Random Numbers
From ASSS Wiki
SubSpace uses random numbers primarily in its encryption, generating prizes, and controlling doors.
The following code is used in generating the encrypted keystream, prizes, and doors:
DWORD SS_RNG(DWORD seed)
{
DWORD nseed, temp;
temp = (MULT_C * (unsigned __int64)seed) >> 32;
temp = (temp >> 16) + (temp >> 31); //aka the sign bit
nseed = (seed % DIV_C) * 16807;
nseed -= (temp * 2836);
nseed += 123;
if (!nseed || nseed > 0x7FFFFFFF)
nseed += 0x7FFFFFFF;
return nseed;
}
