CM 01/02 function map

A map of every function in cm0102.exe 3.9.68, the last official patch of Championship Manager 01/02. Each of the 6,863 game and library functions has its address, the source file it came from, a name, its calling convention and one sentence on what it does.

The data map covers the 4,428 global variables that these functions touch. Each global has its address, size, type, a name, one sentence on what it holds, and the functions that read and write it.

Search both by address (the offset that Olly shows) or by word: https://maxevans60.github.io/cm0102-function-map/

The map came out of the Bosman Edition, a recompiled port of the game to Mac, Windows and Linux. It is free for anyone who patches, mods or studies the game.

Look up an offset or address

The map uses the addresses that OllyDbg and x64dbg show, written as 0x8e7810. Olly shows the same address as 008E7810. On the champman0102 forum these are called offsets.

• Some offsets in patch lists are positions in the exe file. Add 0x400000 to one, or tick "File offset" on the search page.
• Most patch offsets lie inside a function. The search page shows the function that holds the address.
• An address in the data section, such as 0xae2c90, gives the global at that address, or the global that holds it.
• The search also takes a word, such as loan, prize, League:: or g_current_date.
• Each result links on. A function lists the globals it uses, and a global lists the functions that read and write it.

Files

File	What it holds
map/index.md	Every source file with its number of functions
map/<file>.cpp.md	One page for each source file: address, size, name, convention, purpose, confidence
map/functions.tsv	All named functions with every column, for scripts and spreadsheets
map/names.tsv	Address, file, name, confidence, model and the research docs that cite it
map/not-high.tsv	Every row that is not high, with one line on what is missing for high
map/function-files.tsv	All 11,747 function starts, unwind funclets and runtime code included, with their file
data-map/index.md	Every owner file with its number of globals
data-map/<file>.cpp.md	The globals of one owner file: address, size, type, name, description, evidence, confidence, writers, readers
data-map/shared.md	The 463 globals that four or more files use with no main owner, such as the current date and the read-only constants
data-map/globals.tsv	All 4,428 globals with address, size, type, name, readers, writers and confidence
data-map/data.tsv	All globals with their owner file and description, for the search page and for scripts

The source file names come from the assert strings in the exe, such as E:\dev\CM3\cm3 00-01\cm3\code\comp\leagues\league.cpp. A function without an assert of its own gets the file of the code around it. A competition class keeps the method names of its base class for each vtable slot, so SweCup::update_staff_records_for_status is slot 17 of the cup vtable.

How the map was made

AI agents (Claude Opus, and Sonnet for 254 library functions) read each function. They read its strings, asserts, callers, callees, vtable slots and decompiled code, and gave it a name. Then fresh agents reviewed every name with medium or low confidence, every shared stub and every false entry. A third agent settled each disagreement. The review changed 842 names. A confidence pass then gave the agents the names of the globals and of the reviewed neighbours, and checked the medium and low rows again. It raised 245 rows to high and changed 10 names.

Each row has a confidence:

• high (5,702): the evidence quotes a string, a caller or a vtable slot that pins the purpose.
• medium (1,133): the shape of the code and the callers agree, but no single fact proves the name.
• low (28): a guess.

Read the code before you build a patch on a medium or low name. A name helps you find code. It does not prove what the code does.

The data map lists each global on the page of its owner file: the file of most of the functions that use it. A script named 3,015 globals from facts in the exe: the key ids, the read-only constants by value, the vtables by their constructor, and the string pointers. Agents (Claude Sonnet, and Opus for one) named the other 1,413 from the functions that read and write them, then a confidence pass checked them again. The description of a field of an object reads g_<object>+0x<offset> <field>. Of the 4,428 globals, 3,808 are high, 574 medium and 46 low.

Every name comes from reading the exe's own code. While they worked, the agents also had the Offset Index thread on the champman0102 forum to hand as a check. Where the thread names a global or a field, they compared it with the code before they used it. Rows that rest on it say "forum offset index" in their evidence. Thanks to everyone who added to that thread.

What the map holds

The map holds names, file names and short descriptions. It holds no code, decompiled code or data of the original game. To read the code you need your own copy of the game. Eidos made it free in 2008.

Report a wrong name

Open an issue with the address, the name you think is right and what the code does. A caller, a string or a field offset helps most. The map is generated from the Bosman Edition repo, so a pull request that edits map/ or data-map/ would be overwritten. The fix goes into the next update of the map.
