so is a hex editor easy to use? it kinda sounds it. it just sounds hard to edit.

Yes, there's no reason why hex editors can't be very easy to use. It's knowing what numbers to type that's hard.

ok one more question. i am going to work on it today but i just have one more question. for editing levels, or characters or whatever, what file should i edit, the .exe, the savegame, (or i might open a different one)? if i edit the save game kon tiki, how would i make the program? i could just keep the save game file with the game when i put it on a cd for my cousin. it automatically saves and stuff, so if i just made it with the save game file already in the folder, it would have the stuff needed correct?

or would i be better off editing the .exe file.
which one would be easier and which one could i do more editing to.

also i dont really get the numbers thing. how do you know what numbers = what letter again? is there some site that explains this?

thank you again for the help.

Joey, I'll put a step-by-step tutorial, with an example, and a step-by-step tutorial on how to make that little program later, when I have more free time, ok?

well you dont have to. im in the thing and it shows all the numbers and stuff, then the text next to it, but most of it is just random letters, numbers, and other things, so i have no clue what exactly to change nor what each thing means. plus i doubt i can edit levels with this :-\

You can't. What Kon-Tiki means is that you could change save games like if you save game in an FPS and you have 100% health and 8 bullets of the second weapon, you could search for 100 and try to change it to 1000 and see if it works... In Lego Racers you also could change player's head and bodies (not create new ones, just switch them).

by editing the numbers you mean...i really wanted to edit the levels...any way i can do that?

You'd have to ask the developers of the Lego Racers game. To work it out for yourself you'd have to reverse engineer their file format.

im not even going to ask how to do that thanks for the help though guys. ill try messing around with it a bit later.

Look into C++ game moding. It's relatively easy if you know the game engine API in and out and know the algorithms used.
