http://www.neoflash.com/ looks kinda cool, i was talking to the guy and price for the 512 will be $180 and for the 1024 $230, he mentioned that emulation was so easy and that they could easily do snes and nes... , you can run gba code and nds code, sweet little thing indeed.
So what is it? Just a flash card like the ones that have been available on the GBA for quite some time? Yakumo
it looks to just be using a cleanly built pass though that you can get for $20 and just use an old gba flash cart. dsdev.org
Great deduction mr homes. So can you with a passme. (sorry not being an ass, just felt like saying that, blame stupid detective conan anime). as far as i know ATM only 2 roms are out (sonic is fake), Mario DS & Metroid demo. --edit-- This and the Passme are based on the work darkfader did hacking the DS.
