Hi, My son has a new ds and wants to get some games in Bali. I asked our contact for dvds in Bali if he had them and in his email he said he could sell us an r4 card for nintendo ds ("must preorder to java first") - have no idea what that means??? and 4gb memory card with about 300 games for Rp 650,000. Have also read on the forum that you can buy games at Matahari toy dept. Would be interested to hear other peoples advice as I don't really know much about it!! Thanks
