I see, though I only had a short look at the code. So the SWT UI target provides native SWT controls for J2ME applications (i.e. not only native controls for the MicroEmulator itself but also for the J2ME applications run inside the emulator), right? This could be an interesting project.
What do you think would be more practical - to adapt the old code, - or to start over from scratch? Of course it would be a good idea to take the old code as some starting point. It's just I don't know how much has changed during the past two years and how well the old SWT UI code integrates into the current MicroEmulator version, if at all.
