You have to bear in mind that they do not say that this slot 2 device supports GBA so you can´t knock a product because it doesn´t do something they don´t advertise, it is like saying "I´ve bought this flash card and it doesn´t play PSP games so it´s crap". The score relates to how well the product does the job that it is supposed to do. If you want GBA support, buy a flash card that is supposed to do that.
