NFS U2 savegame edit info

Post by jeffareid »

It's an old game, there's no online play anymore, but in case anyone is interested, here is some savegame info. Mostly for ecu + turbo tuning, and adding unique peformance parts to career cars. The savegames don't have a checksum, so you can just edit a file directly. I have more info for the Corolla and Navigator because they are what I used for career mode.

Code: Select all

ecu and turbo tuning are a series of 9 bytes (max-min == 64)

Hi jeffareid, could you tell me on what I should be looking for through the hex editor to find and edit the ecu, turbo, engine, and nos for my career cars and custom cars? Thanks in advance!
