This mod restores Dreamcast assets (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 5 is here!

News

Update 5 for Dreamcast Conversion is now ready!

Download the full package here.

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

Having issues? Check out the troubleshooting guide.

This is a complete mod package containing the latest version of each mod. If you update regularly through the Mod Loader, you don't need to download it because the updates are pushed to you automatically, which means you're already playing Update 5! This download is mainly for people getting started with DC mods.

I'm sure many of you have already seen some of this stuff in the changelog and the actual updates, but here's a list of highlights of this version:

  • SA1 ocean wave effect in Emerald Coast! You can see it in Act 1 during the whale chase sequence.
  • Various effect restorations, such as the explosion particles when you hit Perfect Chaos, Egg Hornet digging rotation and car headlights in Chaos 0.
  • All level mods are now using original PVR textures from the Dreamcast version (with some custom PVR textures where needed). This means everything loads a lot faster and is more faithful to the original game.
  • SADXStyleWater and some other mods are now using the new PVMX archive format developed by SonicFreak94. Make sure you update the Mod Loader to the latest version to avoid crashes with those mods!
  • A huge number of models had to be replaced by their Dreamcast counterparts due to texture mapping differences caused by the switch to original SA1 textures, which improved accuracy greatly. Many objects throughout the game are now using their original Dreamcast models - from plants in Lost World to Sky Deck cannons.
  • The SADX Style Water mod has been updated with support for animated water waves, also the seashore area in Station Square looks a bit closer to the original SADX seashore now.
  • A new optional mod restores the cowgirl from the original Japanese version of SA1 in Knuckles' Casinopolis. She even makes a noise when attacked! Though you need Sound Overhaul to hear it because her sound was removed in SADX.
  • Updates for DC Branding include title screen and main menu background improvements, as well as the gradient-filled rectangle that appears when you pause the game.
  • The SET layout fixes mod by supercoolsonic has been updated to include more level layouts.
  • Lots of general bugfixes and accuracy improvements.

I hope you like the new update. This update marks another milestone for Dreamcast mods, and a full restoration doesn't seem so distant anymore.

Enjoy the Dreamcast experience, and be sure to stay up to date!

Any chance at replicating the Level design of the original Japanese version?
Namely, the unsyncronised spiketraps in Lost World, or other small things?

I have a feeling the Lost World things and most level layout stuff are probably SET file related, in which case they would be relatively easy to restore. While this probably won't go into the main mod, you could contact the author of the SET Fixes mod, and he might be able to include it in his "SET Fixes+Extras" mod. Github.com

Ok, I may just do that, also this is some amazing work, I have to wonder, at the rate you're going, will you have anything left to show off by SHC2017?

SADX mods usually don't do very well in SHC, also my mods require the Lantern Engine (palette lighting) mod for best looks and visual accuracy to the original game, so there's that nuance too. I did help with the development of the PL mod, but it isn't my project, so even though people tend to use them together, they can't be submitted as a single contest entry unless we submit it as a team with SonicFreak94. So I don't know if I will participate at all.

As for what is left to show off, I generally try to push new content as soon as I get it working, and at this point there isn't too much left to restore. There's some Chao stuff I want to look into, and there are a few things with the PL mod that I can do together with its author to improve lighting accuracy. Also I want to add more graphics to the HD GUI mod when the Mod Loader gets their scaling support done, and I want to have a go at editing a couple of cutscenes too. And that's pretty much it. There are a few transparency-related issues that aren't really fixable without in-depth hacking of the game engine, which I can't do but at some point those hacks may become possible, and those issues will become irrelevant. We'll have to wait and see.

Which is a shame as SADX modification is far more difficult, mainly due to the limitations of the engine. it has to have custom code injected, and the main EXE has to also run it seemlessly, while still playing the game as normal. Before the mod loader, a project of this scale would be merely a fantasy, I mean, we're closer to understanding the issues that early CHRMODELS.dll mods were never able to find solutions too, namely Morph Targeting, Cutscene animations, and Vertex Welding, which made every custom Model look out of place (kinda like SonicFreak94's Super Sonic Mod, with the segmented limbs), and It'sEasyActually (Darkspines35)'s Dreamcast Models mod will be proof of that, and If nothing else, I truly appriciate what you guys do, even if you won't be participating.

Are you thinking of restoring the water effect on the title screen?

I've released an experimental water ripples mod and I'm currently running a hardware survey to see how well it performs. See here: Github.com
