it wasn't behind. It was what would fit in the specs at the price Nintendo wanted for the line.
A flashy-first game is awesome when it comes out. A great-first game is awesome forever.
