Unsurprisingly...
These two new MIDP 2.0 games don't work on the Nokia 6600. Sad but true. You get to the main menu, try to launch the game based on your level, and nothing happens. This is not surprising.
I've actually run into some weird problems with my own little J2ME apps. The Jabber group-chat app I developed last summer (which should work fine now that sockets are an officially supported feature of MIDP 2.0) won't work because the app refuses to respond to a display.setCurrent(newScreen). Why?
Like I said before, I can't believe both Sun and Nokia allow this sort of thing to happen.
