PSOne Dithering OFF patches
#1
Welcome to the official thread for PS1 Dithering OFF patches - sister thread of PS1 Widescreen patches thread since the method is the same (find a known value responsible of dithering and replacing it by another one that turns off this effect).

Similarly to the other similars threads, here you can discuss, post and request Dithering OFF patches for PS1 games.

Since PS1 PC emulators can deal with dithering with no codes, these patches are mainly to be used on real hardware (or PS1 emulation on PS2 using POPStarter for example).

The latest collection of patches (as GS/AR code or HEX codes) is provided at the bottom at this post.

PS1 Dithering OFF patches started (here) when demilich dig up a twitter post from Chris Covell. You can see in attachements Chris' first codes. Big thanks to him.
  • Tutorial (WIP - last edit 2018/03/11) :
Requierements :

* no$psx ;
* E1 tool (made by krHACKen) ;
* CEP.

E1 tool will scan no$psx game snapshots and give you all the potential codes to dither off your games. It only accepts no$psx uncompressed snapshots (in no$psx : Options/Emulation Setup/Files/SNA File Format = Uncompressed).

Steps :

1. Load your game in no$psx and make a snapshot (File/Write Snapshot). Save the .SNA file in E1 folder ;

2. Drag & drop your snapshot on 20180227.BAT file ;

3. You will now see a new file named CHEATS.TXT in E1 folder, open it ;

4. Example : Crash Team Racing (PAL)

Quote:/* - 02h/03h/06h/07h/0Ah/0Bh/0Eh/0Fh - */

/* - LOST||CONFUSED||FUXXED - */

Nuthin'

Each double-line is a potential code to disable dithering - correctly written in GS/AR format (ready to use). We will now need to use CEP to test and eliminate the false positives, to only keep the adresses responsible for the dither effect. Most often, the line that contains "// Possible E1000200h : " is the main adress responsible for dithering.

5. Open CEP (run CEP.EXE) and set it up like this :

   

Process tab

   

Cheat tab

6. In CEP, on the process tab, click "Search" to attach CEP to no$psx ;

7. Now, copy & paste the codes from CHEATS.TXT file to CEP Cheat tab and click "ON" to enable the codes. See what happens in no$psx. Sometimes, dithering is placed at several adresses in a game (like in CTR example, the ones I marked with "*"). You need to test all the potential codes, one after one.

8. So I found 4 codes for CTR that remove dithering. This gives us as code :

Code:
#CTR Crash Team Racing (M6) (SCES-02105, SCES-02105/P)
//Disable dithering
D00217F8 0A00
800217F8 0000
D003F7C8 0A00
8003F7C8 0000
D006E630 0A20
8006E630 0020
D0073F48 0200
80073F48 0000

9. Done. Feel free to submit your code here.

Silent Hill looks without dithering ugly as...

Blink the colors are off and pop-ups are more visible. Looks like the game was designed based on dithering.

Hummm, weird. I ended up with 2 possible codes and none of them work.

(1) 80093688 0000
(2) 80095024 0000

Tried on PS1 emu on PS2 (POPStarter - USB mode) - I still havent find a way to check if the codes work on epsxe...

Can you share yours ?

Nice one, even though disabling dithering means really nasty banding aparent mostly in games with flat shading, like Motor Toon Grand Prix. Just turning off dithering will do nothing to make the game render all those inbetween shades that the game engine actually expects to be there and get corrected with dithering. You will need somekind of way to force the game to render at 24-bit color-space to alleviate this issue.

Chris Covell's PlayStation 1 Dithering Removal tutorial is online. Requieres no$psx. Easier than what I described in first post. You can test the changes in real time (and also make screenshots). Some games might be hard to hack...

Code:

My first attempt:

Code:
#Ridge Racer Type 4 [PAL] (SCES-01706)
//Disable dithering
800940E8 0000

Picture looks overall more clear but the textures and the sky have a more rougher look.

Nice.

I was trying to fix this problem :

   

This code doesn't remove dither during intro sequence before a race.

MGS gives me headaches...

The next one:

Code:
#Tenchu 1 [US] (SLUS-00706)
//Disable dithering
8007D42C 0000

Improves the overall look of the game IMO. Unfortunately this code is not compatible with the widescreen code. The whole sceen is distorted. Not sure why.
My next attempt will be MGS (german version) and GT1 or/and 2.
