Knights of Justice warp hack

[ladyabaxa]

Why yes I have been trying to glitch sprites so that they appear in areas they aren't supposed to. I want to know if anything interesting pops up. I'm using the Zug because it's semi-reliable in not wanting to crash. However, I have to keep infinite life enabled because if Arthur dies the emulator will crash. It is interesting in that the Viper sprite is loaded into memory as soon as you enter his room. That's good because once you close the menu and start fighting the giant snake you can't re-open it to try another warp until Viper is dead.

How did I do this? That's simple. I warped to the screen with the creature I wanted to transplant then warped to the Swamp of Zagar. The first critter's sprite will, at times, overwrite the second one's. I would try taking the Zug someplace else but the way it works is that it spawns offscreen and charges Arthur. At the moment it spawns the game goes into combat mode (a special script is running) until the Zug has been offscreen for a few seconds on the opposite side where it then despawns.

It's probably just as well. The Zug is invincible. Believe me, I've tried to kill that thing!

This will work with any screen up to memory position 255. Trying to warp to a position any higher doesn't work for some reason. This means I can't take any boss creature to any of those screens. I was hoping I could drag the ogre into the last room in Blackroot Keep but it simply refuses to work. That room is item 258 in the list. It's already enough of a pain getting multiple warp codes working in unison. Oh well I guess there's not much I can do about it.

Click the LJ cut if you want a list of all warp memory positions I've located.

Warp codes

Warping is unpredictable as the exact coordinates can change depending upon where you are standing when you activate the warp. You can warp into walls, trees, rocks, or on top of areas with no walking path off. In addition disabling the code, entering the map screen, then exiting frequently results in warping into a wall in a fortress. To clear the address in memory disable the code then walk from one area to another. You can also use the Magic Map in the overworld as intended without a warp code getting in the way.

Things to keep in mind:

Having allies while using warp codes can cause Arthur to become stuck. If you warp into a wall he and the other knights will be overlapped which will NOT be corrected if you then warp to another screen. This can be corrected by actually using the magic Map as designed (i.e. keep the code on but warp via the map to a valid destination).

Just be warned that if you are exiting the Dark Forest or any area in that region there is a semi-permanent lock-out from using the map.  Returning to Camelot will not correct this issue.  The only remedy is to progress through the game's events in the land of the dead and enter the Stone Gardens.

Warping onto a screen with enemies can cause Arthur to become stuck if he cannot move. To prevent this always warp by entering Inventory, NOT the map screen and do not close the main menu until you are certain your position is valid to move from. Once the menu is closed if there are enemies close by the game sends you into Combat Mode and the menu locks. As long as the menu isn't closed out after warping you can re-enter Inventory and warp out.  Technically the password and status screens work too but have a longer transition time each.  It's almost always faster to use the Inventory screen.

Warping into a living warlord's room is extremely dangerous as the room may not load properly and Arthur is prone to being stuck and unable to defend himself. The warlord may also spawn invisible "phantom" clones and have an accelerated rate of attack. Because all Warlord rooms with an active boss lock down the menu as part of the room loading there is no escape if you exit the menu and the boss can't reach you. If you warp into Warlord Slasher's room you must quickly hit multiple directions on the D-Pad or the controls will remain locked out and you will only be able to pause the game. This is because of a loading script that transitions Slasher from a normal human size into the giant which you fight.

If you do warp in and kill Morgana the game does not end early. Doing so actually triggers a series of glitches. The game thinks you are picking up whatever Key you're supposed to be getting based on your Key count and Arthur will say you need that Knight in your party but he is then allowed to pick up the key, Merlin appears to congratulate Breeze, Arthur returns to Camelot, and the game thinks you've killed another Warlord so it advances the plot.

However, if the Key would be a non-boss key (such as Tone's) the game might hang once you return to Camelot before Merlin would appear to give you the next clue. Sometimes it only appears as a crash but the game is just waiting for the player to close invisible dialogue boxes. Hitting A will resolve this issue. It is not a problem unique to this case as any time you change screens with an open dialogue box the same thing will happen.

If the warp code is active during Merlin's Vilor dream explanation after showing the backdoor to the fortress Merlin and Arthur will be warped to Morganna's room to finish the conversation. This can result in her dragon form having a case of scrambled graphics.

The Key count can also be glitchy. I first did this fight without picking up the Keys for Trunk, Zeke, or Lance. On killing Morgana I got the speech about needing Lance - skipping Trunk and Zeke completely! On warping immediately back and killing her again the game thought I had all 12 Keys and started the ending sequence.

Another skip happened again on another test. ALL the non-boss keys were skipped along with Lance's.

7E1155 :mod number as listed below

:00 [000] - Camelot

:01 [001] - map screen

:08 [008] - warp to Stadium

:09 [009] - debug room? By disabling BG Layer 1 Arthur becomes visible. By porting in from the southwestern corner of Camelot Field can move around here. There are invisible walls and warps all over the place. Most of the warps crash.
-There is quite a lot of text still in the ROM pointing to a Debug room's existence. That text will be in a seperate post. Each warp *seems* to have a specific time in the game when it won't crash.

------------------------------------------------

:0a [010] - debug room 2 (see notes above under debug room 1)

:0b [011] - Welton forest where the pixies attack

:1a [026] - game crashes!

:1b [027] - Erek's Cave

:1c [028] - Ogre's Tree
This can spawn multiple ogres.  All ogres will perform the same action simultaneously.  They are limited to moving straight up and down.  If one clone goes offscreen at the bottom scrolling the screen that far down can cause lines of scrambled junk to appear.  Once one dies it drops the staff piece at that spot.  If there are any living clones they must also be killed before the piece can be collected.

Be careful with taking the Ogre to other screens if you need the staff piece.  If the piece is in an unreachable location it will disappear as soon as you leave the screen and the ogre will still be dead.  This can cause a potentially unwinnable situation.

ad: [173] - Dark Forest, aforementioned cliff

Depending on where you warped from (say just below the leftmost bridge in front of Camelot) you can become stuck on a little outcropping. Walking south activates a fade that doesn't do anything else.

:f8 [248] - small room in Blackroot

:f9 [249] - trapdoor room in Blackroot

------------------------------------------------

fa: [250] - Blackroot

fb: [251] - another room of Blackroot

fc: [252] - empty room in Blackroot

fd: [253] - Blackroot

fe: [254] - Blackroot

ff: [255] - room before staff piece in Blackroot

------------------------------------------------

First perform the FF warp then use the 01 warp in combo or walk to ambush room 1 then proceed with the final destination as listed below.


ff: + 01: [256] - ambush room 1 in Blackroot

ff: + 02: [257] - ambush room 2 in Blackroot

ff: + 03: [258] - Zeke's Key

ff: + 04: [259] - reverse L hall of Blackroot

ff: + 05: [260] - final warp room in Cape of Death

ff: + 06: [261] - room before Warlord Hammer

ff: + 07: [262] - room before Warlord Viper

ff: + 08: [263] - outside Blaise's house in Zagar Swamp

ff: + 09: [264] - outside Druas's house in Zagar Swamp

ff: + 0a: [265] - inside Druas's house

ff: + 0b: [266] - inside Blaise's house

ff: + 0c: [267] - Tone's Key
If you warp in on a pit you will immediately fall as soon as you close the menu. This happens just as the Gnome Prince is starting to talk so you will need to hit a button down in the pit to close the now-invisible dialogue box.

ff: + 0d: [268] - pit under the forest maze

ff: + 0e: [269] - air key ledge, transformed into a bird and it sounds like Arthur is under attack and the game freezes up if he reaches 0 health
This is another chance to screw with graphics loading and getting into things you shouldn't. Normally you'd never have access to the menu on this screen so entering and exiting submenus starts a chain of access errors. This is fastest if you have a full party but works for just Arthur. Enter and exit a submenu enough times and you'll see lines of graphic mess through the middle of the screen.  However at the top left you'll see Warlord Hammer.

If you then warp to another screen with enemies you can fight Warlord Hammer but he will be invulnerable to shield attacks. Care must be taken not to wander too far away from him, however, or he will effectively despawn in the same manner that normal enemies will. Arthur's shield attack graphic will then be overwritten by Hammer's main sprite. Exiting the screen by walking to a new location clears up all visible errors although it is unclear at this time if this can have lingering effects down the road.

There are more ramifications then I can explain in this short blurb: This video link will take you to a loading experiment and a playlist with more videos of this nature.

ff: + 0f: [270] - screen with ominous shadow

------------------------------------------------

ff: + 10: [271] - Plain of the Dead, forest floor
This warp crashes if performed at the very start of the game before selecting two initial allies.

ff: + 11: [272] - Plain of the Dead, overhead maze

ff: + 12: [273] - City of the Dead

ff: + 13: [274] - house in City of the Dead

ff: + 14: [275] - house w/warlord trooper, if you have allies you can escape as allies don't seem to be bothered by not being able to get enemies into range, also, the trooper will be cloned w/a dummy

ff: + 15: [276] - another house in the City

ff: + 16: [277] - other house w/warlord trooper

ff: + 17: [278] - mansion room

ff: + 18: [279] - mansion room w/fireplace

ff: + 19: [280] - throne room of mansion

ff: + 1a: [281] - room in the mansion w/3 beds

ff: + 1b: [282] - mansion room w/small fireplace

ff: + 1c: [283] - hallway of mansion

ff: + 1d: [284] - room in mansion

ff: + 1e: [285] - library of mansion

ff: + 1f: [286] - main hall of mansion

------------------------------------------------

ff: + 20: [287] - room in mansion

ff: + 21: [288] - room w/ton of candles, mansion

ff: + 22: [289] - dead chapel

ff: + 23: [290] - long hallway, was unable to move at all Can warp to the top of the hall but the tiles a little ways down are all set as impassable.

These stairs share the same screen as the door to the Stone Gardens. By repeatedly warping back and forth to the Plain I was able to get to the stairs at the bottom and was sent immediately to the cliffs south of the Cape of Death. This spot immediately sends you one screen south.

ff: + 24: [291] - crash

ff: + 25: [292] - crash

ff: + 26: [293] - crash

ff: + 27: [294] - crash

ff: + 28: [295] - crash

ff: + 29: [296] - crash
