 Palette instructions are a mix of colours (which are positive values) and ASM instructions (negative values). Colours are written to successive positions in CGRAM starting from initial colour index. ASM instructions can modify the colour index between listed colour values, and the instruction $C595 is used to terminate the palette instruction list.

-The properties are as follows:
-h  Detect collisions with projectiles
-h  Don't die on contact
-h  Disable collisions with Samus
-h  Low priority (drawn under enemies/Samus/projectiles)
-The special instructions for enemy projectiles have the format:
-   ______ Spritemap timer
-  |     _ Pointer to spritemap
-  |    |
-  tttt ssss
-The spritemap timer is how many frames to wait until the next instruction in the instruction list is proceeded to. Within the spritemap, the tile numbers added to the base tile number set when the enemy projectile was spawned (so the projectile can access enemy graphics).
-==== Animated Tiles Objects ====
-Animated tiles objects are objects that modify tile graphics in real-time. They exist in bank $87 and are loaded with a room from an FX header.

-==== HDMA Objects ====
-HDMA objects exist in bank $88 and are typically loaded with a room as part of FX or spawned by power bombs / x-ray.
-HDMA object header format:
-   _______ HDMA options

-==== Palette FX Objects ====
-Palette FX objects are objects that modify palette data in real-time. They exist in bank $8D and are loaded with a room from an FX header.
-Palette FX object header format:
-   ______ Initialisation ASM pointer
-  |     _ Instruction list pointer

-The palette timer is how many frames to wait until the next instruction in the instruction list is proceeded to.
-The ASM instructions are usually used for setting the initial colour index, which is an index into CGRAM equal to (p * 10h + c) * 2 where p is the palette number and c is the colour index within the palette.
-Palette instructions are a mix of colours (which are positive values) and ASM instructions (negative values). Colours are written to successive positions in CGRAM starting from initial colour index. ASM instructions can modify the colour index between listed colour values, and the instruction $C595 is used to terminate the palette instruction list.
