MemoryIO.Pcsx2

An implemention of MemoryIO specifically for the PCSX2 emulator. Designed along-side MemoryIO to provide an easy-to-use, cross platform PCSX2 memory manipulation experience.

Usage

Pcsx2MemoryIO automatically attempts to detect and attach to a PCSX2 process. Because different PS2 games use different string encodings, it is recommended that you provide an Encoding for Pcsx2MemoryIO to use, otherwise it will default to UTF8.
For example, .hack//Fragment uses "Shift-JIS" encoding.

Pcsx2MemoryIO exposes two bool properties to check the state of the process such, IsPcsx2Running and IsAttached.
Calling Update() will attempt to find and attach to a PCSX2 process if not already attached.

EEmem BaseAddress

Pcsx2MemoryIO automatically finds the BaseAddress of EEmem based on whether the process is running in 64bit or 32bit mode. This allows users to simply use the address without worrying about where the EEmem was initialized.
If you have used Cheat Engine on PCSX2 1.6.0 you might have found a value at address 0x20C461DA. With Pcsx2MemoryIO, you would just ignore the first 2 and use 0x00C461DA.
IMemoryIO methods are overloaded with methods that take an int address for convenience as the PS2 architecture is 32bit. Pcsx2MemoryIO does expose the BaseAddress of EEmem as an IntPtr in case users want to access it.

Example

internal struct PlayerStruct
{
    public int NamePointer;
    public short Level;
    public short EXP;
    public int GP;
}

const int playerAddress = 0xC461DA;
const int partyPointersAddress = 0x8B9390;

Pcsx2MemoryIO memoryIO = new(Encoding.GetEncoding("Shift-JIS"));

if (memoryIO.IsAttached)
{
    PlayerStruct player = memoryIO.Read<PlayerStruct>(playerAddress);
    player.GP = 999999;
    player.Level = 99;
    memoryIO.Write(playerAddress, player);

    int[] partyPointers = memoryIO.ReadArray<int>(partyPointersAddress, 3);
    PlayerStruct party3 = memoryIO.Read<PlayerStruct>(partyPointers[2]);
    memoryIO.WriteString(party3.NamePointer, "Kite");
}
