Editing Disassembly instructions

{{DISPLAYTITLE:''Pikmin 2'' disassembly instructions}}
The following guide will teach you how to get a disassembler environment with ''Pikmin 2'''s code, complete with the symbol map. Some things to keep in mind:
* The symbol map (i.e. the thing that gives functions, classes, etc. a name) can only be found in a ''Pikmin 2'' demo inside of a multi-game demo disc.
* These instructions apply to that demo. For most purposes, it's good enough, since the code should be very similar to the final game. You can apply this guide to the final version of ''Pikmin 2'', but you won't be able to get the symbol map working without a lot of effort.
* The disassembly is still written in PowerPC assembly language, and we only have access to the names of functions, classes, and so on; even then, some of them might be missing. We don't have access to the names of variables or anything like that.

== Getting the necessary files ==
# Obtain the Multi Game Demo Disc Version 17 (US).
# Add it to Dolphin's game list.
# Right-click it, Properties, Filesystem, go down to <code>zz_Pikmin2_game.tgc</code>, right-click it, Extract File..., and extract it somewhere.
# Add the ''Pikmin 2'' demo you've extracted to Dolphin's game list.
#* If your version of Dolphin can't read .tgc files, download tgctogcm and run the .tgc file through it, in order to get a plain old .gcm file.
# Right-click the ''Pikmin 2'' demo in Dolphin's game list, Properties, Filesystem:
## Right-click Disc at the top of the tree, Extract DOL..., and extract it somewhere.
## Find <code>pikmin2UP.MAP</code>, right-click it, Extract File..., and extract it somewhere.

== Setting up a disassembly environment ==
=== Basics ===
# Install [https://ghidra-sre.org Ghidra] (and maybe familiarize yourself with how it works).
# Go to the [https://github.com/aldelaro5/ghidra-gekko-broadway-lang Ghidra Gekko/Brodway language project], and follow the instructions to install it on Ghidra.
# Go to the [https://github.com/Cuyler36/Ghidra-GameCube-Loader Ghidra GameCube loader project], and follow the instructions to install it on Ghidra.
# In Ghidra, create a project for ''Pikmin 2'', and add the .dol file you extracted to the project. The type should be detected automatically, but you should select GameCube game.
# When asked if you want to include a symbol map, choose yes, and pick the .MAP file you extracted.
# Drag the .dol file to the CodeBrowser tool. When prompted to analyze the project, press Yes, and go with the defaults.

=== Details ===
# In the disassembly pane, select all with Ctrl+A.
# Right-click, Set Register Values...
# Set r2 to <code>8051e2a0</code>, and r13 to <code>8051c5c0</code>.
#* The game uses these registers a lot to load data. These values can be obtained by playing the demo in Dolphin with debug mode, pausing emulation, and examining the value of the registers, since they're always the same.
