CopyNESW is a 32-bit Windows application designed for interfacing with Kevin Horton's CopyNES, a Nintendo Entertainment System that has been modified to add a parallel port suitable for dumping cartridges, saving and restoring battery-backed RAM, uploading programs to RAM/Flash cartridges, and real-time debugging. Nearly all functionality of the original MS-DOS QBASIC client has been implemented (in one form or another), and it can be used natively on Windows 2000 and XP (and possibly Vista).

1. Download the QBASIC client for CopyNES (from official site linked below) and extract it to a convenient directory, being sure to restore the directory structure.
2. Download the CopyNESW client and extract it into the COPYNES directory.
3. Run COPYNESW.EXE. The menu should appear with only a small number of options enabled.
4. Click on the 'Options' button and select which parallel port to use.
5. Upon pressing 'OK' (and each time you start the program), a version detection dialog should appear for about a second. If you are using an older CopyNES (with version 1 BIOS), the delay will be longer (3 seconds) and the 'Microbug' option will be disabled. If you receive a warning about bidirectional communication, change your parallel port settings in your BIOS - ECP mode is supported (assuming your parallel port is compliant), though EPP mode may also work.
6. Read the CopyNES QBASIC documentation - a great majority of it is relevant to the Win32 version, and the rest should be fairly intuitive.
