Test Results

Selected Test Results

What works

  • Emulation
  • Memory viewer
  • Log
  • Options
  • Emulated keypad
  • JSR75 emulation (File system) - Just like on Windows¹
  • Emulated sensors

What does not

  • SWT-GDI+ mode has poor performance, use AWT-Graphics instead
  • Application crashes with SWTException if it's quickly zoomed-in right in the right corner of the screen
  • Application freezing and/or SWTException might randomly occur with random MIDlets. The affected MIDlets seems to change time-to-time ²


What was not tested

J2ME is a huge platform, so i couldn't test every MIDlet

Hardware tested


  • GPU: Intel
  • Driver: open source

Additional Comments

Prolonged tests were made to find out about SWTException bug on Wine 6.20 for over 1 week, the application didn't crashed on startup anymore but i'm not sure if this problem is gone.
KEmulator doesn't need special configurations anymore and now works out-of-the-box

¹JSR-75 works under restrictions of KEmulator's bugs that also appears on Windows, wich limits it's compatibility with MIDlets that needs it

²The cause of this bug is still unknown and may be hard to be detected, very long tests are needed. However, it seems to be affected by screen boundaries. Check Comment 8 to Comment 10 in bug #51924
