Jonny Moseley Mad Trix is a heavily-rushed skiing game which attempts to rip off the gameplay and design of SSX and SSX Tricky. It suffers from bland gameplay, but has a memorable soundtrack.

Although unconfirmed, it seems EA stole some ideas from this game for SSX 3 in retaliation, notable examples being the characters Big Mountain and Skier X.

Dragon Rage Source Code

Download PAD0.PAD File: JonnyMoselyMadTrix PAD0.ZIP (16.33 MB) (info)

The files PAD0.PAD and PAD1.PAD on the North American disc are renamed .ZIP archives containing partial pre-release source code and a few development tools for Dragon Rage, another title from 3DO Company, still using its pre-release name Dragon Wars of Might and Magic. The only difference between PAD0 and PAD1 is that PAD0 is slightly corrupted and two files can't be extracted from it.

In the European releases, both files are replaced with PAD0 and PAD1, without extension, which are copies of MOVIES/WIPEOUT1.PSS.

Unused Character "Locked" Mode

When a character hasn't been unlocked yet, they're simply not in the Ski Shop, and therefore both unviewable and unselectable. However, all characters have an unused "locked" mode where they appear in the Ski Shop, but with no description, their name being displayed in black instead of yellow, and are unselectable. This mode is used elsewhere, as the "Big Mountain" mode is initially locked using it, but characters never use this. This can be activated by freezing 0x1F44740 to a value of 0x000000FF and saving your game.

Debugging Functions

Inside the executable is the remnants of a complex set of debug menus. The functions that call these menus, as well as the menus themselves, were removed. The lists of options and the options themselves were not, making it possible to somewhat accurately restore these menus. The following codes can be used in conjunction with the PCSX2 emulator to change the pause menu to display the various debug menus. Note that the Physics Menu is incredibly hard to read due to the proper font and line spacing not being present.

The PNACH below is for the US version of the game:

Skier X Oddities

Unlock Sequence

Skier X is the game's 100% completion bonus, complete with a special unlock sequence. Upon completing a course with the requirements for his unlock, the game plays every bonus movie in a row, then takes you back to the character select screen where he becomes available to play as. However, due to an unknown error in the game's programming, the conditions for the character's unlock cannot be met, leaving this sequence unused.

The code for this sequence with unnamed functions given proper names:

 if (DAT_003988e0 != 0) {
   if (skier_x_unlocked? == 0) {
     FUN_0011c268(0x2e5a40,local_30);
     FUN_001a3de8(local_30[0]);
     sprintf?(acStack160,"/movies/%s");
     FUN_001da9c8(acStack160,0,1);
   }
   else {
     FUN_001da9c8("/movies/ERTrick1.pss",0,1);
     FUN_001da9c8("/movies/Mostrick.pss",0,1);
     FUN_001da9c8("/movies/Wipeout2.pss",0,1);
     FUN_001da9c8("/movies/Tricks1.pss",0,1);
     FUN_001da9c8("/movies/Wipeout4.pss",0,1);
     FUN_001da9c8("/movies/Tricks2.pss",0,1);
     FUN_001da9c8("/movies/wipeout1.pss",0,1);
     FUN_001da9c8("/movies/Tricks6.pss",0,1);
     FUN_001da9c8("/movies/Wipeout8.pss",0,1);
     FUN_001da9c8("/movies/VDTrick1.pss",0,1);
   }
 }

Hidden "Stats" Mechanic

When Skier X is unlocked the dev-intended way (which isn't possible) he already has max stats, and doesn't have any upgraded gear to unlock. Despite this, he does have a hidden "stats" mechanic that's not possible to see without hacks. If Skier X is unlocked before anything in the game has been completed, he'll have the starting stats of Jonny, but every new course that unlocks adds to his stats. The courses don't have to be beaten or have a medal won on them, they just have to be unlocked. The stats display in the menu doesn't reflect this change. Upon unlocking the final course, his stats raise to what they're supposed to be. This could indicate he was supposed to be unlocked at an earlier point in time, or that stats could originally be upgraded in ways other than unlocking new gear.

Regional Differences

A few of the releases have minor differences that affect gameplay in small ways.

Europe 1.00

• Game camera has a slightly higher field of view at all times.
• The position of the 3D medal during Slopestyle events is incorrect.
• All speed-related values were increased, making traversing the courses much faster.
• A misplaced 2x Multiplier in the San Francisco course had its position slightly corrected.

France/Germany 1.00

• The position of the 3D medal during Slopestyle events was fixed.

Italy/Spain 1.00

• Same as previous release.

North America 1.01

• Released before all other releases despite having a later revision number.
• A 2x multiplier in the San Francisco course was misplaced, making it too low to collect.
• Speed values and field of view are at the intended levels.
