--------------------
Make a separate folder with all of Sprite Tool's files, folders, ect.
Then I copy my ROM into the folder. I name it "smw.smc" (No quotes)
I look at the sprites.txt, and modify it to use the sprites I want. Like, if I wanted to put in a Missile Bill and a YI Shyguy, I'd put this:
00 missile_bill.cfg
01 yi_shyguy.cfg
The numbers are the number to insert it as. (Don't worry, it won't overwrite original sprites)
The next part is the name of the .cfg file. (The Missile Bill's .cfg file is named "missile_bill.cfg")
Once thats all done, run Sprite Tool. It'll ask you for the ROM. Put "smw.smc" Then it'll ask for the sprite list. Put "sprites.txt" (No quotes for both)
Then wait for it to finish up inserting. Copy your ROM back to its original folder, replacing the old one. (You may want to keep a backup)
Then go into sprite editing mode in Lunar Magic. (The green shell button) Press insert on your keyboard. A window should open. For Command put the sprite number. Screen number should be obvious. XY isn't need, leave it. Extra bit put 2 or 3, depending on if you want to use it. (Open the sprite's .asm file with notepad to see if the sprite uses it or not, and what it does)
BIG FAT NOTE: It WON'T appear correctly in Lunar Magic, Use ExGFX for it to appear correctly in-game.
--------------------
Of course, this assumes you know how to use ExGFX. I also edited a few parts.
Hopefully this will stop the countless questions being asked about Sprite Tool. :/
I'll amend it if anyone points out vital parts I missed.
Can a mod move this if they think it would be better somewhere else? Or trash it if unnecessary. ._.
