by default, it's Pro-10 ; it's not recommended to change it as I didn't test in other levels and some of the new stuff might not scale correctly with the different CPU levels.
However, if you want to try, edit Tennis.ini (or the .ini of your Profile if you have created one), and add these 2 lines under [CpuMatch] :
- Code: Select all
Diff = 2
SubDiff = 10
Then save, close and launch the game.
Diff 2 = Pro, 1 = Master, 0 = Incredible, etc. SubDiff is the SubLevel.
