I just recieved my r4igold in the mail yesterday, and everything seems to be in order. I've opened her up and verified that it is indeed the card from www.r4ids.cn . I downloaded the wood 1.21 from that website, extracted the files, and placed them on the root of my sd card. I am able to boot into wood, and even run a few games such as superscribblenauts and new super mario bros. I can't seem to get zelda: phantom hourglass working properly though! I've tried to different files and though it loads ok and shows me the opening cinematics, it shows nothing but a black screen afterwards with garbled sounds. The file is 64.0Mb big. I've seen something about a 'file trimmer' on the cn website: do I maybe need to trim this file?
