Klonoa 2: Lunatea's Veil Decompilation

Matching decompilation project for Klonoa 2: Lunatea's Veil NTSC (SLUS_201.51).

Information relevant to reverse engineering and decompiling the game was retrieved from the following sources:

• Debug symbols from the Klonoa 2 executable from Demo Disc 2.3, extracted using ccc. This includes information about functions, structs, classes, local/global variables, and filenames.
• The C# assembly (Assembly-CSharp.dll) from the Steam release of Klonoa Phantasy Reverie Series. This includes information about functions and structs that were not present in the demo version of the game.

The ee-gcc 2.9-991111-01 compiler (available on decomp.me) seems to produce matching code most of the time, though it is not 100% certain if this was the compiler used to compile the game.

Support the series by purchasing & playing Klonoa Phantasy Reverie Series! :D

Disclaimer

This repository does not contain any game assets, thus a legal copy of the game is required for this decompilation to work. Do not request for these files to be provided.

Building

NOTE: This project is in VERY early stages and may fail to build.

1. Setup environment:
   • Set the SCESDK environment variable to the root of the official PS2 SDK (usually /usr/local/sce). Download links to the SDK will not be provided in this repository.
2. Clone this repository:

   git clone https://github.com/entriphy/kl2_lv_decomp.git
   cd kl2_lv_decomp

3. Build the ELF file:

   cmake -Bbuild
   cd build
   make

4. The resulting ELF file will be named kl2_lv_decomp.elf. You can launch it with PCSX2 using the following command:

   pcsx2 -elf kl2_lv_decomp.elf <disc_image_file>
