I have tried that Openwig.jad (wherigo player for java) and noticed that it almost worked. I can see internal gps working. I could open game cartridge. Only thing I could not was actually to play it... When I press start cartridge button. It just has some error message and I'm taken back in to OpenWig front page. I have posted that err. message to OpenWig developer

And he responded a while back.

He says that there is that error Cached signal 11 that should not appear. He thinks that it could be fixed on PhoneMe at first. So Is that something that could be fixed? Do you need more information. I think I had that 0818 version installed.
