DS Link is the first DS flash cartridge that fits entirely in the DS’s DS game slot. You won’t need to put anything at all into Slot 2! It even uses MicroSD/Transflash cards so you can load up with up to 2 gigs of games! Whoops, I meant ‘homebrew applications’. Yeah.
What’s the catch? Well there’s two, actually. First, it won’t play GBA roms. DS only. Second, it won’t act as a passkey – you’ll need to flash your firmware with Flash Me to make it work.
With that in mind, it still looks promising! DS Link goes on sale at the end of the month.
If you can’t wait that long and GBA games are important to you, the Supercard Lite is available now!
