I decided to look into the Ejected Casings stuff to see how feasible it'd be to add more since the game has two for the Assault Rifle ammo type (KF7 uses Rifle Casing - GcartrifleZ, AR33 & Sniper Rifle use Rifle Casing Alt - GcartblueZ), here is what I've discovered through hex editing and following the RAM addresses:


EJECTED CASINGS TABLE:
Hex Address in 21990: 116DC - 11704
RAM Address: 8003246C - 80032494

RAM for Slot
RAM for File Name

Immediately after the table is the Gun Block Details starting with Gun 00.

Slot 00: Pistol Casing
Hex Address in 21990: 116DC
RAM Address: 8003246C

Slot 01: Rifle Casing
Hex Address in 21990: 116E4
RAM Address: 80032474

Slot 02: Rifle Casing Alt
Hex Address in 21990: 116EC
RAM Address: 8003247C

Slot 03: Shotgun Shell
Hex Address in 21990: 116F4
RAM Address: 80032484

Slot 04: None
Hex Address in 21990: 116FC
RAM Address: 8003248C


Swapping the slots is the same as swapping the file names, Ex:
Slot 00 8003CB60 80053760 -> 8003CB80 80053760
Slot 01 8003CB80 8005376C -> 8003CBC0 8005376C
Slot 02 8003CBA0 80053778 -> 8003CB60 80053778
Slot 03 8003CBC0 80053784 -> 8003CBA0 80053784
This results in every weapon set to "8003CB60 Pistol Casing" jumping to Slot 02 to use Rifle Casing Alt rather than still using Slot 00, so the specific RAM address for the slots are what is being searched for, if not found then the game freezes. Custom slots work, just the usual stuff of needing to duplicate the data somewhere else and manually hex editing the desired weapon's Ejected Casings setting to point to the new spot since the editor uses a drop down list based on the original table.
If there is a duplicate slot, the first one & it's accompanying file name is used.

Using "00000000" as the slot acts as a cutoff, even if there are additional slots used afterwards.
Continuing the previous ex:
Slot 00 8003CB60 80053760 -> 8003CB80 80053760
Slot 01 8003CB80 8005376C -> 8003CBC0 8005376C
Slot 02 8003CBA0 80053778 -> 00000000 80053778
Slot 03 8003CBC0 80053784 -> 8003CBA0 80053784
This results in only the weapons set to "8003CB80 Rifle Casing" and "8003CBC0 Shotgun Shell" continuing to eject cases, Pistol & Rifle Casings in this ex. Everything else is skipped because they're found after the slot intended for None.
Because of this, if you don't have any of the five slots set to "00000000" then the game freezes from trying to load garbage data as additional slots. Because the game skips whatever slots are remaining, you don't have to worry about missing RAM addresses but it's much easier and safer to just use the Editor to set weapons to "00000000 None"


EJECTED CASINGS FILE NAMES:
Hex Address in 21990: 329D0 - 32A00
RAM Address: 80053760 - 80053790

GcartridgeZ
Hex Address in 21990: 329D0
RAM Address: 80053760

GcartrifleZ
Hex Address in 21990: 329DC
RAM Address: 8005376C

GcartblueZ
Hex Address in 21990: 329E8
RAM Address: 80053778

GcartshellZ
Hex Address in 21990: 329F4
RAM Address: 80053784

(empty name)
Hex Address in 21990: 32A00
RAM Address: 80053790

(empty name) is not a valid file name, the game works simply because it's not actually spawning anything when a weapon's Ejected Casing is set to "00000000 None"
Renaming existing Gcart_Z files works as expected, changing the file name to point to a new file works as expected where the game only freezes when the new model is not designed to be an Ejected Casing model.



EJECTED CASINGS STUFF:
Hex Address in 21990: 1BDD0 - 1BE50
RAM Address: 8003CB60 - 8003CBE0

GcartridgeZ
Hex Address in 21990: 1BDD0
RAM Address: 8003CB60

GcartrifleZ
Hex Address in 21990: 1BDF0
RAM Address: 8003CB80

GcartblueZ
Hex Address in 21990: 1BE10
RAM Address: 8003CBA0

GcartshellZ
Hex Address in 21990: 1BE30
RAM Address: 8003CBC0

Located with other stuff, has at least one section that's a float and I think "8003C728" is some kind of behavior because the surrounding groups use "8003C714" instead along with some other values. Could not immediately notice a difference when changing the float.



Using the Footsteps Patch's Memory Peek/Poke feature:

All of this can be messed with but you have to reload the level for the changes to take effect. The exception is editing the Gun Block Details to change what Ejected Casing a weapon looks for because that's reloaded every time you switch weapons like the file name for the model (this is how Mario Characters has recolored hands for the Play as Cheats)


What I could not figure out was relocating the table for extensions.
458E2-458E5 in the ROM has a 80032464 but it is NOT the table. Don't know what it changes but it ain't that.

It is possible that it might be like some stuff where the RAM address is split so 8003 (or maybe even 8004 since sometimes it's higher like that) and then 2464 in a different spot, which I don't know how to figure that out. If someone else could find it, that'd be great. Theoretically that should be the only hurdle for extending the system, the Editor does it's usual thing of failing to load a chosen option from the dropdown menu but otherwise leaves it alone until you change it.

On a slightly different note, Perfect Dark uses Rifle Casing Alt with the file name still being named GcartblueZ while GcartrifleZ got replaced with a different ammo type. You'd expect it to be the other way around but no.

It is possible to add exactly one extra slot for the Ejected Casings Table by overwriting the first 8 bytes of Gun 00's Block Details (Muzzle Flash Extension & In-game Pos 1) specifically because "00000000 None" doesn't spawn anything which means it ignores the accompanying file name. This matters because the Editor will automatically converts floats when the number is neglible, which in the case of RAM addresses means they get turned into 80000000 because when converted to floats they all equal "-0.0000000000" regardless of if they're 8000XXXX, 8003XXXX, 8004XXXX, 8005XXXX, etc
Now if the RAM address is 7FXXXXXX then the corresponding float is a massive number that does not get converted by the editor. However, this is outside of the 21990 file and found in the actual ROM which makes it very hard to create free space for.
If the Editor didn't automatically convert the numbers, then you would have a large section of Gun 00's Block Details to overwrite since it's not a useable weapon, but I'm sure changing that would break other things in the Editor so it's not a suggestion. Just an observation that in regards to the game itself, it's safe to overwrite.



EDIT- September 17, 2026:

For some reason using a 7FXXXXXX RAM address only works on Emulator, on Console the new casing model doesn't appear but otherwise the game functions fine. It's not the model itself, and using it inside the normal range still results in nothing appearing on Console so it's specifically something about the RAM address even though by all accounts it should've worked perfectly. So, sadly, the Ejected Casings Table has to be moved to another spot within the 21990 file in order to have more slots using RAM addresses within the 21990 file.
On a more positive note, documented some stuff regarding the Multi Pickup setting as that was how I found a spot within the Rom to test out using a 7FXXXXXX RAM address.

MULTI PICKUP TABLE:
Hex Address in 21990: 3689C - 3691C
RAM Address: 8005762C - 800576AC

36920 is set to "00000000" but it does not end the table like various other tables, or at least that's my assumption since I don't know what is immediately after the table. If it does end the table, something else tells the game to stop assigning Pickup models to weapons because when 36920 is changed, Gun 20 and so on will continue to have nothing assigned to them rather than crashing from invalid RAM addresses.

Hex Address in Rom: CFE8C

None:
Hex Address in Rom: CFE90
RAM Address: 7F09B360

None uses "03E00008 00601025" instead of the normal format.
Game does not like it when this gets moved around, but the regular slots can be relocated to inside the 21990 File allowing for 0xD8 of free space within the Rom.

None will overrule the Item Bitflags to have a character hold the weapon and instead will have them stand like they don't have a weapon rather than simply holding their arms outwards. If desired, make a custom pickup model that's invisible/tiny as that's just typical custom model stuff.

Custom addresses work so you can move the whole list (besides None) to a spot in the 21990 file to free up 0xD8 of space inside the Rom, allowing for a rare space of usable RAM that starts with 7FXXXXXX which is only important for instances where the address is being stored in a spot it technically shouldn't be, like the Gun Block Details for Gun 00 to extend the Ejected Casings Table. As previously mentioned, using this to add more Ejected Casing slots did not work as expected, so it's possible that other such uses of this area might not work as intended. Still worth documenting though.
