Tony Hawk's Underground (Aug 15, 2003 prototype)

A preview build of Tony Hawk's Underground for the Sony PlayStation 2, dated roughly a month and a half (48 days) before the final build.
==Notes==
===Demo Mode===
A demo mode flag is set to on, limiting some of the game's functionalities. Through either modding (e.g. using the instructions below) or using the xdelta patch provided in the download link, said flag can be turned off and the full game unlocked. This also activates several debug menus in both the in-game options, Create-A-Skater and enables an option to access the level select in Story mode before entering it.
*Only the first three levels (New Jersey, Manhattan and Tampa) are selectable. When unlocked, aside from these three as well as Moscow and the test level, all others crash the game upon loading. The crash seems to happen at the point pedestrians are loaded, as the game loads these levels fine without them. Certain goals in Moscow that use ped models that exclusively appear in these missions, will crash the game as well.
*In Story Mode you can only progress until Chapter 10. After beating the Tampa AM goal, the words "DEMO BUILD" flash on the screen a few times and you are unable to continue the story.
To unlock the game, open the disc image in a hex editor and set the value located at 0x14F6420E to 00. Then edit the two references to startup.qb at 0x000DE9D2 and at 0x2DE3E4E7 to something else. Note that both replaced references still have to be consistent!
To unlock some of the additional levels like "West Side" and the test level, set the values at addresses 0x2DF1D592 and 0x2DF1D5A3 both to 01.
===General Differences===
*Has an additional executable file on the disc, dated July 30, 2003. It can be used by simply routing to this file in SYSTEM.CNF.
*There are no FMV's in this build. This means that the gameplay demos that would play in the main menu after a few moments of inactivity don't play as well.
*"Download your face" in the main menu is called "Create your face".
*Hotter Than Hell is in an unfinished state with varying degrees of graphical glitches, untextured spots (notably the tunnel below the stage), some missing rail flags and placeholder banners.
*There are a few levels in the game files, that were removed from the final game. Notably, a level called "West Side" which is assumed to be a test level for Neversoft's later title Gun (2005) and an early scrapped level called "Australia".
**A few others, aside from the test level and a broken version of London (a THPS4 leftover), are unfinished ports of levels featured in the first two Tony Hawk's Pro Skater games, e.g. School I, Downhill Jam and Philadelphia. Those would return in fully functioning form in Tony Hawk's Underground 2 (2004).
*Each skater in the character select screen starts off in a T-pose.
*Several of the game's hidden characters have not yet been implemented and instead show an unclothed, bald version of the standard CAS model.
*T.H.U.D is simply called "Creature".
*A lot of voice clips are missing and sometimes the player would switch male and female voices.
*A few Park Editor pieces are found in different categories but appear to be mostly unchanged.
*The option to load pre-made parks is inaccessible.
*The "View Goals" menu hosts a few differences from the final game.
**Selecting certain goals changes the background image to various spots in the level you're currently in, whereas in the final, it's always the same picture.
**The last challenge of each chapter has a green star reading "Final" next to it.
**Other differences include either misspellings, grammatical errors, some changes for legal reasons (e.g. mentions of trademarks) and reduction of uncensored profanity to receive a T rating before release.
===Soundtrack Differences===
*Some of the songs in this build appear in less censored form. Notably, "Underground Up" by Mr. Complex, which is featured in this game with a unique and unreleased version.
*A few tracks would also be edited down for the final. Frog One's "Blah Blah" has a unique introduction with some radio channel surfing, which would not appear in any commercial release.
*"Suffer Some" by Jane's Addiction, as well as "War Games" by Living Legends are absent from this build.
*Instead there is a track called "Can You Find" by Freestyle Fellowship, that did not make it to the final game.
===Cheat Codes===
This build uses the same cheat code inputs as Tony Hawk's Pro Skater 4 (2002). To be able to enter these codes, navigate to the main menu after unlocking the build from it's demo mode, then go to "Options" and "Cheat codes". The sound of a cash register, a THPS4 leftover which would be replaced for the final version, confirms a successful entry.
