update
i m on the right track.while experimenting i found 5 different track address(driving chalenges have 5 track address).in menus some of the address get -1 value.i m combining these with new codes.
here is the result.
Loading successful but instead of the given track we get deep forest (or random i couldnt figure out) but the intended tracks map shows.i mean you race in the deep forest but track map shows (hong kong or complex string) yes i managed to load at least new tracks maps
here are the new codes(highly experimental )
0X0080F440 0X0000003E (DEC value 62 complex string)
0X0080F450 0XFFFFFFFF (DEC value -1)
0X016E4CC0 0X0000003E (DEC value 62 complex string)
warning :you have to use external camera .sometimes crashes but try couple of times
the red ones dont have in game track map
the blue ones have in game track map
