Product Description:

Use Power20 to run Commodore VIC-20 software on your PowerMac:

Power20 emulates all important features of a real VIC-20 such as:

MOS 6502 CPU Emulation (incl. Illegal Opcodes)
VIC (Video/Sound IC) Emulation (Video: Scanline-Based, incl. all Video Modes; Complete Sound Emulation)
VIA Emulation (Timers, Interrupts)
Optional Original VIC-20 Keyboard Layout or Macintosh Keyboard Layout
Joystick (both via real ADB Joystick and Keyboard mapping), Paddles and Lightpen emulated
CPU Level 1541 Floppy Disk Emulation. Can handle most fast-loaders and special floppy tricks
ROM Level 1541 Disk Drive emulated (*.D64, *.X64 and ZipCode files supported) for fast and easy disk access
Direct Access to Macintosh File System (both *.C64 and *.P00 files supported)
Tape Drive (Datasette) emulated (*.T64 and Lynx files)
TapeDisk: *.T64 and Lynx files can also be used on disk drives
Automatic expansion of ZIP, GZ and LHA compressed Disk or Tape images. No need to expand compressed images from CD-ROM to harddisk. Just run them from the CD. Power20 can also write GZ files, saving space on the Mac HD
Printer Emulation (Text only)

What's new in this version:

The inner guts of Power20 have been totally rebuilt. While previous Carbon versions of Power20 where just slightly tweeked sideproducts of the Classic version, there is now a Carbon only design. The link format has been changed to Mach-O so that there is now a clear distinction between Classic and OS X (and noone trys to run the Carbon version on OS 9 and is surprised by the absence of Input Sprocket joystick support). Preferences are now stored in (OS X standard) XML files. Please note, that while the main emphasis in the developement of Power20 has been shifted to OS X, the classic MacOS is still supported and has its own version of Power20.
The OS X version of Power20 now uses neat icons with 128x128 pixel.
USB Joysticks are now directly supported in Power20 OS X. USB/ADB joysticks have been supported in Power20 Classic since Power20 1.5, but the OS X lacks Input Sprocket (Apple's Standard for joystick support in Classic MacOS), so this feature was not available in OS X.
Joysticks now have seperate Single-Fire and Auto-Fire Buttons. That way you can easily to produce a single button-press (to switch to the next level) and still fry lots of meanies without hurting your trigger-finger or having to reconfigure the joystick.
OpenGL support is now much faster.
Power20 now remembers ten recently used disk/tape images. Changing the disk in a multi-disk game is now just a single mouse click.
All dialogs have been redesigned to comply with Apple's Aqua Human Interface Guidelines. Several old useless options have been discarded.
A problem with the floppy emulation has been fixed (Trouble using direct mode files)
All Menus and Dialogs have Help Tags (Balloon Help is not supported in OS X). Also Help Tags are supposed to be short (according to Apple), I have chosen to suppy long, informative texts.
If the Mac is equipped with a 2(-3) button mouse, the second button of the Mac mouse is used to directly emulate the second button of the C64 mouse. Users of a 1-button mouse can now choose the control-key that they have to press to obtain the second C64 mouse button.
All scroll bars (directory window, debugger) can be controlled using the mouse scroll wheel (assuming your Mac mouse has one).
The Shareware Info window is now resizeable.
