Calculate any version

[[RCZ]ShadowKing]

Hello,i'll tell you in this thread how to convert client->server or server->client versions for any version(even for the "wrong" version 9.99.99).
This is the original formula decompiled from main.exe so it will work 100%.

I will calculate the 9.99.99 client version highlighting the numbers i used from original string:

48+9+1 = 58(3A in hex)
48+9+2 = 59(3B in hex)
48+9+3 = 60(3C in hex)
48+9+4 = 61(3D in hex)
49+9+5 = 62(3E in hex)

NOTE: the purple bold,italic,underlined numbers represent the place of version number in the client string(1 for first 9,2 for second 9 and so on up to 5).

now convert from decimal to hex using scientific calculator provided by windows(58->3A,59->3B and so on) and put all values together and you will get "3A3B3C3D3E".Now get this hex string and use this page to convert it from hex to string and voilla : ":;<=>".

NOTE: to avoid the conversion from hex to string you simply can replace the bytes from main instead of replacing ascii strings.

client->server conversion ":;<=>" = "3A3B3C3D3E" (in hex using this page)

3A represent 58
3B represent 59
3C represent 60
3D represent 61
3E represent 62
(hex to decimal with windows calculator)

58-48-1 = 9
59-48-2 = 9
60-48-3 = 9
61-48-4 = 9
62-48-5 = 9

now just put a point starting from right to left after each group of 2 numbers.

"9.99.99"

I hope you will find this useful.

Automate it...

<?php
function h2a($str)
{
    $x = '';
    for ($i=0; $i < strlen($str); $i=$i+2)
    {
        $x .= chr(hexdec(substr($str, $i, 2)));
    }
    return $x;
}


$mver = '9.99.99'; // server version


$mver_split = addcslashes("$mver",'0..9.');
$n = explode("\\", $mver_split);
$base = 30; // hex value (48 dec)
$h = dechex(hexdec($base)+hexdec($n[1])+hexdec(1));
$h .= dechex(hexdec($base)+hexdec($n[3])+hexdec(2));
$h .= dechex(hexdec($base)+hexdec($n[4])+hexdec(3));
$h .= dechex(hexdec($base)+hexdec($n[6])+hexdec(4));
$h .= dechex(hexdec($base)+hexdec($n[7])+hexdec(5));
$mumv = h2a($h);


echo "Hex: [".$h."] - Ascii: [".$mumv."]";
?>

Yow, it's been years! Thanks for this very useful snippet! I have decided to make it more useful for public viewers. Credits all to you. Cheers!
