Install

Attention Streamers:
The BetterSADX mod (and the base SADX 2004 game) tend to be crashed by XSplit and there's more or less nothing we can do about it. The exact issue is difficult to reproduce and has caused multiple problems in the past for various streamers. If you plan to stream something using BetterSADX or SADX 2004 Mods, we recommend OBS.

New in 4.3.1
We've included a couple of small mod changes in this one and reduced the installer back down to about 900MB once again- sorry for the previous release being so large. We've added automatic resolution detection for when you install it, so the game will run in your native resolution by default, and in addition, we've brought everything up to date as well. This release includes 2 new mods, Perfect Chaos Music Swap (which swaps the music for the final boss around because apparently that's something people wanted), and also a mod for Xbox 360 input prompts.

One feature we'd like to highlight that has actually been avaliable a while now is integration with the popular modding platform GameBanana[gamebanana.com]. By opening the SADX Mod Manager, and going to the options tab and clicking on "Install URL Handler" you can add support to your PC for 1 click SADX Mod Installation through GameBanana's SADX2004 section.

If you happen to use another controller other than the typical Xbox 360 pad, we suggest heading over there for mods that do the same thing but for other gamepads, such as Dualshock 3 and 4, and the Xbox One controller.
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.

DLC Mods!
Added in 4.2 is all of the wonderful DLC mods by PkR! These mods allow you to experience the original Dreamcast DLC at any time by toggling them from the Mod Manager! Simply open the game and choose configure to bring up the mod manager.

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.

Is there any reason why Red Mountain causes the game to basically freeze?
I got up to it in Sonic's story, and after the short cutscene of the Egg Carrier flying by, the music starts, but the screen is locked on it for a good while, then cuts to the starting point with an FPS of about 1.

Hey there! I'm new to the whole SADX modding scene, but I'm really enoying what I've been able to do thus far. The only question I have for right now is, simply, where can I find more mods than the ones listed within this guide? I've already saved the GameBanana link to my Bookmarks and checked out MM and SF94's pages--besides the extra levels listed, are there any other hot spots for SADX mods? Thanks!

@Sonic Warrior
Another way to fix the minigames being tiny is to run SADX at a resolution where 640x480 isn't too small. (e.g 1366x768)
ChocIce75 Apr 16 @ 6:19am 
Only if you disable the Steam Achivements mod.
Deep Weeb Apr 15 @ 9:23pm 
Are achievements affected by this mod?
cheatfreak47  [author] Apr 10 @ 11:28am 
Yes that is the only way for now.
Sonic Warrior Apr 10 @ 8:55am 
I have a question, In the mini game menu, the games are very small, is the only way to enlarge them is to play in the original 640X480 Resolution?
