Survival: Day (Hard) - game#_6 (# is the user number so look for game1_6 if user 1) Survival: Night (Hard) - game#_7 Survival: Pool (Hard) - game#_8 (not needed because Survival: Endless is in a pool setting) Survival: Fog (Hard) - game#_9 Survival: Roof (Hard) - game#_10 Survival: Endless - game#_13
 * 1) Pick plants in a Survival: Hard game and leave after starting it.
 * 2) Go to the userdata folder (C:\ProgramData\PopCap Games\PlantsVsZombies\userdata) and rename the saved file of a Survival: Hard game to Survival: Endless (game#_13).
 * 1) Go to Survival: Endless and play it.

Survival: Night Roof (Endless)
This cheat allows you to play Survival: Endless on the Roof during nighttime. There are two known methods of doing so.

Without external programs
This method can be achieved with just your computer's file directory.


 * 1) Play Dr. Zomboss's Revenge until you have 10 seed slots filled. This reduces the chance of your game crashing, though it is possible to have fewer seed slots filled.
 * 2) Exit the level. The data should be saved.
 * 3) Find where your game data is located. By default, it should be found in this order:
 * 4) Your hard drive.
 * 5) ProgramData
 * 6) Publisher File (for instances, I downloaded the game via a Safari Games disc so my folder would be named "Safari Games". Your file may be named differently.)
 * 7) PlantsVsZombies
 * 8) userdata
 * 9) Rename data game#_35 to game#_30. (# is your user number. If you did this under the first account created, it would be 1.)
 * 10) Access Whack a Zombie and attack Dr. Zomboss right away. Hit zombies until you have at least 350 sun.
 * 11) Now leave the level and go back to your userdata. Rename data game#_30 to game#_10. (or any number from 6 to 10)
 * 12) Head to the Survival: Roof (Hard) (or the Survival Hard mode that you picked) and play it until flag 8.
 * 13) Leave the level and rename your save data from game#_10 (or game#_6 to game#10) to game#_13.
 * 14) Enter Survival: Endless and continue your game from there.

With Cheat Engine
This method will make it a lot faster to play Survival: Endless on the Roof while it is nighttime. However, you need Cheat Engine.

Preparations

 * 1) Open up Cheat Engine and the game.
 * 2) Make sure in the select process window (popup when you click the flashing computer button) you select either popcapgame1.exe or PlantsVsZombies.exe depending on the game version.
 * 3) Go to Zombotany (or any level. You just need its ID number.) and type 16 in the search bar. Click "New Scan" or "First scan" (depending on Cheat Engine version)
 * 4) Go to another level. In this case, we choose Last Stand.
 * 5) Type 31 (or the ID of the level you chose) in the search bar and click "Next Scan".
 * 6) If there is one address, select it. If not, go back to the first level you chose and scan its ID number. If there is still more than one address, go back and forth between the two levels you chose until you get only one address.

The actual cheating

 * 1) Head to Dr. Zomboss's Revenge but before the screen fully scrolls to the right, quickly change the value from 35 to 16 (or any Choose your Seeds level).
 * 2) Select the plants you want to bring for Survival: Endless.
 * 3) Start the level but before the screen scrolls back to the left, change the value to 35 (or any conveyor-belt levels like Column Like You See 'Em).
 * 4) Wait for all your seed slots to be filled first.
 * 5) Change the value from 35 (or the conveyor belt level's ID) to 30. Defeat all the zombies on the screen and Dr. Zomboss until you get some sun.
 * 6) Change the value to 13 and continue your game from there.

Last Stand Endless on PC
Last Stand Endless can be played on the PC version by modifying a saved file of Survival: Endless to Last Stand after flag 11 but only the zombies in the Last Stand mini-game will appear and the same choice of plants will be used in every round.


 * 1) Play Survival: Endless until flag 11.
 * 2) Go to userdata folder and rename game#_13 to game#_31.
 * 3) Go to Last Stand and the game will be endless.

Alternatively, you can use Cheat Engine. Do what you would do above but change the value 13 to 31. You will be in Last Stand automatically.

You can also use this hack to play Last Stand in different areas (Day, Night, Fog, Roof). Just rename the save files of the respective survival levels to game#_31 (See I, Zombie hack for the names of the save files).

Zombie Nimble Zombie Quick in normal speed
Play Zombie Nimble Zombie Quick. Open Cheat Engine, enable speed hack, and adjust it to 0.5. Play the game at normal speed.

Win Slot Machine instantly

 * Note: If you are trying for the Lucky Spin achievement, it is not advised to use this hack.

Requirement:
 * Plants vs Zombies
 * Cheat Engine

Steps:
 * 1) Open both requirements.
 * 2) Open Slot Machine.
 * 3) Scan the current amount of sun.
 * 4) Spend or gain some sun.
 * 5) Double-click the address (if there's 2 or more address,Repeat step 3 and 4)
 * 6) Replace value with the goal (2000 sun).
 * 7) DONE

Spawn any zombies
This allows you to spawn zombies anytime and anywhere you want.

To do this, you'll need:
 * Original version of Plants vs. Zombies (not the GOTY one)
 * PvZ Tools

Steps: Notes:
 * 1) Open Plants vs. Zombies and PvZ Tools.
 * 2) Go to any level.
 * 3) Switch to PvZ Tools. Uncheck "Pool Level," even when you're on it, and select lanes 1, 2, 3, 4, and 5 (and 6 if you're playing on a pool/fog level).
 * 4) For the zombie selection, pick the second radio button (which says "Zombie") and change the zombie to anything you want, then click "Spawn Zombie".
 * 5) You should see that there's a zombie spawned.
 * 6) Repeat steps 4 and 5 to spawn more zombies. It makes for some bizarre screenshots.
 * Using the "Edit probabilities" option allows you to randomize the zombies to be spawned, with adjustable sliders for each zombies' spawn rates.
 * The timed loop mode allows for an automatic spawn of zombies at set intervals (defined in milliseconds) when active.
 * This allows for an AFK gameplay of I, Zombie Endless; just set the zombies to spawn, activate the timed loop mode and you're all set.
 * In Zen Garden, the zombies will eat or crush your plants, but they'll be restored if you leave and reenter the it.
 * In Zen Garden or Tree of Wisdom, if one of the zombies reaches the leftmost side of the screen, the game still displays the standard losing message "The zombies ate your brains!", and if you click the "Try again" button on Game Over dialog box, you'll start at the Zen Garden with all your plants restored or the Tree of Wisdom.
 * This can be used to make some minigames a lot harder

See the Almanac entries of "hidden" plants and zombies
This allows you to see the Almanac entries of Explode-o-nut, Giant Wall-nut, Sprout, all ZomBotany zombies, and Giga-gargantuar.

You'll need: Steps: Notes:
 * Plants vs. Zombies (any versions)
 * Cheat Engine
 * 1) Open Plants vs. Zombies and Cheat Engine, then select popcapgame1.exe (if present), or PlantsVsZombies.exe (if popcapgame1.exe isn't present).
 * 2) Go to Suburban Almanac, and select "View plants" (if you want to see hidden plants Almanac entries) or "View zombies" (if you want to see hidden zombies Almanac entries).
 * 3) Select Repeater (for plant), or Buckethead Zombie (for zombie).
 * 4) Go to Cheat Engine, then scan for 7 (for Repeater) or 4 (for Buckethead Zombie).
 * 5) Go back to Plants vs. Zombies and select Chomper (for plant) or Pole Vaulting Zombie (for zombie).
 * 6) Go to Cheat Engine, and this time, scan for 6 (for Chomper) or 3 (for Pole Vaulting Zombie).
 * 7) If you found one address, select it. If you found two, select the second address. If you found more than two, then repeat steps 3-6 until there are only one or two results.
 * 8) Right-click on the added address, then select "Find out what writes to this address."
 * 9) Go back to Plants vs. Zombies, then select any plant or zombie. Cheat Engine should now show an opcode. Click it, then click "Replace," after that, click OK.
 * 10) Go back to Cheat Engine main window, then change the value of the address you added to 49 (Explode-o-nut), 50 (Giant Wall-nut), or 51 (Sprout), if you choose to see hidden plants entries, or change it to 26 (Peashooter Zombie), 27 (Wall-nut Zombie), 28 (Jalapeno Zombie), 29 (Gatling Pea Zombie), 30 (Squash Zombie), 31 (Tall-nut Zombie), or 32 (Giga-gargantuar), if you choose to see hidden zombies entries.
 * 11) Finally, click on any plant or zombie, and you should see the Almanac entry of the hidden plant/zombie now.
 * 12) Repeat step 10 and 11 if you want to see another plant/zombie's Almanac entry, or repeat steps 2-11 if you want to switch from plant to zombie, or vice versa.
 * Explode-o-nut, Giant Wall-nut, Sprout, and Giga-gargantuar don't have any Almanac entry descriptions, but it might be possible to add them by editing the LawnStrings.txt.
 * All ZomBotany zombies use the same entry as the normal zombie, and therefore, it might be the reason why all ZomBotany zombies' names don't show up when you hover over them in ZomBotany or ZomBotany 2.
 * Attempting to go past those plant/zombie IDs will probably crash the game, but some IDs might not cause the game to crash.

Endless Minigames
This allows for any minigame to be endless, albeit with frequent crashing.

Needed: Steps:
 * Plants vs. Zombies (any versions)
 * Cheat Engine
 * 1) Find the minigame ID using the cheat engine and going between any two minigames and searching for their ID's (say, Zen Garden, 43 and Wall-nut Bowling, 17).
 * 2) Find the ideal area type and starting conditions (pool, roof, night, etc.) in any minigame or Adventure mode level.
 * 3) Before the screen pans to the right, replace the minigame ID number with 13.
 * 4) Choose your seeds and begin.
 * 5) Preferably before the screen pans to the left, replace the minigame ID with whatever minigame ID you want to make endless. A full list of ID's can be found at Hybrid mini-games.
 * 6) Preferably before the minigame's end, replace the minigame ID number with 13.
 * 7) Repeat steps 4-6 as needed or allowed (remember that you can crash at any time for any reason).

Instant-use plants explode instantly
This will make instant-use plants (e.g. Cherry Bomb or Ice-shroom) explode immediately after planted or woken up with Coffee Bean.


 * 1) In Cheat Engine, click on "Memory View."
 * 2) Press Ctrl+G and type either 00463408 if you're using the old version of the game, or 00466E22 if you're using the GOTY version, then hit Enter.
 * 3) Double-click on the highlighted address and replace "jne" with "je" without changing anything else, then hit Enter.
 * 4) Try using an instant-use plant. It should explode immediately after being planted or woken up with Coffee Bean (in the case of sleeping Ice-shroom or Doom-shroom).
