Not a whole lot to this update. We have patched in some fixes for the set files and the Act 2 camera (along with some other minor tweaks), and we have included some new textures that didn't quite make it in.

We also wanted to give a big thank you to the Sonic Hacking Contest this year! We managed to bring in some awesome trophies this year. And we just wanted to thank everyone for making the Hacking Contest so awesome this year. There were some awesome mods in there, and there was plenty of competition. We look forward to SHC 2019. We can't wait to see you all next year!


  • Several textures between all acts and objects have been tweaked to be made more accurate.
  • A suggested edit in issue #2 has been added. This does help the act play better.
  • A quick fix to hopefully deal with a possible bug with the DC Conversion mod. PkR was kind enough to account for our mod, so we have hopefully made them function together properly. If you still run into issues when running with the DC Conversion enabled, please disable Windy Valley in that mod just to be safe.

If you find any bugs, want to talk to us, or just want to throw someone our way, you can find me (ItsEasyActually) on twitter, or you can locate both supercoolsonic and myself on the X-Hax IRC or Discord server. We do request if you do find bugs, please post about them here

Welcome Everyone!

We have arrived at the launch day of our long awaited Prototype Windy Valley mod release! This mod aimed to port as faithfully as possible the original level data for Windy Valley that was located in the Sonic Adventure AutoDemo.

This entire mod has been a love project between our development team, and supercoolsonic and I have worked tireless the last week to release this in time for the Sonic Hacking Contest. And we have made it! The past year has been a wild ride, but we are pleased to release this mod to you! Thank you all for sticking around and patiently waiting for us to reach our release.


This entire level replaces the entirety of the original Windy Valley level seen in the release versions of Sonic Adventure DX. The level data and object models were found in the Sonic Adventure AutoDemo and lacked textures and did not natively function in that build of the game. This mod has taken the level data and object data and recreated it via code reusing the assets, but recreated the code from the ground up.

The objects seen in the game are recreations based on knowledge from footage and the "working" version of the level that user evilhamwizard created by modifying the AutoDemo's binaries. We also created a disassembly of the original binary for the stage to aide us in both located all of the object data and giving us insight into how the original objects were coded. There are some additional objects that we created ourselves to place into the game due to wanting to polish this highly unfinished level from the original data. The T_Spring object (yellow spring island in Act 2, original object to the level but lacked any model data), the bridge poles (did not originally exist), and several unreferenced models were added to complete the level. Additionally, there are gear and bolt objects added to the level in reference to the flashback scene from Amy's Story. These objects are not featured in the layouts, however if you wish to add them yourself in any layout modifications, please feel free to!

All of the textures were recreated as faithfully as they can be. Without the original texture data, we can only do so much to create usable assets that both resemble the original textures and keep up with a decent quality so it's not muddy in-game. We have done our best to use textures that retain the original feel and look of the level. This was one of the hardest parts of development, but we are satisfied enough at this point. These will likely continue to be updated as time goes on, especially if we ever see a build with the original textures in place.


You will need the SADXModLoader setup on an install of SADX. Please download the AD_Windy.7z file, and unzip its contents to the mods folder. This can be found in your SADX install with the ModLoader. Then open the SADXModLoader and select it from the list. Now you can boot up your game and the mod should be loaded. 

If you are a BetterSADX user, you can follow the same instructions to install this mod if you previously did not have it installed. If you have used PkR's installer, this mod is also included within the install. You can follow these same instructions as well if you did not install via that method.

If this mod is being used in conjunction with the DC Conversion Mod, please see below:

Please load the DC Conversion mod first. And please go into the configuration options for the DC Conversion mod and disable Windy Valley. Unfortunately, there are some conflicts of code between the two mods, and the easiest solution is to simply disable Windy Valley on the DC Conversion mod's end.

Special Thanks
