This is what I think about the conversion from de String Seed to the Number Seed.
As i discovered there is a formula to transform a string into numbers, although I dont know if this is 100% accurate.
The formula is just like the conversion from binary to decimal except it uses powers of 33 instead of 2. I dont know if Im making myself clear but instead of having, for example 2^4 its 33^4.
When converting from binary to decimal we have for example:
1 0 1 0 0 1 (bin)
5 4 3 2 1 0
as you can see we have 6 digits and we start counting from right to the left, numbering each digit, so the formula to this case will be:
(2^5 * 1) + (2^4 * 0) + (2^3 * 1) + (2^2 * 0) + (2^1 * 0) + (2^0 * 1) = 41 (dec)
The reason I just did that is to show the analogy between one formula and the other.
Now back to civ3, when we want to convert for example the string Civ, we must use the following table to convert each string to a number.
Now we start numbering the string:
C i v
2 1 0
C = 67
i = 105
v = 118
the formula will be (33^2 * 67) + (33^1 * 105) + (33^0 * 118) = 76546 (seed number).
One other thing, when we use only numbers as a string the seed number will be the same, example: 289450 = 289450 (seed number), on the other hand the string Civ3 witch is different from Civ(obviously), the char 3 now as a number associated to it (see the table above).
The result will be:
C i v 3
3 2 1 0
C = 67
i = 105
v = 118
3 = 51
the formula will be (33^3 * 67) + (33^2 * 105) + (33^1 * 118) + (33^0 * 51) = 2526069 (seed number).
After spending almost two hours trying to find the logic between this conversion I think I finally discover it. I started some games with the strings aa, ab, ac,ba.
I just hope this explanation hasnt been confusing, and forgive me about my poor english

Now back to civ3, when we want to convert for example the string Civ, we must use the following table to convert each string to a number.
------------------------------------------------------------------------------
String - Number | String - Number | String - Number
------------------------------------------------------------------------------
a - 97 || A - 65 | 0 - 48
b - 98 || B - 66 | 1 - 49
c - 99 || C - 67 | 2 - 50
d - 100 | D - 68 | 3 - 51
e - 101 | E - 69 | 4 - 52
f - 102 | F - 70 | 5 - 53
g - 103 | G - 71 | 6 - 54
h - 104 | H - 72 | 7 - 55
i - 105 | I - 73 | 8 - 56
j - 106 | J - 74 | 9 - 57
k - 107 | K - 75
l - 108 | L - 76 | ! - 33
m - 109 | M - 77
n - 110 | N - 78
o - 111 | O - 79
p - 112 | P - 80
k - 113 | K - 81
r - 114 | R - 82
s - 115 | S - 83
t - 116 | T - 84
u - 117 | U - 85
v - 118 | V - 86
w - 119 | W - 87
x - 120 | X - 88
y - 121 | Y - 89
z - 122 | Z - 90
-------------------------------------------------------------------------------
Note: I will soon update this with rest of the special chars.
Now we start numbering the string:
C i v
2 1 0
C = 67
i = 105
v = 118
the formula will be (33^2 * 67) + (33^1 * 105) + (33^0 * 118) = 76546 (seed number).
One other thing, when we use only numbers as a string the seed number will be the same, example: 289450 = 289450 (seed number), on the other hand the string Civ3 witch is different from Civ(obviously), the char 3 now as a number associated to it (see the table above).
The result will be:
C i v 3
3 2 1 0
C = 67
i = 105
v = 118
3 = 51
the formula will be (33^3 * 67) + (33^2 * 105) + (33^1 * 118) + (33^0 * 51) = 2526069 (seed number).
After spending almost two hours trying to find the logic between this conversion I think I finally discover it. I started some games with the strings aa, ab, ac,ba.
"aa" = 3298
"ab" = 3299
"ac" = 3300
"ad" = 3301
"ae" = 3302

"ba" = 3331
"bb" = 3332
