Virtual Pro-Wrestling 2

This is a decompilation project for AKI Corporation's Virtual Pro-Wrestling 2 (バーチャル・プロレス2 〜王道継承〜), a Nintendo 64 wrestling game.

Like most other N64 decomp projects, this is very much a work in progress.

Also like other N64 decomp projects, you will need a ROM of the game to extract the necessary assets, as they are not included in this repository.

Introduction

Some crazy person spends over a decade or two of his life trying to hack a video game.

This repository has two main purposes:

1. Document game information for any interested hackers.
2. Serve as a base for future hacks requiring non-trivial changes.

Requirements

• a Linux environment (native, virtual machine, WSL2 on Windows 10)
• GNU make (and probably the other stuff from build-essential if your distro has that)
• binutils-mips-linux-gnu
• gcc-mips-linux-gnu
• gcc-multilib
• Python 3.x
• an unmodified Virtual Pro-Wrestling 2 ROM in Z64 format, legally obtained

While qemu-irix was previously listed here, it is currently not used. It may or may not be used in the future.

This has only been tested on Linux using a VM, and WSL2 on Windows 10.

An unmodified VPW2 ROM in Z64 format should have the SHA-1 hash 82dd25a044689eab57ab362fe10c0da6388c217a.

If you need help verifying your ROM, use the VPW2 ROM ID program.

Setup

Step 1: Set up prerequisites

For Debian (and Debian-based systems), this should handle most of it:

sudo apt-get update
sudo apt-get install binutils-mips-linux-gnu gcc-mips-linux-gnu gcc-multilib make git

If you don't already have host/native development tools set up, you'll also need 'build-essential':

sudo apt-get install build-essential

Step 2: Clone and set up the git repository

git clone --recurse-submodules https://github.com/AKI-Club/vpw2

If you are manually cloning the repository (i.e. without --recurse-submodules), you need to initialize the submodules as well.

Step 3: Perform setup

Place an unmodified copy of your existing ROM inside the root of this repository with the name baserom.z64, then run the following command:

make setup

This will build the necessary tools, extract the binary files from the ROM, and extract the data from the file table (this will take a while).

Further tasks (such as converting the file table data to human-editable assets) are still to-do.

Building

Run make in the main directory.

Further Steps

todo: the next steps (a.k.a. draw disassemble the rest of the fucking owl game)
