Hi everyone, and a HUGE thank you to Petar / Ryder25 for making these mod programs.
When modding these games be aware that changes may not take effect immediately. When I modded TOCA Race Driver 2 on the original Xbox I had to delete the save game file, inject the modded files, reset the Xbox and then put the save game back in. This is because once the game loads it puts the files into the cache and loads them from there, so if you change the original files they were ignored until the cache files were overwritten.
This is probably similar to what happens when you change things in F1 2013 etc, you may need to delete your profile, put the modded files in and then load up the game, not sure if you can use the same profile by putting it back in.
When modding the AI in the /tracks/difficulties xml files it wont change the career track difficulties only the season ones. If I change the ai difficulties in championsmode files, the game won't start for me, CM seem to have some sort of file checking system for that.
So your best bet is IMO is changing the files in the database.bin and we can all thank Petar for allowing us to do that!
