How-to crack X-Plane 6.30
Used disassembler W32Dasm version 8.9

1) disasemble X-Plane 630.exe
2) find string "I do not detect an X-Plane 6.0" - is in the location code.txt :0046A776
3) function called from addres :0046A6C0 - call 0044DE32 is function, that returns in register EAX "00000000", if not in the CD-ROM original CD and "00000001", if found in CD-ROM original CD.
4) is demand ensure, that the function "function.txt" always returns in register EAX "00000001".
5) return from this function is possible from this addreses :0044DEF8(U), :0044DF24(U), :0044DF50(U), :0044DF6E(U). In 3 first addreses is (one instruction back) mov eax,00000000 and in the last is 00000001.
6) in this 3 locations :0044DEF3, :0044DF1F, :0044DF4B is demand this code: "B800000000 -- mov eax, 00000000" replace this new code: "B800000000 -- mov eax, 00000001"
7) In hexaeditor are this codes at there positions 4D2F3, 4D31F, 4D34B  replace this "b8 00 00 00 00" herewith : "b8 01 00 00 00".

thats all;
