I just got the Tiny Arcade and after updating the menu software and loading new games on the SD card I saw that some of them were getting stuck on the green line. The only games that worked ok were Tiny Run, 3D demo and Drive demo. Everything else was getting stuck. I found this forum and read the last post and looked for the file TinyArcadeAllGames.zip. It was not really evident where it was, I had to do some searching. Nevertheless I donwloaded it, moved its content on the sd and nothing really changed. Green line and stuck.
Then I looked for the second file TinyArcadeDnew.zip mentioned there and that is the one doing the trick. So, if you copy on the sd card the content of TinyArcadeDnew.zip everything works. Now, it was not easy to find it at all. I had to search it on google and found a reference to a link from Amazon Japan...! Maybe I found it the hard way, but I could not find the link anywhere else. So, here's the link for anybody that might find the same problem and in need of getting the right files.
