NotAnyoneSpecial: wanted to add this func but it already exists so expanded.

{{Heavy construction}}

This is a table of functions in SimCity 2000 that have been at least partially reverse engineered and given names. It is probably going to be unpleasant to update, but at least it looks nice and you can sort it.

When adding new functions to the table, please make sure you insert them into the appropriate order by thunk address (the function that just has a <code>jmp '''ActualFunctionBody'''</code> instruction in it). If/when it gets too unwieldy we can split it out into multiple tables.

The Newspaper subsystem is mostly flavor text but provides general feedback for "City Issues", replacing "Survey" in Simcity Classic.

In the MacOS Simcity 2000 1.0 release a hidden nonfunctional debug menu of all the possible newspaper story types was left in the release copy. This was later completely removed in 1.2

NotAnyoneSpecial: +the newspapers have two different stories depending on this

'''Func Location:''' <code>0042E460</code>

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 ('''Array Location:'''<code>004E99E8</code>) and a random number between 0 and 19 of years from that base year. These values are stored in the array '''wCityInventionYears[17]''' ('''pointer:'''<code>0x4CB430</code>) 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.
<syntaxhighlight lang="cpp">
for (i=0;i<17;i++)
{
wCityInventionYears[i] = rand() % 20 + dataInventionBaseYears[i];
