Darkaiser | Crash Team Racing - Nitros Oxide on Roster (Mod Release v1.0) @Darkaiser | Uploaded March 2022 | Updated October 2024, 4 hours ago.
The most-awaited mod of Crash Team Racing is finally here. Nitros Oxide joins the race and is now fully playable and selectable in all game modes, and most impressive of all, it runs on default 2MB of RAM. Thanks to Niko for all his hard work.
In this version, all characters and tracks are unlocked by default. Garage Selector mod is bundled, which means you can create a proper Adventure profile with Oxide, plus other unlockable characters as a bonus. We've seen no crashes in this particular build of the mod after weeks of testing, so if you find any issues, please comment below.

Playable Nitros Oxide v1.0 (NTSC-U only): mediafire.com/file/05hrg6zyenei02v/Playable+Nitros+Oxide+(NTSC-U)+v1.zip/file

HOW TO INSTALL:
You will need: Playable Nitros Oxide mod and Installation Tool.
1. Rename your CTR copy to "ctr_original.bin" and drag it into the Tools folder.
2. Click on _INIT.BAT to start decompressing the game files.
3. Replace the overlays 230_10 and 233_13 on "overlays" folder, inside "bigfile".
4. Replace SCUS_944.26 on "ctr_source" folder.
5. Click on _BUILD.BAT to rebuild the modded game.
6. Done! A file named "ctr_rebuild.bin" will be generated. This is the modded file you'll use to play. You can rename it and move it elsewhere.
If you still can't install the mod, check out a quick tutorial: youtu.be/xR1cdXkmvsg
We eventually plan to make a second release after the game is fully decompiled. We want to add more custom features to Oxide, such as podium victory, unlock method, a proper shadow, six exhaust smokes, start before green light, spinning out after attacks, proper tire marks, and more. Don't expect it anytime soon though, it will probably take a few years.
The following changes made this mod possible:
- Relocate "render bucket instance" from mempack to early-RDATA.
- Relocate pause-data from early-RDATA to later-RDATA.
- Inject assembly to later-RDATA, override pool inits.
- Relocate "small stack pool" from mempack to kernel memory (solid).
- Relocate "large stack pool" from mempack to kernel memory (divided).
- Shrink stack reserve from 0x800 bytes to 0x600 bytes.
- Override MPK loading in main menu (Arcade mpk to Adventure mpk).
- Hook main menu character select (menu + model search), to find Oxide.
- Append main menu overlay with new character select icon data.
- Append cutscene overlay with Adventure boss selection.
Naughty Dog, unlike Crash 1-3, did not use kernel memory when building CTR (region 0x80000000 - 0x80010000). This is because they used GameShark during development, which also needed the resources. With everyone in the community researching the game for years, we finally found how to relocate expensive memory into the kernel region, leaving enough memory in mempack to fit Oxide's model.
In the (not so close) future, there will be brand new characters added to the character selection. Stay tuned for more.

![Crash Team Racing (Aug 5, 1999 prototype) - Citadel City Relics [PART 8]](https://i.ytimg.com/vi/gI6eZgVIxrc/hqdefault.jpg "Crash Team Racing (Aug 5, 1999 prototype) - Citadel City Relics [PART 8]
The August 5th, 1999 build is a preview version of CTR built a month and a half before the final NTSC build date of September 24th, 1999. This beta version was widely given out among North-american video game magazines to be used in preview articles before the game is released.
A full documentation of the differences can found at: https://tcrf.net/Proto:Crash_Team_Racing/August_5th,_1999_build
Download the game, patched and ready to go: https://hiddenpalace.org/Crash_Team_Racing_(Aug_5,_1999_prototype%29
This build has protection to prevent people from using the disc outside of Naughty Dog, or their reviewers.
Protection level 1:
If the disc does not detect a special memory card dongle, then the game will not boot. It is as simple as if you see a string on the memory card, then boot. If the string is not on the memory card, then freeze. Interestingly, the dongles internal name is E3 dongle Copyright 1999 Naughty Dog, Inc., leading to believe that it was made specifically for E3 demo but later reused in subsequent builds.
Protection level 2:
After the game boots, there are 7 function pointers that are assigned incorrect values, which are incremented by an RNG before being executed. If a controller dongle is inserted, the controller will inject data into the RNG, then the RNG will increment the incorrect function pointers to the correct function addresses. Without the dongle, the incorrect pointers will execute, and crash the game.
In previous videos, we only had one function pointer working correctly, by setting a breakpoint before execution in no$psx emulator, and overriding the value manually. There were several bugs and instabilities.
Niko has spent over a year researching the retail game (94426), so within a few days, he finally was able to find how the entire function pointer system worked, and insert ASM that forces the RNG to return one value, which corrects all 7 function pointers, allowing the game to run.
Niko also fixed one of Naughty Dogs mistakes that was present even with the dongles, that would prevent the game from loading Relic Race on Slide Coliseum and Turbo Track.
In the link below, there are miscellaneous content for this prototype:
- GameShark codes that allow you to instantly beat Adventure Mode 100%, and unlock all rewards.
- A guide for playing the original ISO by making your own memory card dongle, and using GameShark to apply the rest of the fixes.
- We documented exactly how the ISO was patched, to learn how it was done.

This is the sixth preview video of the prototype of Crash Team Racing (PS1).
This gameplay is from the August 5th 1999, a beta version of the game built a month and a half before the final NTSC build date of September 24th 1999. This build is dongle protected, which means you cant play via normal means, so attempting to run it will result in a black screen. Were solving this problem, so it will eventually be released to the public. Dont ask for a release date because even we dont know and were also busy with other stuff, so please be patient and enjoy the videos.
A full documentation of the differences will be available at The Cutting Room Floor article, and a download link will be posted on Hidden Palace website. At the time, both pages are being worked on.
A HUGE thanks to almarkowbender, gdias/Darkaiser (me), Gh0stBlade, let-over-lambda, mementomori/madmarsrocks, Niko, and psx-collector for making this release possible.
Noticeable Differences:
- Tropys ghost is harder in this version, as he access some shortcuts that only Oxides ghost would do.
- Oxides ghost arent present in this build. Instead, you race against another ghost using the current players character.
- The ghosts are unfinished in some tracks (out of bounds), which is impossible to beat them.
- Menu differences: missing transitions, no exclamation mark in the texts, different X button icon, etc.")
