I've been unable to get this working so far on my Jordana 540 - I realize you have only been able to do limited testing on this platform.
When the game screen appears there are no games within it - is this right? I can see them only after I have selected 'show all games'
I select a game and 'play' and I get a black screen for a few seconds before being returned to the game screen. I have reset the machine and have no additional applications installed. this lets me have 9M of free program memory. I installed the program(big) onto a storage card.
I hope it is simply the case that I haven't set it up properly. Do you have any advise?
