Yes there is a mod for Sonic Adventure DX that puts it in widescreen. Download the mod here:


Step 1: After downloading the file, copy the .exe file in the .zip file into your game's root folder.

Step 2: After step 1, run the .exe file after copying. once in the programs menu enter the following:

File Name: sonic.exe.
Position 1: 2A81
Position 2: 2A82
Position 3: 2A8B
Position 4: 2A8C
(Enter resolution here)

Then click patch. the mod works best at the 1440x900 resolution. but any resolution should work fine, and there you go you now have Sonic Adventure DX in a widescreen format.

Extra Info:

1: After applying the mod you now have to run the game through the sonic.exe file from now on.

2: Also when in cut scenes or menu's there will be a black bar on the right side of the screen, don't worry the black bar will not be in there when playing in a level or hub world.

3: The mod patcher was created by Squ1zZy so all credit goes to him.

Thank you. -1NaCsTeR

I know I'm bumping a topic from ages ago, but there have been some developments I've run into while playing with hex editors that allow this to work on {LINK REMOVED} (PC 2003 version)
I would post this on that sonic retro topic, but they still haven't approved my account on their forum because of some elitist ♥♥♥♥♥♥♥t.

download SADXFE for Sonic DX 2003 from link above and install it, following all it's instructions on that forum post.

Next, follow steps 1 and 2 from the above post, then use these settings instead.

Filename: SADXFE.exe
Pos1: 29DD
Pos2: 29DE
Pos3: 29E7
Pos4: 29E8
and use any resolution with a height greater than 768.
(720p works, but will cut off half the life meter and the small animals doohickey.)

Lastly, In the SADX autorun, set the resolution to 1024x768, as that is the resolution these positions allow unipatcher to edit. (alternatively edit sonicdx.ini and change the "screensize=?" to "screensize=2")

Same issues as above, the menus are all screwed up, but all is well in-game.

off-topic rambling
Fixed edition also has the same patches that mainmemory's superfix exe has, so if you want to use this with Super SADX, download and install SADX Fixed Edition from here ( following all the instructions on that page AND patching with unipatcher as described above. THEN rename SADXFE.exe to sonic - superfix.exe and download the Super SADX mod, and place it in your SADX install folder. All will work properly and the resolution patch should still apply. :D Hurrah, Super Sonic Adventure DX Fixed Edition HD.

If you wanna run in a window, I recommend using DXwnd with the game still set to windowed in the autorun, because SADX PC 2003 is terrible when running windowed, no scaling or window resizing. Pssh. >_>

Hopefully this helped someone. :)
