Previously Undocumented Cheat Codes

The only previously documented cheat codes for the game are tightrope, which unlocks the 'Perfect Rail' cheat, and birdman which unlocks THPS1 Tony Hawk as a playable character. However, there are numerous other cheat codes defined within the game's scripts. These cheat code definitions are not defined in plaintext, but instead stored as hashed values using a custom hashing algorithm based in part on iteratively hashing the cheat code using CRC32 100,000 times. Because of this, the cheat codes cannot be trivially determined or decoded. However, through bruteforcing numerous possible cheats, a number of previously undocumented cheat codes have been discovered.

Development Unit Switch Debug Display

There are a number of General Purpose Input (GPI) dip switches within the hardware development kits used by developers to test, debug, and develop PSP games. The status of each dip switch is checked by calling a kernel function, sceKernelGetGPI(). While these dip switches do not exist within retail PSP units, by modifying the return value of sceKernelGetGPI() to non-zero values, one can pretend that certain dip switches are enabled. The retail version of Tony Hawk's Underground 2: Remix retains calls to this function within its code, and when pretending certain dipswitches are enabled, various debug information is displayed on-screen. Depending on the switches enabled, this can include a bar displaying Graphics and CPU loads, an FPS display, and a breakdown of the specific features that are contributing to those loads.

Only Graphics & CPU Load Bar Enabled (See Top Left Corner)

All Displays Enabled

With all displays enabled, some of the fields displayed include:

Debug Options

Code for a debug menu is present within the game's scripts. While not usually accessible to the player, the only check in place to determine whether or not to show the debug menu is a check of a flag in memory indicating whether or not the game is running off of a UMD (for ULUS10014, this flag is at 0x08a651d4). By setting this flag to false before opening the pause menu in game, a new 'Debug Options' entry appears, similar to the original version of the game.
