I've created a new mod for Halloween. This mod features spooky re-skins of the characters default skins, a new unlock-able ghost skin for each character (simply visit any levels Skin Shop), a new spooky re-skin of the player's default cars, and several settings to spookify Levels 1 to 6 as you see fit.
This mod requires Lucas' Simpsons Hit & Run Mod Launcher 1.12. See this thread for information about 1.12.
This mod is decompilable and you can play around with the source code by right clicking it in the Launcher and clicking "Decompile".
You can download it from the SHAR Mods mods page.
