fixed my problem. i downloaded two files. the myth version of the nba 2003 no-cd and this other file that is found on this forum posted by one of the members. ok now do this .....
download the myth file at this link:
http://216.127.68.158/games/files/mytnl3.rar
download the second file, follow this link and find the file, its by a member called enexy
http://www.fileforums.com/showthread...threadid=39901
download that file, follow the instructions, download the .jpg file and once downloaded rename it as filename.rar.
ok now you have the two files, use winrar and unpack these two files. copy the ScanReg from the myth file and use the nba2003.exe file from the filename.rar file. dont use the nba2003.exe from the myth file, ok copy those and paste them into your nba 2003 folder. once done, run ScanReg and let that finish, about 10 seconds. once done, run nba 2003.exe and it should run fine.
good luck. later guys
