I have used NesterJ 1.10 for about a year now, since I found it runs smoother than 1.20, and I don't have any friends who'd play wirelessly with me. Recently, the menu system stopped working. The "Up" function is stuck on, because the menu won't let the selected game go down. I have a way around it, but it's a huge pain in the ass, and would prefer not to have to load a rom, struggle back into the main menu, and choose the game I really want to play every time. It may have to do with the Pandora format of the memory stick in question, since it runs fine on my non-Pandora memory stick.
