deadlocked-patch-loader

I am taking advantage of the patch.bin file that Ratchet: Deadlocked uses. I've known how to use the patch file for a while now, and i decided to take my knowledge and learning farthur. I am using the patch.bin file to hook into the kernel of te PS2, then it copies the needed Deadlocked-Chaos codes into EE memory and runs via a second hook.

Why not just use a cheat device? This is more fun. And this way I can just share a save file with an edited patch.bin file for others to play right away.

Current Progress

1. Current code in Codes/main.c is Infinite Health/Moon Jump. It works in Single Player only.

How To Use

0. Obtain a copy of the mod. Whether you compile it or get a shared save, you're choice.
1. Once the file/save is in the correct spot, start the game.
2. Once loaded, Go to "Mulitplayer". The mod will automatically load.
3. Once on the multiplayer menu, Press Circle to Enable/Disable the mod.
4. Once Enabled, Exit by pressing triangle and then choose single player and choose a new save (or a current save...?).
5. Enjoy the mod!

Build with docker

Clone Repo:

git clone https://github.com/Metroynome/deadlocked-patch-loader.git
cd deadlocked-patch-loader

Get PS2SDK via docker:

docker pull ps2dev/ps2dev:v1.2.0
docker run -it --rm -v "$PWD\:/src" ps2dev/ps2dev:v1.2.0
cd src
./docker-init.sh

Make it:

make clean && make

When building, it also creates a codes.pnach cheat file in Codes/. This is so you can test the mod with PCSX2, without the need of loading into the Multiplayer Menu.

How it Compiles Currently:

1. Compile Codes/ directory This holds all the Chaos-Mod codes/timers
   1. Compile codes.bin and codes.elf (stripped .elf)
   2. Convert codes.elf to codes.s
   3. copy codes.s to /../Kernel
2. Compile Kernel/ directory This is where the code can hook into the kernel via the patch.bin
   1. Compile kernel.bin and kernel.elfwith an added codes.s added to the EE_OBJ line.
   2. copy kernel.bin to /../bin
3. Compile bin/ directory This is where the new patch.bin file is created.
   1. Copy patch-template.bin from template/ to bin/ as patch.bin
   2. Write kernel.bin file into patch.bin at offset 0x100, or 256 bytes
