Glossary

This page serves as a glossary of commonly used Wii homebrew terms. Think of it as a mini dictionary for words you'll hear a lot while reading through our wiki. It was started to help newcomers to the homebrew scene better understand our jargon.

A

AES

Stands for Advanced Encryption Standard. It is used for encryption on the Wii.

AES-CBC-128

The CBC (Cipher Block Chaining) mode of AES with a 128 bit key, that is used on the Wii.

B

Backup

A copy of a game that has been dumped from the original disc in case it should become unusable due to wear/damage. Since the same method is used to pirate games, they are not discussed or encouraged here.

Banner

BASIC

An old programming language very few apps are programmed in via a BASIC to C converter and compiler.

Banner Brick

An error preventing the Wii's channel menu from displaying. It occurs when a WAD is installed with a banner that uses the wrong image sizes.

See also: System Menu, Brick, Semi-Brick.

Bit

Stands for Binary Digit; it represents smallest amount of digital data possible. It is either a 0 or a 1.

Binary

A term used to describe the base 2 number system when used with electronics. As slang, it also refers to an executable file.

boot1

boot2

BootMii

Team Twiizers' latest project. It is basically a replacement for boot2 that loads and runs code before the system menu.

See also: System Menu.

Brick

A console that is no longer working due to damaged hardware or an error with the internal software/filesystem. Usually the fault of the owner. Sometimes recoverable through special means.

Broadway

The codename for the primary PowerPC processor.

Bushing

A predominant member of Team Twiizers.

Byte

Eight bits, on all modern processors; the smallest number of bits that can be sent to/from memory at a time.

C

C

A language homebrew developers program in.

C++

An object oriented language homebrew developers program in. Like its name suggests, C++ is essentially a step up from C.

Channel

cIOS

A customized/hacked version of an IOS.

cMIOS

A customized/hacked version of an MIOS.

Code Dump

Basically a crash that displays code (or seemingly random numbers and letters to those that dont know how to read it) on the screen. Wii Homebrew code dumps will generally read "Exception DSI Occurred" or "Exception ISI Ocurred".

Codemii

The development blog of the Homebrew Browser.

See also: Homebrew Browser.

Compile

To source code into a format that can be executed/launched.

See also: Source, Binary.

D

Dev

See: "Homebrew Developer".

DevkitPro

The SDK all homebrew developers use to create apps.

DOL

Most common executable file format for Wii and Gamecube homebrew.

See also: Binary, Homebrew.

Dump

E

Electronic Gate

A device which takes electronic signals (inputs) and outputs a signal based on the status of its inputs. Some examples of electronic gates are AND, OR, NOT, NAND, NOR, and XOR.

ELF

An executable file format used for some Wii homebrew.

See also: Binary, Homebrew.

Emulator

Software that simulates a specific hardware environment (such as an old gaming console) so that programs designed for that hardware (such as old games) can be run on different hardware (such as a PC or different game console) which those programs were never designed to run on.

Encryption

Simply put, encryption is hiding information. Like replacing A with 1, B with 2, C with 3, etc. in order to make important information harder to be read. Real encryption, however, is typically much more complex than that, involving math operations on huge secret numbers that would take millions of years to calculate.

F

Fakesign

Homebrew that exploits a bug in the Wii's signature handling to bypass the digital signature. This exploit was fixed in IOSes distributed with system menu version 3.2.

Flash

A type of data storage used internally by the Wii.

See also: NAND.

Firmware

Fixed low-level code written directly into a programmable chip. The Wii's system menu software is NOT firmware, despite what some misguided people may think.

G

GPU

Graphics Processing Unit, responsible for rendering everything you see on screen.

See also: Hollywood.

H

Hackmii

The development blog of Team Twiizers.

Hexadecimal (Hex)

A term used to describe the base 16 number system, in which each digit represents four bits. After the digits 0-9, the letters A-F are used to represent the values 10-15. Hexadecimal is the preferred format for displaying binary data, as it is easy to mentally convert to/from binary and uses only 2 characters per byte.

Hollywood

The Wii's integrated graphics chip, manufactured by ATi.

See also: GPU.

Homebrew

Unofficial software created for a platform by its users, without the involvement of the vendor. While some vendors support or ignore homebrew, most video game companies (including Nintendo) disapprove and make efforts to prevent it, due to the potential for unofficial software to brick the system or be used for piracy.

Homebrew applications

Generally refers to an application run on the Wii via the Homebrew Channel.

Homebrew Browser

A homebrew application that lets users download other homebrew applications directly to their SD card without the need to use a PC.

Homebrew Channel

A channel created by Team Twiizers that allows you to run exectutable .dol and .elf files.

Homebrew Developer

Refers to someone who develops Wii homebrew applications.

I

IOS

Input/Output System. These programs run on the Starlet coprocessor and control access to Wii hardware and security.

See also: Starlet.

IRC

Internet Relay Chat; that is, realtime text-based chat over the Internet.

Infectus

A modchip that can read and write data to and from the Wii's internal NAND. Very useful for hacking.

See also: Modchip.

L

Library

Generally given the extension *.a, a library is a compilation of source code that may be linked into a program.

M

Marcan

A predominant member of Team Twiizers.

MIOS

The IOS used in Gamecube mode, responsible for locking out all new hardware to make the system functionally identical to a Gamecube.

Modchip

A device containing simple firmware that is usually soldered or clipped onto a circuit board typically for the purpose of altering or circumventing the normal functions of a device. In a game console, a modchip almost always serves to enable the playing of backup and/or pirated copies of games.

N

NAND

Typically refers to the Wii's internal storage, which uses a NAND-based flash chip. The term actually stands for Not-AND; an electronic gate whose output is high only when all inputs are low.

See also: Flash.

P

Partial Brick

See "Semi-Brick".

PCB

Printed Circuit Board. The Wii has a few of these, most notably the mainboard containing all the crucial parts and the game disc drive's control board where modchips are typically installed.

PPC

PowerPC; Power Performance Computing. The processing architecture of the Gamecube and Wii consoles. Also used in the XBOX 360 and Playstation 3.

R

RSA

An encryption/digital signature algorithm used by the Wii. When implemented correctly it is too strong to be broken with modern technology. The acronym is made from the names of its inventors.

S

SD Card

A common type of memory card, used by the Wii, digital cameras, music players, etc. Stands for Secure Digital.

SDHC

Stands for Secure Digital High Capacity Card. A type of SD card with a higher storage capacity than normal SD cards.

SDK

Stands for Standard Development Kit; An SDK is a group of libraries that allow a programmer to access the primary features of a platform.

Semi-Brick

A console that is no longer working normally but still has some useful functionality which may be used to restore full functionality. Usually, a semi-brick is the fault of the owner.

Soldering

The process of attaching two or more metal components by melting additional metal directly onto them. This process is used to add components onto circuit boards.

Source

The code for a program before it is compiled into a binary executable.

Stack

The memory of a program. As one declares pointers and integers, the computer sets aside memory for each. That memory then "stacks" itself on the last declaration. Think about stacking up building blocks and each block is a piece of memory.

Stack Overflow

Simply put: Bad coding that makes the stack crash. There are a number of ways to do this. It can lead to an exploit in some cases.

Starlet

The unofficial name for the ARM coprocessor located in the Hollywood, which is responsible for the peripheral access and security control.

See also: Hollywood.

Svpe

A very talented coder. He modified the libfat library which allows for support of SD and SDHC cards as well as USB devices in Wii homebrew. He also wrote a version of DVDX that installs on firmware 3.4

System Menu

TMD

See "Title metadata".

Title metadata

A format used for storing metadata about a title and its installed contents, including which contents they consist of and their SHA1 hashes.

Title

A title is a Wii game on a disc, a Wii channel or a virtual console game. A title is identified by a unique title ID, an 8 byte (4 character) long code used for title identification.

Virtual Console

A phrase invented by Nintendo so that they didn't have to use the word "emulator".

W

WAD

An archive format channels are contained in.

Warez

Refers to any pirated digital content.

WiiWare
