Guest Inventory Positions Hack

Author: Jay

Keywords: hack

Release date: May 12, 2025

Most current ztd date: May 12, 2025

Zip size: 675 bytes

Compatibility: All game versions

Description: In ZT, a building's information window includes icons of what the building sells. ZT allows those icons to be 34 pixels wide without them overlapping or touching. A guest's information window includes icons of what the guest bought. But ZT allows less space for those icons. So if the icons are 34 pixels wide, they can overlap. That does not hurt anything, but sometimes does not look good for some icons. This hack allows icons that are 34 pixels wide to be in the guest's information windows without overlapping.

If your main ZT folder already has a hacks or hacks-unused folder, put GuestInventoryPositionsHack.ztd in that folder. Otherwise if your main ZT folder already has a dlupdate folder, put GuestInventoryPositionsHack.ztd in that dlupdate folder. Otherwise put GuestInventoryPositionsHack.ztd in the Updates folder.

This is a hack of ZT's infogst2.lyt file. So it cannot be used at the same time as any other infogst2.lyt hack, such as particleUI_bigger_panels.ztd, particleUI_DreamEmerald_v1.ztd, particleUI_DreamEmerald_v1-PlusMoveablePurchaseMenu.ztd, or particleUI_LostAmethyst_v1.ztd.

No Box Rattling Hack

Author: Fern

Keywords: Hack

Date Released: 5 August 2025

File Size: 1 KB

Compatibility: All Game Versions

Description: This was a requested hack. When animals are in boxes in a zoo, Zoo Tycoon periodically causes the boxes to shake and usually also has the animals make sounds while the shaking occurs. This hack causes Zoo Tycoon to no longer do that shaking and animal sounds from the boxes. This hack is an animals.ai hack. So it cannot be used at the same time as any other animals.ai hack.

No Staff Hack

Author: Jay

Keywords: hack

Release date: August 27, 2022

Most current ztd date: June 13, 2018

Zip size: 434 bytes

Compatibility: All game versions

Description: This removes all staff (zookeepers, maintenance workers, tour guides, scientists, DRT bases, and marine specialists) from a zoo and no more staff can be hired until NoStaffHack.ztd is removed from ZT's folders. When new staff are hired, their staff numbers will continue from where the numbering left off. Normally NoStaffHack.ztd is used temporarily, such as to save a zoo without any staff or to see if it is staff causing ZT to crash. When NoStaffHack.ztd is used for a version of ZT that includes the DRT Base, the icon for the DRT Base will continue to be in the Hire Staff menu, but a new DRT base cannot be purchased until NoStaffHack.ztd is removed from ZT's folders. If there is a DRT Base in the zoo, the building will continue to be in the zoo, but it will not have a helicopter. If the zoo is saved, then NoStaffHack.ztd is removed from ZT's folders and the zoo is loaded again, any DRT Base in the zoo will still have no helicopter. So the DRT Base building will have to be sold ("fired") and a new DRT Base will have to be put in its place to have a helicopter again.

If your ZT has a dlupdate folder, place NoStaffHack.ztd in ZT's dlupdate folder. Otherwise put NoStaffHack.ztd in ZT's Updates folder. Then remove NoStaffHack.ztd from ZT's folders when it is no longer needed.

This is a hack of ZT's staff.cfg, staff1.cfg, and staff2.cfg files.

Have All Special Things Available

Author: Jay

Keywords: faster special animal and object availability

Release date: August 10, 2022

Most current ztd date: August 10, 2022

Zip size: 608 bytes

Compatibility: All game versions

Description: Other than MM's Kids Map, all ZT freeform maps have animals and objects become available at the start of certain game months. But 16 special animals and objects need certain tasks to be done to make them available. In CC and in MM with DD, these 16 special animals and objects are Christmas/Holiday Tree, Deinosuchus, Dolphin Statue, Fancy Grandstand, Iceberg, Jack-O'-Lantern, Mermaid, Orca Statue, Photo Booth, Sea Lion Statue, Seal Statue, Snowman, Triceratops, Trio Statue, Unicorn, and Yellow Brick Path. This ".ztd" makes those special animals and objects available immediately.

The preferred way to make all special animals and objects available is to use the "Unlock everything" button that is made available by developerMenuHack.ztd. That is the button that was used by the developers of ZT to make all animals and objects available, including the special animals and objects. That "Unlock everything" button also has the advantage over HaveAllSpecialThingsAvailableByJay.ztd in that it can be clicked at the spur of the moment while in ZT instead of when a zoo is loaded. Although developerMenuHack.ztd is the preferred way to make all special animals and objects available, it is okay if people use HaveAllSpecialThingsAvailableByJay.ztd instead to make all special animals and objects available. If HaveAllThingsAvailableByJay.ztd is used, then HaveAllSpecialThingsAvailableByJay.ztd does not have to be used.

If your ZT has a dlupdate folder, place HaveAllSpecialThingsAvailableByJay.ztd in ZT's dlupdate folder. Otherwise put HaveAllSpecialThingsAvailableByJay.ztd in ZT's Updates folder. Since saved games do not remember what things have been made available, HaveAllSpecialThingsAvailableByJay.ztd has to remain in ZT's folders if you want the special animals and objects to continue to be available. So although HaveAllSpecialThingsAvailableByJay.ztd is not a hack, if you have your ZT set up to work with a hacks folder, you can put HaveAllThingsAvailableByJay.ztd in that hacks folder instead of the dlupdate or Updates folder.

Have All Animals Available

Description: Other than MM's Kids Map, all ZT freeform maps have animals and objects become available at the start of certain game months. Some special animals and objects need certain tasks to be done to make them available. This ".ztd" makes all animals available immediately, including the special animals. Normally, there are some animals that need their research to be completed before they become available. This ".ztd" makes those available immediately as well. However, because of the way ZT works, if the game is saved and reloaded, those animals are usually no longer available until their research is done, even while the ".ztd" continues to be used. So if those are needed to be available again, research can be completed or the "Unlock everything" button in developerMenuHack.ztd can be used or HaveAllResearchCompletedByJay.ztd can be used.

The preferred way to make all animals available is to use the "Unlock everything" button that is made available by developerMenuHack.ztd. That is the button that was used by the developers of ZT to make all animals available, as well as all objects.

Have All Things Available

Release date: August 10, 2022

Compatibility: All game versions

Description: Other than MM's Kids Map, all ZT freeform maps have animals and objects become available at the start of certain game months. Some special animals and objects need certain tasks to be done to make them available. This ".ztd" makes all animals and objects available immediately, including the special animals and objects.

However, because of the way ZT works, if the game is saved and reloaded, those animals and objects are usually no longer available until their research is done, even while the ".ztd" continues to be used. So if those are needed to be available again, research can be completed or the "Unlock everything" button in developerMenuHack.ztd can be used or HaveAllResearchCompletedByJay.ztd can be used.

Other ways to make animals and objects available is to use developerMenuHack.ztd, MMFreeformUnlock.ztd, or ZooAdminMapEditor.ztd. The preferred way to make all things available is to use the "Unlock everything" button that is made available by developerMenuHack.ztd. That is the button that was used by the developers of ZT to make all things available. That "Unlock everything" button also has the advantage over HaveAllThingsAvailableByJay.ztd, MMFreeformUnlock.ztd, and ZooAdminMapEditor.ztd in that it can be clicked at the spur of the moment while in ZT instead of when a zoo is loaded. And developerMenuHack.ztd has the advantage over ZooAdminMapEditor.ztd in that it makes 7 of DD's rubble pieces available instead of only 1. Neither HaveAllThingsAvailableByJay.ztd nor MMFreeformUnlock.ztd make DD's rubble pieces available because ZT has them configured to be in the Developer menu instead of any other purchase menu. developerMenuHack.ztd also makes other developer objects available that HaveAllThingsAvailableByJay.ztd and MMFreeformUnlock.ztd do not. Although developerMenuHack.ztd is the preferred way to make all things available, it is okay if people use HaveAllThingsAvailableByJay.ztd or MMFreeformUnlock.ztd instead to make all things available. Neither HaveAllThingsAvailableByJay.ztd nor MMFreeformUnlock.ztd are hacks. But between the two, HaveAllThingsAvailableByJay.ztd is preferred over MMFreeformUnlock.ztd. HaveAllThingsAvailableByJay.ztd is more efficient. Also, HaveAllThingsAvailableByJay.ztd can make some user made things available that would not be available without using something else.

If your ZT has a dlupdate folder, place HaveAllThingsAvailableByJay.ztd in ZT's dlupdate folder. Otherwise put HaveAllThingsAvailableByJay.ztd in ZT's Updates folder. Since saved games do not remember what things have been made available, HaveAllThingsAvailableByJay.ztd has to remain in ZT's folders if you want the things to continue to be available. So although HaveAllThingsAvailableByJay.ztd is not a hack, if you have your ZT set up to work with a hacks folder, you can put HaveAllThingsAvailableByJay.ztd in that hacks folder instead of the dlupdate or Updates folder.
