GB/GBC Sprite Ripping?

[daemoth]

can someone explain to me how to use YYCHR to rip all sprites from zelda LA/OOS/OOA
currently it brings up a ton of random pixels

First, you will need to get the palettes ( the colors used by the sprites). Play the game until the sprites are displayed, and make a save states. Then with YYCHR, do Palette/Load Save state. You can then select the palette in the bottom right.
Secondly,  in YYCHR, dont forget to set the format to "2BPP GB". 
Then, you scroll down until you see something you recognize,take the correct, adjust with the arrows on the side until the image is clear, and youre done
This is how i do with Snes ( except for the format part, of course), im guessing its the same.
