Thanks for responding, Manu!
Yesterday, (2/25) shortly before Solarisaint said he would send me the "correct court.ini", I actually got the clay court to finally load correctly (with the proper clay court sounds & ball/flight characteristics) by placing the clay "court.jpg" into the "court01" folder/directory (just as you said...)
Something I'm still not clear on, though...is the "court.ini" a separate .ini from the tennis.ini?
I mean, where is it placed...in it's own folder/directory, or in the tennis.ini?
p.s. Thanks to you also, Solarisaint...your courts are TOO cool!!
(I'm think I'm ready to tackle the WImbledon court now... if you will send it "as a jpeg", please)
