If, for whatever reason, activating the autosplitter/IGT on Livesplit doesn't work, use this as the "Scriptable Auto Splitter" in your layout. This only works for the PC DISC version of the game. (external link)

This is the file to be used in the "Scriptable Auto Splitter" section of livesplit to calculate the IGT while running the steam version of SADX. This is ONLY compatible with Steam vanilla. if you are looking for the pc 2004/disc version, simply activate the autosplitter on Livesplit. (direct download)

CCEF (Camera Code Error Fix) CCEF is what SCEP (Steam Camera Emulation Patch) was ment to be. With the help of an awesome SADX modder called SonicFreak94 (the creator of SADX:FE (Sonic Adventure : DX Fixed Edition) we have a fully working SADX 2004 Disc Camera which doesn't get changed back to auto cam apon "dying, loading a zone/act; level, gaming over or quiting to main menu". This is not a mod or a hack it is a FIX similar to the Xinput Fix for X360 controllers. This is a fix because the SADX 2004 disc release has all of the code to re-set the camera back to the selected option but due to dumb devs mistake a few bytes ( 8 bytes in total) were a wrong instrution (code was "mov" when it should of been a "or" all this fix does is make it what it should have been. This Fix requires the SADX Mod Loader. (external link)

Egg Hornet can make SADX crash after defeating him when you skip the cutscene as Sonic, but sometimes even as Tails. This is related to a positional check that gets called in relation to the dock in mystic ruin. This mod disables that check and prevents the crash all together. (direct download)
