virtual memory

OPENCP usually needs more than 4MB memory. If you have 4MB or less you can still use the player if you enable the virtual memory functionality of the dos4gw.exe protected mode extender. Just as windows it can swap your memory to hard disk and thus provide more memory to applications than physical memory is present.

To enable use of virtual memory simply place the following line in your autoexec.bat or type it at the command line:
set dos4gvm=1
