Roland Lieger has announced the release of
Power20 v4.0, the latest edition of his emulator for the once-popular Commodore VIC-20 personal computer.

According to the developer, Power20 v4.0 sports new features, including: Power20 now supports OpenGL. This makes it possible to scale the emulation window to any desired size (not just single/double/triple etc) and actually use the full screen in Full Screen mode without any black frame around. Using bilinear filtering with OpenGL produces an excellent, soft image. For those Macs that do not have OpenGL hardware support, drawing to the screen has been drastically improved for screens with thousands and millions of colors. Drawing of scaled images is now much faster. It is now possible to have Power20 draw directly into the Video RAM. While this is definitely not good MacOS practice, it is slightly faster than the legal way with CopyBits() that Power20 used up to now. This trick is even possible under MacOS X. Documentation is now also available in HTML format. Since DocMaker is not Carbonized, reading the Power20 Docs under MacOS X used to require a start of the classic environment. Now they can be read in any Web browser. Power20 can now be used as a screensaver. Let Power20 play VIC-20 demos (loaded from RAM Snapshots) while you are away from work, or let it show slideshows of old games, cover images or Commodore ads. Lots of minor bug fixes and enhancements.
Power20 is PowerPC-native, and is available for use with “Classic” Mac OS as well as a Carbon version, for Mac OS X. The downloadable version is restricted to 10 minutes per session until you register. Registration costs $15
