#PCSX2 WIKI PATCH#
Go ingame and use your green herb to help Claire to recover her health and then jump back into Patch Finder. So now we have eliminated all those useless bytes can prevent us from finding the only needed one. You will have to repeat this process by entering back in game playing a small its portion (entering the new area, changing or firing weapons, etc.) and coming back to this menu until the number of bytes left will be almost unchangeable (it will stay around 2-3 million). Now the number of result bytes is decreased by many thousands maybe a million if you're lucky enough (see Intermediate stage picture). There are no changes in Claire condition from the last time so set the options as Equal and Old Value (we're leaving only those bytes not changed from the previous search). We can see that the page is still holding our previous search so now we will search in those 13,5 million bytes left (we need to find only one!). We'll need to walk around a bit (make a few steps) and press ESC again getting to the patch finder by Misc- Patch finder menu. Let's hit Close button now and return to game by Run- Execute. The program will find some 13 million values not equal to zero. As the Claire health must not be equal zero now (or else she would die) let's select Not Equal, compared to Specific Value and place a zero in the edit box. Let's assume also that the condition cannot be less than zero ( unsigned) although it will not make much difference if we would assume otherwise.Ĭurrently this dialog holds no data this is its starting state. Every byte has 8 bits and it is the smallest data unit so we will select 8bits size. Assuming the main work is done by EE processor let's start to search for our condition byte in EE RAM. The dialog allows us to search through EE RAM and IOP RAM. When you get to the safer place (it may prove harder) press ESC and choose Patch Finder.

It's quite easy to take any amount of damage in this game so it won't be a problem. We will need to vary this value to catch it so Claire has to take some damage and find a green herb to be able to restore it. There is a byte or a word (2 bytes) somewhere in the game memory that is responsible for storing the Claire's condition.

Our first priority will be to make Claire immortal so her condition will steadily be in green. The game starts in a prison with only a knife for a weapon.
#PCSX2 WIKI PLUS#
This is not a simple game to play and it's quite simple to cheat plus you may need some cheats playing it. This tutorial will cover the game Resident Evil Code: Veronica X. pnach (for example a patch for Drakan 2 PAL has name 04f9d87f.pnach). When you create your patch it will be placed here as well and will have the name. These are the default ones to improve some games behavior (they skip videos or some sections in otherwise hanging games). Your installation of PCSX2 may already have many patches in it. Each save state of a game is saved with the CRC number of that certain game.(edit-dhillel)Īll the patches are stored in the patches folder by default.

This is a precaution not to apply the patch created for one game version on another making the game unplayable/crashing. It helps to distinguish not only the different games but even the different regions and the different editions of one game. This CRC is a special control sum of all bytes in the main game executable.
#PCSX2 WIKI HOW TO#
Here goes a small tutorial that can help you understand a bit how does these cheats work and how to create your own cheat. All you have to do is to find or better yet create your own cheat for the game. So even if your skill is not enough to beat the game fairly you won't be frustrated like on the real PS2. Still there are other patches help you cheat on games while playing.
#PCSX2 WIKI DOWNLOAD#
You'll have to discover and download these patches from the Internet.
#PCSX2 WIKI CODE#
Some patches will help you make the broken game playable by messing with its code skipping some of its parts. Patching system is one of the most splendid features of PCSX2.
