Thx for the replies!! fyi, i did not trim any of the roms, just drag and drop. I don't think they are corrupted either, at least to my knowledge, although i use the sd card reader that came with the r4 (if thats a problem). And i am using a 1 GB sandisk taiwan therefore that might be the problem. Also I formated the microsd using FAT16/64k clusters I am going to buy a toshiba and try it. If that doesn't work i am just gonna return it and incur the losses... o yeah i bought this at echostore.com if that matters. I don't know their reputation for quality products. Overall I can't play any games becus I never know when it will freeze. so far i havent gone more than 45 mins before a freeze up.
In FF3 and other games I play, the game will crash and both screens will freeze but the music usually continues to loop.
I will update if there are any improvements.
