The guy just made it compatible for DS today! (8-5-07) And all because I asked for it.....a CF/SD speed tester for DS and GBA flashcarts! WOOT! I haven't actually tried it yet (got to go pick up our new refrigerator in a few minutes) , but my guess would be that it is what I asked for in my other thread here: http://gbatemp.net/index.php?showtopic=56874&hl= Here's where to get the tester program: http://www.pineight.com/gba/#cf_bench Made by a dude named "tepples". Now we'll have to start a new thread benching all our different cards.....but I gotta go right now. Arrg!
