Just do what I told you to do on the other thread. Don't think it's toodifficult for you.

Copy this into generic.asm:

;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
;; Sprite Generator, by mikeyk
;;
;; Description: This will generate a normal sprite or a custom sprite depending on the
;; first extra bit. Specify the actual sprite that is generated below
;;
;; NOTE: Trying to generate a sprite that doesn't exist will crash your game
;;
;; Uses first extra bit: YES
;; if the first extra bit is set a custom sprite will be generated
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;

SPRITE_TO_GEN = $48 ;only used if first extra bit is clear
CUST_SPRITE_TO_GEN = $20 ;only used if first extra bit is set

;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
; sprite code JSL
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;

Then, add generic.cfg to the spritelist; since it is a generator, its sprite number on the spritelist will be a number from D0 to DF.

When you have runed spritetool, and the sprite is in your hack; go to Lunar Magic, click on the Koopa shell button to go to the sprite editing mode, and press "Insert". In the command, type whatever number you set the sprite to use, and on the extra info space, type 2.

Then, put it on a level and test.

You'll have to modify the sprite itself, then...

Now, open your hack in it (make a backup first, in case something goes wrong) and try to do what is showed on this screenshot:


Then, save the sprite.
This will make the rock not interact with objects; it will fall straight down.
