PSOne Dithering OFF patches
#11
Code:
#Gran Turismo 1 [PAL] (SCES-00984)
//Disable dithering
80087COC 0000

Looks great.

MGS is a hard one. I was not able to find the correct address. There is one thing which is annoying using no$psx. After searching in the hex decimal window (right mouse click and selecting "go to") my next search in the upper window triggers no$psx to freeze. I need to restart it. Any idea what I am doing wrong and how to fix it?

Chris Covell Wrote:You should dump a full disassembly of the game (from $80000000 to $801FFFFF) to a text file and search it for "E1000200h" or "E100000h" (or even "E1000600h", anything with bit 9 set.)

In no$psx, goto $80000000 in the disassembly window. Then Utility > Disassemble to File > Number of bytes to disassemble : 210000. Then save it as text file.
Use Notepad++ to open this new file, search E1000200h occurences. Then back to dissassembly & HEX windows. Wink

Not sure if I need a separate code for disc 2 of Driver 2. I will have to look into that.

Can someone try the Driver 2 dithering code I found on real hardware? For some reason it freezes on loading screen. I'm using a PS1 w/Gameshark module and original disc. I want to see if someone else gets the same issue.

Thanks

I couldn't get my dithering off code for Driver 2 NTSC U v1.0 to work on real console. Luckily I found a working version of of the dithering off code by "krHACKen" on the site shared by ShaolinAssasin. Thanks for the share! BTW I also managed to get it to work with the widescreen code at the same time.

Small disable dithering dump. I found an enable dithering code for Fear Effect. It seems like games with pre-rendered backgrounds that are in 4:3 aspect ratio do not have any dithering that I found. I may be wrong on this. Resident Evil, Alone in the Dark, and Fear Effect I found no disable dithering codes. Fear Effect seems to be anamorphic widescreen with FMV backgrounds. If anyone is able to double check that these work on actual hardware that would be great.
