Hex Editing Madden

[boricua1111]

found this: I don't nkow the structure of the madden rosters but I found it on an ea sports forum (not EA's site though)

unsigned int CalcMC02(char *buff, unsigned int length)
{

unsigned int position = 4;
// Declare our registers. Some are used, some aren't. I tried keeping as close to the
// actual assembly **** as possible
DWORD r3, r4 = length, r6, r7, r8, r9, r10 = r4 - 4, r11;
// First step
DWORD first = _rotr(buff[0], 8) | _rotr(buff[1], 16);
r7 = _rotl(buff[2], 8);
first |= r7;
r11 = buff[3];
r11 |= first;
r11 = ~r11;

for (position = 4; position < length; position++)
{
// mask (22, 29), (working from left to right) bits 22-29 are set to 1.
r7 = _rotl(r11, 10) & 0x3FC;// >> 0x14;
// Shift r11
r11 <<= 8;
// Combine
r11 |= (unsigned char)buff[position];
// Grab the value from the crc table
r7 = CRCTable[r7 >> 2];
// **** with r11
r11 ^= r7;
}
return r3 = ~r11;
}

someone also made a checksum dll

Is it possible to hex/change the site/stadium of the superbowl to another place?

Would be cool to change it to Miami, Dallas, San Diego... etc

Thanks a ton! Unfortunately, feudalnate pointed out that EA started changing up their crc table ( ie. their polynomial ). Many say reversing out the poly is impossible, though I have found a couple of pages that are promising. All that said, unless we can find that poly / table, we're stuck.

Just to kind of 'whet your whistle', here is what my editor looks like - REMEMBER - until we can figure out the checksum thing, this is nothing but a VIEWER!

( OK images not showing in my post... so here are links to them instead! )
Main
Contracts
Appearance


Simplistic, yes, but as you can see, all of the player data is there ( lots of scrolling to the side for other fields ).

Impressive, it has been long overdue for this kind of software for madden. Madden could get lots of roster love with this tool. Brilliant stuff man, keep it up please. Thanks

Looks great. What's the old polynomial?
