The Re-Volt Hideout

I downloaded the game: Revolt, the compressed folder, and extracted all the files to a single folder as u said, the game loads and stops working when the final loading is going on, instead displays a message:- "can't flip display buffers".
I use Windows 7, pls help....

Sounds like you downloaded a version from 1999
Either get the game on https://re-volt.io/downloads/game or get the patch from https://rvgl.re-volt.io and it should work fine.
