Hijack Address Length Type Description Details
$02A7A1 1 byte Miscellaneous Modified by No More Sprite Tile Limits. Highest sprite slot for reserved sprite 2 in for the selected sprite memory index (only if !OldSpriteHeader is not enabled).
$02A826 6 bytes Jump (JML/JSL) Hijacked by Lunar Magic. Main hijack of the Enhanced Sprite Loader. Changes to "JML start_load : NOP #2".
$02A830 4 bytes Jump (JML/JSL) Hijacked by Lunar Magic. Used by Enhanced Sprite Loader to check for additional options when the loaded byte is #$FF.
$02A834 4 bytes Jump (JML/JSL) Modified by Lunar Magic. Jumps to the sprite loader ending.

Not a actual hijack because this section of code in particular is now unused by the $02A830 hijack.
$02A838 4 bytes Jump (JML/JSL) Modified by Lunar Magic. Jumps to the goal tape point extra bit hack (jumps from $02A9D7).

Not a actual hijack because this section of code in particular is now unused by the $02A830 hijack.
$02A846 4 bytes Jump (JML/JSL) Hijacked by Lunar Magic. Used by Enhanced Sprite Loader to check if Sprite Table needs to be adjusted, for allowing more than 84 sprites per level.

If a Sprite Tool hijacks this address, the job for checking for a "page cross" is up to them, for allowing more than 84 sprites.
$02A84C 2 bytes Code Modified by Lunar Magic. Changes branch from "BNE Return02A84B" to "BNE CODE_02A834", which points to JML.
$02A95B 4 bytes Jump (JML/JSL) Hijacked by Lunar Magic. Sets upper bits of Y position for normal sprites.
$02A968 1 byte Opcode Modified by Lunar Magic. A 'RTL' is placed there. The hijack at $02A95B calls $02A960, which then runs though whatever hijack a sprite tool does (or the original game itself) and then it stops here to capture the loaded Y high byte value and corrects out the high bits by the current vertical jump value.
$02A986 2 bytes Code Modified by Lunar Magic (currently has special logic to detect and handle change by Vitor's SA-1 patch).
$02A9D2 5 bytes Jump (JML/JSL) Modified by the Placeable Disco Shell patch.

JML, hijacks the Shells so they spawn rainbow ones if Extra Bit is set to 1.
$02A9D7 3 bytes Jump (JMP/JSR) Hijacked by Lunar Magic. Inserts a special check for copying the extra bits to the goal point, since the Y position bits can't be used anymore as temporary storage.

Note that there was not enough space for putting a long jump, so this will jump to $02A838, which then contains the proper JML to verify to the goal tape point.
$02AA61 4 bytes Jump (JML/JSL) Hijacked by Lunar Magic. Sets upper bits of Y position for cluster sprites.
$02AB54 5 bytes Jump (JML/JSL) Hijacked by Lunar Magic (JML : NOP). Sets upper bits of Y position for boo ring.
$02ABD0 5 bytes Jump (JML/JSL) Hijacked by Lunar Magic (JML : NOP). Sets upper bits of Y position for shooters.
$02ABF3 1 byte Code Modified by Lunar Magic.

Changed from 3F to 7F to fix a bug where the sprite load (or permanently killed) status for sprite indexes 64 to 127 gets carried over to the next level.
$02AC64 4 bytes Jump (JML/JSL) Hijacked by Lunar Magic. Calls the Sprite Cacher/Accelerator while loading a vertical level.
$02ACA4 4 bytes Jump (JML/JSL) Hijacked by Lunar Magic. Calls the Sprite Cacher/Accelerator while loading a horizontal level.
$02AD34 24 bytes Code Modified by Shell-Collectable Coins and Yoshi/Dragon Coins to fix some inconsistencies with the score sprite generation routine.

$02AF37 4 bytes Jump (JML/JSL) Modified by Triple Ball'n Chain patch. Makes use of extra bit for sprite spawn.
$02AF3D 4 bytes Jump (JML/JSL) Hijacked by Lunar Magic. Sets upper bits of Y position for run-once sprites.
$02AF51 2 bytes Opcode Modified by Triple Ball'n Chain patch (Non SA-1 only). Makes use of scratch ram to store sprite number.
$02AF55 4 bytes Jump (JML/JSL) Modified by Triple Ball'n Chain patch (SA-1 only). Makes use of scratch ram to store sprite number.
$02AFA7 4 bytes Jump (JML/JSL) Hijacked by Lunar Magic. Sets upper bits of Y position for run-once sprites.
$02B889 1 byte Opcode Not modified, however is used by Lunar Magic as an RTL for calling routines that end in RTS in bank 2 with stack magic. So don't modify it.
