Inventions
Location:0042E460
In Simcity 2000 during game set up the invention date of each technological development is randomly generated and set in NewGameSetup. These dates are a combination of a Base Year for the invention of that technology sourced from an array (Location:004E99E8) and a random number between 0 and 19 of years from that base year. These values are stored in the array wCityInventionYears[17] (Location:0x4CB430) in the same order as the base array. If the randomly determined year is before the founding year of the current game then it's automatically unlocked, otherwise the game will check monthly if it has reached the specified year.
"Highways" appears twice because, I suspect, the list text-strings will "loop" back to the first "Innovation" type invention that appears. Possibly some sort of bug because something was removed.
for (i=0;i<17;i++)
{
wCityInventionYears[i] = rand() % 20 + dataInventionBaseYears[i];
