Opera DS Browser Package

I'm not sure if you kno this , but the new Opera browser set to release in Japan on July 24th come with an expanded memory cart. sweet right? judging by the fact that theres 2 editions, DS and DS Lite, im willing to bet that they're 2 diffent sizes to fit the short cart DS Lite style. even sweeter. now i just need a homebrew cart to fit my Lite and we'll be set.
