THUG2 on a Mac
Fan port
Tony Hawk's Underground 2 (2004) on the THUG1 port's engine: SDL2 and OpenGL, native builds, the original PC data you already own.
Start the tour
How Tony Hawk's Underground 2 (2004) got a native build for macOS, Windows and Linux: the engine of the THUG1 port, taught to run THUG2's own data, plus the settings menus, controls and saves a modern computer expects. Each guide is a short "how to", with the diffs that did it. The story section tells how it all happened, chapter by chapter.

The story
How THUG turned into THUG2, commit by commit
The map
Three layers, and almost every guide touches all three:
| Folder | What lives there | Touch it when |
|---|---|---|
Code/ | The engine and the game: skater physics, screen elements, scripting, the front end. Everything THUG2 does differently is marked THUG_THUG2; THUG2's own C functions are in Code/Sk/Scripting/thug2funcs.cpp. | A THUG2 script calls something the engine doesn't have, or the engine has to know about something new. |
Wn32/Code/Plat/ | The platform layer. Originally Xbox/Win32; here it's SDL2 + OpenGL + miniaudio: graphics, audio, input, files, saves. | Anything that talks to the computer: windows, keys, controllers, files. |
Scripts/patches/ | QScript patches parsed on top of THUG2's own scripts (the port's menus, the quick start). | You add or change a menu. |
The port doesn't edit THUG2's scripts, it patches them. See Scripts: it's the trick every menu here relies on.
How it got here

How to test a menu without touching it
The game is driven by a file. A small hook in Wn32/Code/Plat/Gfx/p_nx.cpp, active only when
THUG_DEBUG_DIR is set, reads one command at a time from $THUG_DEBUG_DIR/cmd: press a key, wait,
take a screenshot (the backbuffer, read right before the swap), jump to a level, save the game, quit.
Every screenshot on this site, and most of the bugs in the story, came through it.
THUG_LEVEL=TR goes straight to Training.THUG2's wheel turns when you press Up, and the skater spins it for you, every single time, like he's trying to win a fridge. Scripted tests made him spin it more times than any player ever will. He never won the fridge.
