Can you drown me with your ripping knowledge?

[Reko]

I want to make a tutorial for starters (like me) where they can find all the things they need to know about ripping, just like:

• A ripping dictionary with the basic words, terms, names... (Ex: Tile, texture, model, hex editor, ROM...) with their respective definitions.
  
• A file extension list (Ex: .nclr - Color pallete, usually found in DS games. / .pkg - PS3's file extension, where all the other files are locked...).
  
• A tool ripping list (Ex: Tilemolester - Sprite editor, you can open .gba files, see the sprite sheets of the game and edit them as you like. / CristalTile2 - Sprite editor, you can open .gba and .nds files, just as tiles and palettes and edit them as you like...).
  
• An emulator list, though I don't think they're really necessary if you're gonna hack the game's ROM (Ex: DeSmuME - DS emulator. / VBA - GBA emulator...).
  

So, if you know something about this four points, please, tell me. It doesn't matter if it's the most stupid thing, like the definition of tile or the most complicated, like using a ripping tool (in this case, you don't need to give a tutorial of such tool, just what use is for); just tell.

PS: I'm particularly interested in GBA, DS and PS3 (2D games) sprites and the original idea was doing a tutorial about ripping such ones, but I decided to do a tutorial of general and basic things first.

If I got enough information, I'll open a new thread with the tutorial, guide or whatever you want to call it but you'll have to help if you want that thing possible.
