nice review.
i was thinking of getting either the g6 or the supercard lite.
i was on the supercard store site, and on the top it said:
"one card to rule them all"
I was thinking of getting an g6 too, but the reason I chose for Supercard is that it has MUCH better homebrew compatibility. All the homebrew that tries to access the flashcart doesn't work for G6 so that's no DSorganize, no NDSMail, no BEUP, you can only save to the SRAM with Draw, no REIN and so on. Supercard can do all this, and I wanted to use my ds lite as an mp3 player too, so 512MB was too little for games+mp3.
