Everything you need to know to speedrun SADX

Alright, I read a lot of questions about Sonic Adventure DX stuff, so I decided to make this thread to hopefully answer all of your questions.

First, you all guys should watch this:

Still some stuff? Alright, let’s take a look.

1. Which version of SADX is the best for speedrunning?

It’s PC disc (2004), yes, forget Steam, it’s slow, has a lot of issues, bad loading, bad controls and I’m pretty sure you want to go fast. Keep in mind that we are talking about steam vanilla, since better sadx is not allowed.

2. Can I take the disc .exe file in the resources section and put it in my Steam folder?

No, if you want the Disc version, you must buy or download it because every files are different than Steam version.

3. You guys talk about some “mods” in the rules, why?

So this is kinda complicated, we decided to allow few very specific mods for PC Disc, because the vanilla game is so broken that it's close to unplayable without. For example, if you have a xbox controller you will experiment an issue where the camera will always spinning, making the game unplayable.

Therefore, we decided to allow few mods (mostly fixes) to make the experience better. That being said, we still want to keep the game as close as possible to the vanilla version, so any textures, level mods etc are not allowed (Exit DC Conversion, SADX FE etc.). If you are unsure about which mod is allowed, you can check the rules. You can download all the allowed mods in the Resources section btw.

4. Can I use mods on Steam version?

No, mods on Steam version are not allowed, because the only way to use mods on this version is to install Better Sadx, this mod replaces all the games files and makes IGT impossible to use… so yeah... no mods for Steam. Also, in case that wasn't clear: BetterSadx is NOT allowed. Again, the best version is PC disc (2004), which you should be able to download or buy somewhere.

5. What is “CCEF”?

CCEF (Camera Code Error Fix) is what SCEP (Steam Camera Emulation Patch) was ment to be. It’s a mod that keep the camera you selected in the settings when you die or go to another zone. You can use it if you feel more comfortable with it. The SADX 2004 disc release had all of the code to reset the camera back to the selected option while changing zones or dying, but due to a development error in the code it never worked.

6. How do I use mods?

You need SADX mod manager, everything is explain on Lemres’s video on the top on this post.

7. What is “route variation”?

So in SADX, for some category we can use different route. As for Sonic story, there are 3 routes possible, Linear route, Glitched route and TAS route. If you are a beginner, you should learn “Linear route” Gpro made a really good tutorial for it, it is in the guide section. Top runners use “TAS route”, it’s kinda faster than Linear route, but really hard to optimize. Forget Glitched route, it’s just slow.

As for Tails, Early Ice Cap is slower by 2-3 secs. The only reason people does this route is because of how difficult Ice Cap TAS Strat is.

As for Gamma, you should directly learn “glitched route” it’s definitely faster than “linear route” and not that hard.

8. What is “IGT / in-game time”?

Oh boy, there’s a lot of question with this, so let's take a look:

IGT means in-game time, it’s generally used when the RTA is not fair enough. In fact, we call that IGT but as for SADX, it's more like "balanced RTA" because the game runs to a totally unstable framerate (depending on the hardware / OS and other factors.) For example, the game is running faster on Windows 7, so we have set up a Balanced RTA (or IGT whatever) represents the what your time would be if there were 60 frames in a second. So as for SADX, “IGT” is like a frame counter.

9. How do I set up the IGT? There is now a functional PC disc autosplitter which includes IGT script, to activate it, simply open Livesplit, right clic and select "edit splits" then clic on "Activate". DO NOT TURN ON THE AUTOSPLITTER IF YOU ARE USING THE STEAM VERSION.

If you play on Steam, OR if you don't know how to display the IGT on Livesplit, you'll need to follow Argick's tutorial here: https://www.speedrun.com/sadx/guide/aryzs

10. Why is my IGT higher/lower than my RTA?

This is quite normal, again, the game doesn’t run at a stable 60 fps, so if your game is running faster than 60 fps (which is common) the timer will accelerate. However, it will slow down if your game is slower than 60 fps (or if your loads are just bad.)

11. I play on console, should I use IGT?

No and you can’t anyway.

12. I'm using Steam version and IGT doesn't work.

Make sure you don't use any mods, such as BetterSADX, and try to reinstall the game.

13. I installed IGT but the two timers are identical.

This usually happens when you have not configured the IGT and RTA display correctly. You must go In "Layout Settings" select each "Timer" tab and ensure one is set to "Real Time" and the other "Game Time" otherwise it will not work.

14. I have an old run with just RTA, is it possible to calculate the IGT of this run and add it?

No.

15. Why did some runners delete the voice files from the game? I don't get it.

It is to avoid lags. You can miss some important tricks because of the voices, like egg hornet one cycle. If you are curious, It's allowed to delete the voice files because the launcher for the official disc literally let you play without voice clips, music, and/or sound effects.

16. I want to speedrun Sonic's Story, where can I start?

Cool, once your SADX is ready, you can start learning Sonic's Story here:

17. Is there a tutorial for other categories?

Tails and Knuckles are also available in the guide section. You can also join the discord if you need any extra help: https://discord.gg/NCUdvEwWMA

If you guys have still some questions, feel free to ask here. :) Good luck and have fun with SADX, remember this game is hard, but it is consistent.

Hello @Sora, I downloaded the disk version to play on my PC but the game crashes on the second blow I hit on the chaos, if you know any way to solve this I will be grateful.

Note: I've downloaded several and always give this error.

SADX Pre-IGT Era Archive

You may have noticed some very old runs being rejected. This is because we have decided to archive the leaderboards done prior to IGT becoming the main timing method. Prior to archiving, most of the runs prior to April 22, 2018 were at the bottom of the leaderboards due to only having RTA timing, wh
