Partial MIDP support on the DS

ole has taken my KVM port to Nintendo DS and added some updates. I haven’t played with it much, but he lists the changes as follows.

R3: New features added by Ole:

  • fixed the CLDC implementation (timer, memory size, system properties)
  • added support for reading of the PNG images (code taken from the PhoneMe project)
  • implemented native functions for rendering the basic graphics primitives on the screen
    (lines, rectangles, triangles, images)
  • added support for accepting the JAD files in the application browser
  • added the core part of the Pstros MIDP library
  • added VideoTest example to show how to draw on the screen
  • added ‘_rebuild.bat’ to show how to build and preverify the class files.
    Note WTK installation is required.

This is quite interesting if it is able to run some MIDP-compliant games, but we’ll need to do some testing to see how the speed compares to your average mobile phone.

UPDATE: He’s made a few more updates since I originally made this post. Be sure to check out ole’s site for the latest info and download links.

  1. For compliance testing I used the JBenchmark application. You can find it here: http://www.jbenchmark.com/download.jsp?benchmark=v2

    or you can try my game demo:
    http://www.volny.cz/molej/nb/NeonBeads_NDS.jad
    http://www.volny.cz/molej/nb/NeonBeads_NDS.jar

    Download both the files (.jad and .jar) and put it the same directory where you have installed the KVM.NDS. Then you should be able to launch the JAD file from the application selector of the kvm.
