The VG Resource

I would like to have the skyboxes that are from the stage "Mystic Mansion" thats from Sonic Heroes because i wasn't able to rip those stages but they are in a bsp format. Could someone give me the correct tools to get the models convert the renderware bsp files to a format so they can be editable?

And i need someone to add a tool that can open bsp files in any version including 11 and up.
