General THPS(X) / Re: THAW CAS Flash Glitching Deep Dive
« Last post by Challenger on September 01, 2025, 12:04:51 pm »Final update for now. For reasons unknown, the glitch doesn't work with facial hair color and board wheel color using the hex editor method. I also tried to document a table for which parameters go with which objects but the game engine constantly adds and removes parameters from the array in the save file as you make various changes.
And speaking of skin, I present these abominations! All I can say is the guy looks like he has LSD Freddy Krueger hands and the girl looks like a witch fit to be burned at the stake.
Also tried flashing a few glasses. The Aviators look like a monocole off to the side and in some cases the frame just disappears, leaving floating lenses that look pretty cool. Glasses that colorize the lenses look even more broken (last screenshot).
The Afro turned out well, but he looks like he's literally beside himself. He also gets a wind sail behind him at times.
Now testing the goofy hats. The Dunce Hat is another one that completely vanishes. Don't look down or else you skater will stare back into your soul.
And there are certain hats that flash particularly well with no blinding spiky polygon side effects. Here are the Headphones. They are perfect except for the invisible piece in the center.
Here's the Pirate Hat as another example.
And the Sombrero. I believe this was commonly used in THUG2 because it looks so perfect when flashed.
Some more imperfect hats. The Sun Hat...
The Top Hat...
And the Tall Hat, which looks like a party hat to me...
Here's the Turban, definitely not perfect.
And the best, in my opinion, has to be the Paper Bag. It looks like Spongebob soaked up some rainbow paint. The geometry isn't even broken, just off-center. The eyeballs also flash, and the bag warps and flops all over the place while you run. This one's great fun!

If you bothered to scroll this far, I've attached the male and female flashy skin CAS files if interested for SLUS-21208 version 1.00. You have to have memory cards configured in PCSX2 to use a folder, not a memory card image file. Just unzip the file and paste the 2 folders into the PCSX2 memcards\memorycard.ps2 folder in wherever you have that data stored and they will show up in-game so you can load and experiment with them. I've found swapping around clothes changes their appearance, to make things extra creepy.
Thanks for reading, now go outside and enjoy your Labor Day.

General THPS(X) / Re: The State of CAS Flash Glitching in THAW
« Last post by Challenger on August 31, 2025, 06:44:15 pm »I hope my consecutive posting isn't an issue, there's too much to add to a single post and breaking these up hopefully makes things more digestible.
I went back to the hex editor and found the reason some items don't flash when have I hue set to the far left (red), saturation 17 ticks to the right, and value 18 ticks to the right. Some items don't end up with the correct pair of values to trigger the glitch. Injecting 0x65 for sat and 0x56 for val lets you flash literally anything. Just re-calculate the CRC32 checksum and inject the new checksum into the first 4 bytes of the CAS file.
The CAS parameters are almost halfway into the file at the top of the next block of data after a block of zeroes. I call this the LUSA zone (Sonic Reducer certainly ain't one).
A link for that checksum tool if anyone wants it (I think I got this from thmods.com before it died a few years ago):
https://archive.org/details/thug2-save-file-checksum-utility
A shirt (tanktop) that normally doesn't flash using the in-game adjustments:
For the hue, it's a bit weird. Here's how I found it. 2 bytes back from 0x65 0x90 0x21 0x56, there should be 0x1F before 0x90 0x20. Before that should be a 0x92. So the sequence should appear as follows to edit the hue/sat/val and flash an object on your CAS:
What I've marked up in red is what I noticed after moving the hue 1 tick to the right from the far left (red) position (hue in the far left position is needed for the glitch to work). The 0x92 at the beginning changed to 0x90 and 0x05 was inserted after the following 0x1F. Can't explain why, maybe it's a least significant byte that otherwise isn't needed. I deleted that 0x05 and changed the 0x90 to 0x92. Then the object was flashed since that set the hue to the correct far left (red) position.
Confused yet?

General THPS(X) / THAW CAS Flash Glitching Deep Dive
« Last post by Challenger on August 31, 2025, 11:07:46 am »Background:
https://thpsx.com/forums/index.php?topic=288.0
I recommend reading that whole thread but TLDR, yesterday I confirmed the CAS color flashing glitch works in THAW (as well as THUG2 as many people already knew). Now that I have found the CAS clothing/accessory infinite saturation and value Gameshark codes for the colors...
Inf. Saturation Scales:
20D0CD54 00000000
20D0CD68 00000000
Inf. Value Scales:
20D0CD7C 00000000
20D0CD90 00000000
I began testing pieces in THAW in PCSX2 to see which clothing and accessory items flashed well. Unfortunately the color effects do not apply consistently across all items (I think this was the case in THUG2 as well) so the glitch doesn't work with everything. Also, secondary colors do work as well but the main color has to be flashed first.
Here is a list of what works with this glitch (items further down each list seem to not work).
Torso Options
Sleeveless
Ringer T
Long Sleeve T
Long Striped
Baseball 1
Baseball 2
Layered T
Military Coat
Hoody
Zip-Up Hoody
Pully Hoody
Zip Sweater
Leather Vest
Leather Jacket 1
Leather Jacket 2
Denim Jacket
Sleeveless Denim
All Left Accessories
All Right Accessories
Glove 2
All Misc Items
All Backpacks
Here's a list of what doesn't work. Since the selection of pants is much more limited and only a small number don't flash.
Leg Options
Camo Shorts
Hurley Icon Jeans
DVS Jeans
Etnies Jeans
DC Aidan DX Jean
Here is a list of what works:
Knee Pads
All Socks
All Shoes

Devil Lock
McSqueeb R

Liberty Spikes 2
Spiked 2

Hats
Baseball Cap
Cap Backwards
Upturned Bill
Trucker Backwards
Beanie
Brimmed Beanie
Beret Cap
Hat Hair Medium
Unfortunately glasses, facial hair, skin (yes, really) and board wheels are not flashable in-game.

Questions & Tutorials / Re: THUG2 CAS Flash Glitch Discussion
« Last post by Challenger on August 30, 2025, 11:54:23 pm »Pretty sure nobody is reading this thread at this point, but a very interesting development I made tonight:
I saw PCSX2 got some major updates recently, and decided I would pick up this "cold case" and blow off the dust. What I concluded nearly 6 years ago is incorrect. The false premise that lead me to this conclusion is I thought Neversoft clamped the maximum saturation and value variables for the colors when saving and loading a skater file in THAW. If I inject hex values 0x65 and 0x56 for saturation and value for any skater clothing or accessory, I'm actually not sure why the flash glitch didn't work in THAW. I'm guessing I was just editing the wrong object parameters. Neversoft either didn't know about the glitch, knew about it and didn't patch it out, or simply couldn't due to time constraints before release. It's also likely they were aware of it but couldn't find the underlying cause.
This was right under my nose and I just didn't find the correct thread. A bunch of Gameshark codes for THAW were actually here, including the crucial CAS infinite saturation and value codes:
http://www.thps-mods.com/forum/viewtopic.php?t=2936
Of course, that site is down now. By some miracle, Brave Search still showed that thread in a search result. It's frustrating how difficult it is to preserve this kind of information in 2025. Anyway, someone was kind enough to archive this thread in the Wayback Machine. One single copy from 2022:
https://web.archive.org/web/20220924080012/http://www.thps-mods.com/forum/viewtopic.php?t=2936
The THAW codes for what I was looking for:
Inf. Saturation Scales:
20D0CD54 00000000
20D0CD68 00000000
Inf. Value Scales:
20D0CD7C 00000000
20D0CD90 00000000
Ladies and gentlemen, it is possible. CAS flash works in THAW, and the glitch is persistent across CAS save files. More to come in a new thread with lots of screenshots:
https://thpsx.com/forums/index.php?topic=1752.msg9247
I modified a THAW CAS and loaded it in the game. Unfortunately Neversoft has clamped the values to a maximum of 0x5A and 0x4B. I verified this by changing the values, updating the checksum, importing the save file, loading THAW, saving the file in THAW, and re-exporting it again to view in a hex editor. So in short, Neversoft took note of this in THUG2 and didn't want a bunch of flashy messes when people were playing online in THAW.

It's also likely they were aware of it but couldn't find the underlying cause.
That doesn't mean the effect itself isn't achievable, if someone would be so kind as to write an infinite colors Gameshark code for THAW I would be able to say for sure if it's possible at all or not.

General THPS(X) / Re: [THPS3] PARTYMOD
« Last post by TuF on March 15, 2025, 10:28:32 am »I recently found out about your party mods through Reddit and I'm pretty hyped since THPS3 and 4 didn't allow me to set the controls exactly like they were on PS2 (buttons couldn't be mapped twice for example like for reverts and spine transfers). I wanted to replay those last year on my laptop on my breaks at work but this was a major turn-off. So within a discussion on Reddit about this he would let me know.
By reading the GitHub description, it says the mod is made for the English version. Not that I have any problems with English but I'm totally nostalgia driven and I wanted to replay both games in German (THPS3 even had a German dub). I guess it will fail installing it over the German versions so my question is: Is there any chance this will work after maybe swapping out audio files and those containing text after patching? Or will there be a patch for different versions someday maybe? Anyway, thank you so much for these major improvement mods.
Best,
TuF

General THPS(X) / Tony Hawk's Underground GBA Patch
« Last post by RainbowDash321 on January 24, 2025, 01:35:57 pm »I pretty much finished working on this patch. I did started look into this game back in late 2010s but I gave up. Thankfully I still kept the address and values text document I wrote years ago. I had planned trying to figure it out fixing this rom at the time.
Tony Hawk's Underground was released on GBA by Vicarious Visions and the most noticeable is that it's impossible to 100% legitimately due to broken codes by developers. This issue was never fixed in Tony Hawk's Underground / Kelly Slater's Pro Surfer double pack either. This patch aims to fix those problems so you can actually 100% this game. Unlike any other Tony Hawk GBA games, I removed the heath bar and area text names completely in Story Mode.
Oxygen Bar? gap: This gap is placed but for some reason it won't register because of Who Needs Oxygen? byte codes are affecting it. Now it works flawlessly.
Who Needs Oxygen? gap: This gap placement had problems. I adjust the coordinates and works fine.
South Lip gap: This gap is placed but wouldn't register because there's a byte code missing to activate it. I added the byte code back in the rom and works flawlessly. Hangar gaps check list order is fixed.
Buying Style gap: This gap does exist but the byte codes are messed up. I did got it work but only use the left ramp.
Puerto Uno gap: This gap does exist but the gap coordinates are off. I did adjust the gap coordinates and works flawlessly.
