Esmertec Jbed 3D mod - Java with file system access, full screen mode, 3d, 8mb Heap Size!
This one works great on my HTC S710...
Can be installed to storage card, so you don't have to worry of running out of memory if you install many java games and apps
If you install this Jbed to storage card, all the j2me stuff you install will automatically install to storage card.
This version runs very fast, great for games! Also runs every 3D game I've tried so far!
Of course it's true fullscreen aswell (Great for Opera Mini)...
I've just tried the new Opera Mini 4.1 Beta which allows saving webpages & files within Opera Mini (now Opera Mini doesn't have to launch a separate browser just for saving!!!) and it works great! So that confirms Jbed has the JSR-75 support that is needed
First file is for WM6 devices, second one should work on WM5.
