a quick word about the number of faults :
yup, in TE2006, in higher difficulty levels, there are not enough faults; I'll change that in TE2007, but it won't be same than in real tennis, coz there are just too much faults in real : in most matches, there are more faults than winners, and it wouldn't be exactly fun to play in a video game...
If for you Master is too high, and Pro is too easy, then you could try to raise the Pro difficulty, by lowering your skills in this mode (you can change the lowering rate in the Tennis.ini ).
Top spin = b1 + down ==> The more long time you press down, the more effect you'll get.
>> CPU can make shots which the player physically cannot do because of the control system
If it wasn't the case, it would look too unrealistic...
The CPU is also a bit less likely to hit a good shot when he's running... It's not very noticeable, but it's the case.
If you don't have the latest version of TE2006, be sure to download it : I lowered a bit the jump speed of the CPU (and the human's one as well)
I also just tested the acceleration against Master CPU, and it's true it's too hard to do a successful one..!
So I'll lower the CPU reflexes a bit for the next update, on which I'll work after have finished to port TE2006 and TEM to Mac OSX (hopefully within 3 weeks)
