here is a simple tut by Enigma to edit most gamesaves, for example this is driver: open that save in hxd hit ctrl+g go to offset C000 click search again find data type Integer number 32bit double word big endian put your stat number in there n click ok (i was looking for 6824 from mada's save) change that value in hex: i have changed the value from 6824 credits to 999,999,999 credits close hxd resign/rehash done All credit goes to enigma for this great little tut
hopefully if the dev crew could shed some light on finding and repairing checksums in saves we could blast off big time
