Updates
Please join the Steam group and/or sign up for email updates to be notified when BetterSADX is updated.

Occasionally the SADX Mod Manager has updates. If you wish to manually update it, read this.

New in 4.1.1
Includes the latest SADX Mod Loader, bringing new functions like the much requested Menu scaling, and includes the latest versions of each mod at the time of the release, and other small small tweaks have been made to mod-order and what is enabled and disabled by default.
Features
Dreamcast Conversion
A new feature added in 4.0 is the inclusion of the incredible Dreamcast Conversion mod by PkR, TheArcadeStriker, and SonicFreak94. This project aims to return the PC version of Sonic Adventure DX to it's appearance on the original Sega Dreamcast. This includes the restoration of the palette lighting engine, as well as ports of the Dreamcast land tables, level models, and textures.

Resolution Options
Use any custom resolution. With “Windowed Fullscreen” and “Stretch Fullscreen” (enabled by default), you can specify resolutions larger than your native which will downsample.

Improved Graphics and Fixes
Texture filtering, Mipmapping and an extensive range of layout and bug fixes, created by the community.

Mod Support
BetterSADX includes and relies on the latest version of SADX Mod Manager, which provides a clean entry point and effective way to manage mods for the game! All of BetterSADX is fully modular, meaning, you can configure and tweak it here to your heart's content. Some of these mods now support automatic updates.

Full Controller Support
Includes the latest version of the Input Mod (By SonicFreak94). This provides improved support with use of the right stick and trigger buttons. It also includes Smooth Cam to give you a smoother first person camera.

Super Sonic in Action Stages
Once you’ve completed the 7 main story modes, you can play as Super Sonic who is faster, invincible and can run along most water. He loses 1 ring per second and will lose the power once his ring count hits 0.

To activate:
  • Make sure you've completed the Super Sonic story at least once.
  • Play as Sonic.
  • Collect 50 rings.
  • Jump and press the B button to transform into Super Sonic (or to transform back).
Please Note: Some stages and items/set-pieces (which force you to spindash) will auto-transform Sonic back to his normal form to stop the game from crashing. If you are unable to transform for this reason, Sonic will say "Huh?".

In the past, this feature was restricted to Super Sonic Adventure mode, however, it is now usable on any save file that has the Super Sonic story completed. It's possible this will change in the future, however.

Additional Twinkle Circuits
There are 5 additional courses that were used on the Dreamcast through their online service and were previously inaccessible on PC without hacking. You can now access them via the Trial Mode's Subgame menu with one new course for each character.

To unlock the Subgame:
  • Sonic, Amy, and Big have access to it after they beat Twinkle Park.
  • Tails, Knuckles, and Gamma can access it after finding a pass in the grass obtainable after beating their respective stories.
The original Twinkle Circuit can still be played in the Adventure field for all characters.

Playable Game Gear titles
The Game Gear games from previous SADX releases are back.
  • Sonic the Hedgehog
  • Sonic Drift
  • Sonic Chaos
  • Sonic Spinball
  • Sonic Labyrinth
  • Sonic the Hedgehog 2
  • Dr. Robotnik's Mean Bean Machine
  • Sonic Triple Trouple
  • Sonic Drift 2
  • Tails' Skypatrol
  • Sonic Blast
  • Tails Adventure
You can unlock them by collecting emblems and beating missions in Mission mode. It is recommended you run the game in 640 x 480 if you plan on playing these.

Seamless Integration
You can enjoy all the features just from running the game via Steam and choosing Play or Configure, and in addition, this also supports Steam Achievements.
Configure
When you launch the game from Steam, you can still choose “Play” or “Configure” to change settings. Other than the resolution, we recommend you leave the settings as their defaults.

Configure Mods
Configure opens the SADX Mod Manager, where you can manage and tweak what we've provided to you in any way you'd like. We've included the mods in the optimal order by default as well, but for future reference, mods have a priority system. The lower on the list the mod is, the higher the priority for that mod is, meaning if multiple mods replace the same thing, only the lowest one on the list will show it's changes.

Set your resolution
To set your resolution:
  • Start the game from Steam and choose the Configure option.
  • Click the “Options” tab.
  • Next to “Use Custom Resolution” you can specify your own or click the “Native Resolution” button to use what your Desktop is currently set to.
  • Click “Save” and close the window or click “Save and Play”.

VSync & Anti-Aliasing
To enable these features, you will need to configure them via your graphics driver control panel.

As of 3.4, there is an experimental V-Sync toggle for when the game is ran in True Fullscreen as opposed to Windowed Fullscreen. It is recommended that if you are running Windows 7, 8, or 10, you have the Aero mode enabled, as Windowed Fullscreen actually relies on Aero for vertical syncing.

Converting your Steam saves
This is now done automatically during the install.
If a "savedata" folder already exists in your game folder from a prior install of BetterSADX, then no saves will be copied (to prevent overwriting and save loss)

Speedruns
We love speedrunners! <3

To show this we have provided a easy method, legal method to access to a speedrun-legal copy of the game.

This is now accessed when installing BetterSADX- via the Minimal / Speedruns install option.
Choosing this will perform only a basic install consisting of the SADX Mod Manager and the following mods.
  • Camera Code Error Fix
  • XInput-Fix

Additional Speedrun Related Notes.
  • If your game runs at above 60fps (~63), you may enable Frame Limiter by SF94, which is included when you install in Minimum/Speedruns mode for more precise frame-capping- which will hopefully remove that discrepency in timed speedruns. Only use this if you need it!
  • BetterSADX 3.5 is the first version made to be Speedrun oriented, no versions below 3.5 should be permitted for use by speedrunners.
  • As of BetterSADX 3.6, speedrunners do not need to do anything to mitigate the voice lags that cause difficulty in one-cycling the Egg Hornet with Sonic. The change that corrected this issue was the shift from voices using WMA to ADX, this change also mitigates all other voice lags throughout the whole game. Special thanks to SonicFreak94 and MainMemory for this new feature!
  • As of BetterSADX 4.0, the patcher now has a Minimal Install mode, made specifically for making the game suitable for speedrunning with no additional configuration necessary.
  • Input-Mod is technically also allowed, but we reverted back to XInput-Fix for 4.1 because of a possible bug. If updating from 4.0 it will stay installed, but new installs come with only Xinput-Fix.

How do you change the controls?
Isolated Rainbow Jun 14 @ 8:35am 
Yes, It will allow you to play from there. Just make sure to always backup your save. Check PC Gaming Wiki to find the destination for the save to backup.
Luke Skywalker Jun 14 @ 7:42am 
Hey. I haven't downloaded it yet, but I have a question. Are regular steam saves compatible with Better SADX? Cause I beat all of the stories and most of the trial missions on my regular steam save. So will Better SADX make me create a new save file? Or can I use my old save with Better SADX?

Hi there! I noticed a bit of a problem with the mod, specifically in Amy's Final Egg. After climbing up the wall inside the elevator, Amy steps ouside and... the game crashes. This doesn't happen all the time (It's about 50/50 whether it crashes or not), but it didn't happen in the original SADX. It might have something to do with Zero's positioning before stepping in the elevator, as it's more likely to crash if he's not in the elevator area. Is this something that can be fixed?

I should mention I am on BetterSADX 4.1 and am using the Dreamcast Conversion Mod.

Thanks!

@DJ KAZiBA @Zeldaplayer59 Yeah I was afraid that might be the case. I still don't understand what triggered it as I wasn't running the game with any mods or cheats outside of BetterDX itself but ah well. The rest of the game outside of storymode seems to work fine so I'm just going to keep things as they are for now.
I still have this game on every other system so it's not a huge loss.
Zeldaplayer59 Jun 3 @ 2:28pm 
@The Crimson Emo I had a similar issue on my Gamecube version of the game, except i experimented with cheat codes. Did you use anything sequence breaking? Of you did, the only option is to delete the saves. I don't think the 'unlock all characters' code counts as sequence breaking

Hello, so I had been playing Sonic Adventure, so the game was working perfectly fine, but once I installed the update, it is unable to play. I notice in Task Manager that it starts running, then quits for some reason.
Rawk Hawk The Flying Man Jun 1 @ 1:17am 
Hello, I installed the update, but now the game refuses to start. Whenever I click Play, it starts and then quits. I'm not quite sure what the problem is.
DJ KAZiBA May 31 @ 5:55am 
Crimson Emo: I suggest you remove Sonic Adventure completely, including BetterSADX, delete all save games, reinstall the game and reinstall BetterSADX. Either your saves are corrupt or something major about your game is bugged.
The Crimson Emo May 29 @ 2:26pm 
Sorry for continuously spamming the comment wall, just wanted to chime in one last time.
I went through all of the characters stories and as expected, Sonic and Super Sonic are the only two I can complete and every other character is unbeatable. They randomly skip entire portions of the game and any cutscenes that would trigger them to go to Tikal's world so without a save editor, there's basically no way to finish the game.

I don't know if anyone else is experiencing this but incase they do, I linked the download for the mod below. It sucks to cheat but there's basically no other way of finishing the game. (At least on my end)
