Nes Buyers

How do you get emulators on your DS?

Yeah, I know the DSi is brand new. I was wondering if there were buyers of Japanese DSi who found a way to put emulators on the system (other than homebrew ... too much money). I speak particularly of the NES / SNES / GBA. Any advice? Thank you in advance!

It is (probably) too early for people to create software for the platform, which quickly. Watch this space.
