to answer your first question. i 'm not entirely sure. from first glance, i thought the SP's regular screen(no light) was extremely dark, darker than the original. but upon further reveiw, think they're the same. but i'm not positive. i don't have my old GBA anymore so i don't know. just be glad foir the SP. as for your second question, i have no clue. i'm not sure if this post was helpful or not. oh well...
