I'll put it to you this way guys, you don't have to know the games coding or programming to make a program ala MK style. All you really need todo is get your memory card files to your PC.
For example, say I want to create a program like MKs for GT4, this is the process. Let's say I want to make an option to give yourself 'X' amount of credits.
I take my original GT4 savefile and plant it on my PC. Then, I go back and spend a bit of cash and modify my car in slot one - let's say I have a 350Z and I put racing intake on it. Then, I save it again. Now I go ahead and copy the new save onto my PC so that I have TWO GT4 save files on my PC.
This is where the work begins. I open up both of these files into a hex editing program and compare the values. There will be different values for the two save files, and the values that have been changed will exactly what I'm looking for
I'll find a few different values, but mainly I'll find out three things from these two files:
1) The money digit.
2) The "Intake/Exhaust Mod for car in slot 1" digit
3) The value for the 350Z Racing Intake/Exhaust.
From this information, I can code up a simple program that allows you to edit the amount of money you have, and what intake/exhaust is currently on car one.
Making these sort of program is actually very simple.
The hard, VERY hard part, is finding out ALL the modifier digits to accompany the cars. For example, there are over 500 cars in this game... Let's say we want to know EVERY digit for intake/exhaust mods. There are three different types of intake/exhaust availible... 3 x 500 = 1500.
That's over 1,500 values for intake/exhaust that need to be coded into the program to make it effective.
That is exactly what makes MKs such a GREAT program, is that just about everything you need to know is coded into the program, so you're not filling in random spaces with random numbers.
So, give me some time, and I'll get a program out that does what MKs did with GT3. If MK is making a program, that's even better, because I doubt I'll have the time and resources to make something as complete as MKs GT3 program, but, within a week or so, I will have released a hybriding program that is compatible with AR Max Drive save files.
(I just purchased my AR Max EVO w/ Flash Drive today, so give me a bit to figure out where I'm heading...)
