256 color mode on windows 2000

Hello everybody, In my windows 2000 operating system, there are only 16 colors, I have searched, a driver for my nvidia geforce gt640 videocard, but the search does not return any results. is it possible to somehow increase from 16 colors on the adapter to 256 to run full-screen games, methods that I found only for virtual box and Oracle machines, i me a system without virtual machines.

You have to install Blackwingcat’s Windows 2000 Extended Kernel and modified Nvidia GeForce driver.
