This mod attempts to restore Dreamcast assets (including levels, textures, sounds and some objects/effects) in Sonic Adventure DX PC. The main focus of this mod is porting Dreamcast Sonic Adventure Action Stages, Adventure Fields and boss arenas to SADX. Some level object ports have also been done to improve texture quality and restore missing detail, animations and effects. A companion mod called Sound Overhaul restores some of the deleted sounds and replaces most ingame sound effects with higher-quality sounds ripped from the Dreamcast version. The long-term goal of this project is to reproduce the Dreamcast SA1 experience in SADX PC as accurately as possible, including graphics, sound, branding etc. This mod is designed for use with SADX Mod Loader. It is split into several mini-mods which you can enable or disable independently.

Update 4 release!

News 10 comments

Update 4 for Dreamcast Conversion is now ready!

March 24 update: I've reuploaded the Update 4 archive with some minor fixes. This is primarily for people who haven't downloaded Update 4 yet. If you already have Update 4, most of the updates will be pushed to you through the Mod Loader. If you use the DisableSA1TitleScreen mod, replace its mod.ini with this one.

Download the full package here.

Be sure to install the mods in the correct order! Check the install guide for more details.

This is another huge update that brings a lot of new stuff!

Highlights of this version:

  • Mod updates: you may remember that Update 3 added support for mod updates through the Mod Loader. Today's Mod Loader update enables mod update functionality. As for the DC mods, many things have changed since Update 3, and several new mods were added. This version introduces support for modular updates. This means you don't need the MEGA mirror anymore, as the updates will be pushed to you automatically through the Mod Loader, and only the changed files will be downloaded! This was made possible thanks to ReimuHakurei, who offered to host my mods on his server. You need to download Update 4 for DC Mods and update the Mod Loader first to be able to use the new update system.
  • Dreamcast Chao Gardens, including the VMU transporter model for the Name Machine and the Chao Race track - check out the restored flowers and cheering Omochao! The secret egg found on the Egg Carrier now hatches a two-tone black Chao like on the Dreamcast. Two-tone black eggs have also been updated with SA1 textures.
  • A "Dreamcast General" mod that introduces several non-level specific fixes and replaces all non-level textures with higher quality Dreamcast textures (thanks Onso!). So now the entire game is using SA1 textures!
  • A new 16:9 title screen for the DC Branding mod that activates automatically based on your screen resolution/window size.
  • Dreamcast water textures in Emerald Coast! You can switch back to water textures used previously in this mod by enabling SADX Style Water.
  • An updated Sound Overhaul 2 (Dreamcast sound effects) mod is included in the main mod package.
  • A new "SET layout fixes" mod by Supercoolsonic with level layout fixes and improvements for various stages.
  • A totally insane amount of bug fixes and accuracy improvements, including material color fixes, object model restorations, cutscene models and lots of other things for many areas in the game.
  • A higher quality intro movie from the X360 version that retains the SA1 logo.
  • The HD GUI mod now includes upscaled level objectives and level title cards.
  • All PNG textures have been optimized with oxipng to reduce file size with no quality loss.

As always, be sure to also grab the latest build of the Palette Lighting mod by SonicFreak94. Note that you need to download the latest version from the master branch, as other branches are experimental and not intended for regular gameplay!

Enjoy the improved Dreamcast experience, and stay tuned for more accuracy updates!

Twinkle Park crashes for me in the main area. It has to do with something loading in, because with Sonic, I can go into the level, play the car section and ride the train for about two seconds before the crash, but Amy (and possibly Big) crashes instantly.

If you're still having the issue you described in this and other posts on this page, I would like to have a look at your SADXModLoader.ini in the mods folder (or at least a screenshot of your SADX Mod Manager with a list of mods and their order) so that I can help you.

I haven't been able to reproduce the crash with your mods folder (I reenabled the Twinkle Park mod, which I assume you had disabled because of the crash, also I can't use the Steam Achievements mod because I don't own the Steam version), but I noticed some of the mods and the Mod Loader are out of date. It's absolutely essential to keep everything, especially the Mod Loader, up to date, so try updating everything and testing again.

There are several mods that are listed as incompatible in the FAQ section, such as the Ocean Green mod and SADXFE Textures/Data (you don't need them if you use my mods anyway). Also, I believe you don't need mods like "waterfix" because my mods contain water specific to SA1 levels, and those other mods just make the game take longer to load and may cause issues with my mods. Most of the textures in "xinput-prompts" mod are overwritten by textures from the DC Branding mod and the HD GUI mod.

Finally, judging by how things are set up in your mod folder, it looks like the DC mods were installed over an older version of BetterSADX? If so, you need to seek help with the author of BetterSADX as I don't support mod compilations made by other people.

Another bug: the cutscene for the Light Speed Shoes happens at the SADX location. The camera at the end of the cutscene centers in on the DC location.

This is an amazing mod! I was quite surprised when I entered the SS Garden and found it to actually be different! And thank you for including the option to keep SADX water. SA1 water looks ugly compared to the SADX:FE - Green ECZ Ocean mod's water.
Any chance you could get in contact with MainMemory and add the No Gloss mod to the pack? The characters stick out like a sore thumb without it. :p
There is one problem I noticed quite early on in the game. The train model in Station Square seems to be missing, but the train is still there. It's fine in the Mystic Ruins, however.

Edit: The train is only missing in the daytime version of SS.

I do not have that problem. Most likely a bug with your game. PKR most likely doesn't have this issue, either.
Also, did you get the Lantern mod? If you did, wow. Never thought someone would really hate the game's lighting that much to force others to conform to their opinion.

I was playing through the game, and it seems like it was a one-time error I had when starting Sonic's story. It's working just fine now.
Also, I didn't know about the Lanern mod. I was referring to MainMemory's "No Gloss" mod. All it does is remove gloss from character models. I think I'll try it out though.

Please do, the Palette Lighting mod makes the game much better.
