I got a game that's in .jar I wanna play but I can't seem to find how to do such. I've read J2ME is a java emulator but seems I can only get crap off their site. Any ideas?
You can download it from the market. See the bottom of the first post here for instructions on how to install and use it.
I have used it for past couple of months - but the latest update has made a number of my java apps stop working, while others still work flawlessly. I have sent bug reports to developer so hopefully this will be fixed shortly.
