SMW Hacking YI Hacking General ROM Hacking SMW Central
SMW Hack Terms
Vanilla From and/or related to the original SMW (e.g. vanilla graphics, vanilla samples, etc.).
Chocolate Unrelated to the original SMW. In other words, custom.
Kaizo Referring to very difficult hacks which follow a specific design philosophy and a specific type of level design. Often, this means that the levels do not give a choice to the player on how to play them, but rather force specific strategies. Kaizo: Light is supposed to be beatable without tools, Kaizo: Hard is supposed to require tool usage.
Pit A subset of kaizo that is intended to only be beatable with heavy tool usage.
Troll A particular genre of hacks that mess with the player's expectations. Further info here.
Base ROM A patch that already contains certain resources (e.g. graphics, music, sprites, etc.), but no levels, intended to be used as a base for a hack or level.

Emulator A program that simulates an SNES, or any other console, and allows you to run ROM images meant for it.
TAS (Tool-Assisted Speedrun) A speedrun of a game or hack that is done using precise input commands frame-by-frame, allowing for perfect precision.
ROM (Read-Only Memory) In the context that concerns us, a ROM is a file containing all the data for a game. Note that these are illegal to distribute if copyrighted. More generally, ROM data is static data that can be read by the game but not altered.
RAM (Random Access Memory) A section of memory that can be read from or written to, used to track all of the dynamic aspects of a game (player position, coin count, current level, etc.).
ARAM (Audio Random Access Memory) A subset of RAM that specifically contains data relating to audio, such as loaded samples and echo.
OAM (Object Attribute Memory) A 544 byte region in memory that controls various sprite tile properties such as position, appearance and palette.
MSU-1 (Media Streaming Unit 1) A chip that allows the use of MP3-quality audio on the SNES.
SA-1 A chip that is more than twice as fast as the SNES's standalone processor.
Super FX A chip that allows the SNES to render polygons.
DMA (Direct Memory Access) A feature of the SNES that allows for both rapid data transfer and modification of visual properties.
HDMA (Horizontal (Blank) Direct Memory Access) Allows the SNES to change display options mid-screen, allowing things like wavy effects, gradients, or parallax.
Mode The SNES has multiple video modes, which change things like how many layers there are and how many colors are allowed on each layer. There's also mode 7, which is special because it allows things like rotation and scaling effects; it is used in most boss battles in vanilla SMW. SMW otherwise uses Mode 1.
Sprite One of a set of individually positionable entities on the screen. In SMW, these include enemies, powerups, Yoshi, and the player.
Object A collection of tiles in a fixed grid. In SMW, an "object" can generally refer to a single item built from several such tiles, such as a pipe or a slope.
Palette The set of colours that can be applied to a certain element on screen. In SMW, the first 128 colors may be used by objects, the last 128 colors by sprites.

GFX (Graphics) Usually references to graphics that are already in SMW.
ExGFX (Extended/Extra Graphics) Refers to custom graphics.
Layer 1 This is the layer which contains most of the main foreground objects in SMW.
Layer 2 This refers to a layer of tiles behind the main level. In most cases, this is just a background image, but it can also be interactive in some levels, in which case it can scroll separately from the main foreground.
Layer 3 This is the layer that the status bar is on. It's more limited in colour than layers 1/2. It is usually only used for the layer that the status bar is on, but can also be used for a simpler background when layer 2 is in use already.
