The THPS Hacking Site

UPDATE: I have written the freeware Win32 console program STRINGCODE for the conversion of this data to usable codes. Full documentation is provided every time the program is run, but here's a basic rundown:

If you have an Xplorer, start the program and type X followed by a return. If you have any other cheat cartridge, start the program and type G or S followed by a return. Then simply type in your desired address and text; let's say you want to change "CROOKED GRIND" to "JUMPING BONER". You would look up the offset here, under grind tricks, and find 9FC1C. Then you would check your string against the existing one, and make sure it fits into the space provided by the existing string and the number of spaces after it. In this case, they're the same length, so we're fine. So we just type:

9FC1C "JUMPING BONER"

Then we hit enter. Whatever codes it spits back can be input to your cartridge however you like, and if you then enable the codes and go do a crooked grind it will say "JUMPING BONER" instead.

This should allow more people to use this information. MAKE SURE you know WHICH version of the game you have -- NTSC or PAL. The offsets are NOT interchangeable, and while I am reasonably sure interchanging them will not *hurt* anything, it won't work the way you expect.

I would like to be particularly hedgy about the different phrasings of "rail to rail" in the following list; I haven't had time to verify that I've got all the right levels matched with the appropriate rail to rail transfer phrasing. If you find one to be in error, please let me know. I may also have the fountain gaps mixed up.

At offset A7250, you can find what looks like the trick structure. Each trick contains several parameters, which are detailed here. Basic layout of trick record vaguely explained:

Offset             Location in memory            Last + 2C (44)
Combo              Skater and button combo       Offset + 00 (2)
Flags              Flags for trick behavior      Offset + 02 (0)
Trick              Animation to play             Offset + 04 (4)
Speed              Speed at which to play        Offset + 08 (8)
Name               Offset of name in memory      Offset + 0C (12)
Hold               Frame at which to hold trick  Offset + 10 (16)
Slack              Landing slack in frames       Offset + 14 (20)
Grind              Grinding slack in frames      Offset + 18 (24)
Points             Default points for trick      Offset + 1C (28)
# Flips            Number of backflips to do     Offset + 20 (32)
F.Speed            Speed of backflips            Offset + 24 (36)
Zero               Always zero                   Offset + 28 (40)
Text Name          Reference for hackers         See NAME

You will notice that everyone's specials are the same animations: 3E, 3F, and 40. This means that no matter how you try to get Geoff Rowley to do a Heelflip to Bluntslide, he will never do one -- his animations *always* look like a backflip, double hardflip, and darkslide, no matter what the screen says.

Changing name offsets (or any 4-byte number, for that matter) is awkward, because it needs to be done BACKWARDS. It looks like changing 800D1908 to 8009FC98 in the NTSC varial trick record would be done with 800A725C 8009 and 800A725E FC98, but this is WRONG. It needs to be done with 800A725C FC98 and 800A725E 8009. WHY you have to do it this way is a hard thing to explain, so just take my word for it on this one, okay? ;)

At this time, there is NO WAY to make trick animations play repeatedly. You can't make a regular heelflip into a double heelflip. You can't turn a triple kickflip into a six-time kickflip. It doesn't work that way. You also can't stick tricks together to make things like a double hardflip 540 McTwist. There OUGHT to be a way to add *spins* to the tricks, but I haven't found one yet.

While there is no way to combine tricks arbitrarily, there is *some* good news: ANY trick can have backflips added to it... just set the "# Flips" and "F.Speed" to something more than 0. For one flip, a speed of 0080 is good. For two, a speed of 00F0 is good. Frontflips use negative numbers for speed, which is complicated: suffice to say that FF7F is a good speed for one, and FF00 is a good speed for two. Remember to add your numbers together in HEX, not decimal: Offset + 20 for number of flips, Offset + 24 for speed. If you are creating a frontflip, you also need to set Offset + 26 to FFFF (because of the way computers represent negative numbers). All numbers provided in this paragraph are HEX numbers: 20 means thirty-two, not twenty. Use the Windows calculator in Scientific view if you have trouble with doing arithmetic in hex (most people do, and it's always good to double check anyway).

NOTE: Private Carrera's specials are copied up into the area where Officer Dick's specials are after entering the "super code". This gets pretty complicated if you use the Game Shark version of Private Carrera. ;)

COMBO INFORMATION: Every special move has a skater ID and button combo. I think the way this ends up working is that whenever you press a button combo, it looks for the skater ID you're using in the table, then matches your combo to a trick -- no match, no trick.

You can change the button combos however you like, and even improve the gameplay this way. Special grinds are much easier to land repeatedly if they don't use the left and right buttons, for example.

In order for a trick to be a grind, it has to use the grind button. You can't give someone a grind on the flip or grab buttons, unless you want it to be an air trick.

FLAG INFORMATION: what all the flags mean... there are four hex digits in each flag set. The first digit is always 0, and the rest mean various things. The digits labeled "FLAG 1" and "FLAG 2" can be added up together, so "handplant and no tweak" for flag 1 would be 4 + 2 = 6. You can probably also add up button combos -- Up + left at the same time would be 1 + 4 = 5. I wouldn't do this, myself.

ALWAYS 0

FLAG 1 (0-7)
Flip After         1    Flip skater 180 degrees after trick.
Handplant          2    Handplant, not grind.
No Tweak           4    Not sure exactly what this means in game terms. 

FLAG 2 (0-F)
No spin            1	Don't let the player spin.
No spin score      2    Don't count spins for points.
Rotate After       4    Rotate skater 180 degrees after trick.
Not Grab           8    I think this has to do with holding tricks.

ALWAYS 0

So let's say you don't like not being able to spin and tweak backflips. Looking at the above information, you note that all you have to do is subtract 4 from flag 1 and 1 from flag 2. So you look up Geoff Rowley's backflip, and you see that the flags for it are 0410. This is easy enough, you just need to zero it out; so you look at the offset -- A7B98 NTSC, A7CF4 PAL -- and then check the offset table for the record up top to see that Flags are offset + 02. Adding 2 to the above offsets, we figure out that what we need is to put a 0000 in locations A7B9A (NTSC) or A7CF6 (PAL). Since we're modifying two bytes, we use an 80 code, and we get:

Geoff Rowley can spin backflips (NTSC):	800A7B9A 0000
Geoff Rowley can spin backflips (PAL):	800A7CF6 0000

The same process will work for pretty much any character's special moves. You can do some weird things, too; if you clear the "Handplant" flag from the Burntwist, it becomes a really strange looking grind.

Here's the best I can figure on the data dumps; we have the name of the level, location of the level, name of the map, two 0 fields, a trigger filename, the gold/silver/bronze medal required scores, the image to show when selecting the level, two who-knows-what fields, the background to use when loading the level, the background during play, what you have to hit five of for a tape, number of tapes necessary to get to this level, number of medals necessary to get to this level, high score, pro score, and then a bunch of stuff I haven't figured out yet.
