I am selling a GBA with a CF Supercard, 512 CF, and a USB CF reader. Plus GBA Charger.
GBA has scratches on case but NONE on screen. Works great, battery is good (except when using emulation of course).
If you want it, please just make a reasonable offer.
Also, I will have the WiiKey presoldered to the Wii clip (other post) for sale, you can make an offer on that too.
