Codebreaker codes for Widescreen not always working, but patching the game ISO works?
#1
Hello people!
I've been trying to get this to work the way I want and I simply can't! So I was hoping that you could help me...
I have a PAL FAT PS2 with the latest FreeMC installed and the latest OPL. I'm running my games (all of them are NTSC region) from the HDD. Things work great in general. I can use codebreaker codes for cheats and most of the time they work fine. Up until recently I've used the CBv9.2 (patched etc etc) and now I decided to switch to CBv9.3 (patched etc).

Now to my question... I've been trying to make some of the games work in widescreen and I had some success. What I mean is that some games work great with the codebreaker method (ex: Dead or Alive, Zone of the Enders) while some others are either not working (Kingdom Hearts gives black screen) or they work as if the Codebreaker Code is not there (Dragonball Z: Budokai works in 4:3 with the Codebreaker code on) or they work but appear semi-broken (Prince of Persia: Sands of Time). All of the broken games are working fine in Widescreen mode If I run them from the latest PCSX2 emulator using their pnach file or if I patch their ISO using the PS2 patch engine.

Why is this happening? Is it a limitation with the codebreaker or am I doing something wrong? I would really like to have the games unpatched on the HDD and if I want to enable the Widescreen patch, to use the codebreaker code and not have them permanenrtly patched. I will attach a few photos of POP: Sands of Time (one of the semi-broken games) to show you how it looks on the real hardware using the codebreaker widescreen code:

You can try PS2 patch engine.
This app will patch your iso with pnachs or raw codes but not all cheats codes are supported.

edit: I have found this software at psx scene.

The problem is your codes are wrote in 8bit constant write. This means the code only writes the last two digits at the given address instead of all 8 digits. The codes below will work.

Thank you soooo much! Finally someone answered! It worked wonderful! You made me very happy! Smile You can't imagine how frustrated I was... I really tried to fix this all this time but I couldn't find the answer anywere... Again thank you!

So, do I just replace the "00" at the beggining with "20" for all the other widescreen cheat codes that didn't work and had "00" at the beginning? And why "20" and not some other number?

If converting from pnatch then yes. I'll explain how each works.

8bit
01234567 dddddddd

16bit
11234567 dddddddd


32bit
21234567 dddddddd


Yellow is the command for how to write the data. The green is the data that will be changed in game, the blue will be ignored. The red is the address.

Your codes failed to work because the code only changed the last 2 digits of the data. If I remember correctly all pnatch codes are 32bit constant write.
