While the DS has its own collection of good titles, admittedly some of us will want to sample some of the games on other handhelds.

That said, we're letting you know of the release of Pstros NDS 0.7.1 - R5 Build, which will enable you to run  java programs and games originally meant to run on mobile phones.

The developer explains that this homebrew emulator was created by using a DS port of the Sun's KVM java machine, and an altered version of the Pstros MIDP library. Here are some of the changes that were implemented since Pstros NDS' intial release:

• version 0.7.1 - R5 build
• added HttpConnection class to satisfy dependencies of some applications
• implemented drawing of the ellipses (note: draw/fillArc is not fully functional yet)
• version 0.7.0 - R4 build
• Nokia UI api partially implemented: drawPixels and getPixels implemented for the 4444,444,8888 and 888 pixel formats with the full manipulation support (mirroring and rotation).
• bug fixes (JBenchamrkPro works now)
• version 0.6.0 - initial R3 build
• 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
• ported the core part of the Pstros MIDP library to use CLDC java machine instead of the fully featured j2se java machine.
  

Further details on Pstros are available in the file bundle readme. You may also want to visit the author's release site (via the source link below) if you're interested in reading an in-depth explanation of how the emulator works.
