Hi, I'm in the process of doing this myself with LSPDFR but I'm finding it all very unstable after installing more that 40 vehicle's plus all the emergency vehicle's.
I've got gameconfig and all the other normal files and the game runs mostly good when not playing in LSPDFR.
Are you using LSPDFR?
What file's and figures do you use to make it stable?
Any help will be greatly appreciated
