ENDGAME is a dashboard exploit for the Original Xbox that allows you to copy habibi-signed XBE payloads from a memory card and execute them automatically. This exploit is compatible with all retail kernel and dashboard versions and, unlike other softmod methods, does not require a game or even a working DVD drive — only a memory card.

ENDGAME was developed by Markus Gaasedelen (gaasedelen) with credit to shutterbug2000 for the initial discovery of the exploit vector and first proof of concept and to xbox7887 for minor contributions. The Xbox Softmodding Tool by Rocky5 utilizes this exploit to run the softmod installer. A video of this process can be found on MrMario2011's channel.

Softmodding your Xbox

Materials Needed

• A Female USB to Xbox controller port adapter such as this one from Amazon OR an Xbox memory card with another modded Xbox or GameShark/Action Replay to load the softmod installer onto the card.
• A USB flash drive that is 4GB or smaller (USB Compatibility List) or an Android device using DriveDroid. You do not need either if you are using a memory card.

Running the Exploit

1. Download the Xbox Softmodding Tool.zip, open it, open the Softmod Package folder, and extract the contents of Endgame.zip. It should be a folder named helper, a folder named trigger, and a file called payload.xbe.
2. Copy the helper folder, trigger folder, and payload.xbe to the root of your flash drive or memory unit.
3. Plug the memory device into your controller and turn on the Xbox. Select "Memory", then click your memory device. It will freeze for a minute and then the LED ring on the front of your Xbox should cycle colors before booting into the softmod installer.
   • If it does not boot into the softmod installer within a minute after cycling the LED ring colors, turn off your Xbox and try again.
4. Press A to install the softmod. Read the prompts that come up and press A to acknowledge them. Your Xbox will reboot.
5. The tool will finish setting up. You will be left on the Xbox Softmodding Tool dashboard, which is just a skinned UnleashX dashboard. You can change the skin under System → Skins.

(Optional) Nulling your HDD Key

After you have softmodded the Xbox, you may optionally "null" or "uno" the HDD key. Only do this step BEFORE registering your console to any Xbox Live replacement service and only if you wish to swap hard drives between multiple Xbox consoles or know you will be unable to keep a backup of your Xbox EEPROM information. This will change the Xbox's unique thirty-two digit HDD key to 11111111111111111111111111111111 (thirty-two ones). This will allow you to always know what your HDD key is and it will make it easier to rescue the Xbox from HDD failure in the future. All you will need to build a new hard drive is another Xbox that also has an all 1 HDD key or FatXplorer. To null your Xbox's HDD key, launch NKPatcher Settings from the Applications menu, go to EEPROM > Advanced Features > Hard Drive > Change EEPROM HDD Key.

• If you softmodded with an installer other than Rocky5's Xbox Softmodding Tool, make sure you upgrade to the Xbox Softmodding Tool before you null your HDD key, otherwise you may end up getting error code 06, due to older softmods using a virtual EEPROM.
• Previous versions of the Softmodding Tool set the HDD key to thirty-two zeros. Starting with v1.1.8, it has now been changed to use all number ones, this to be ready for Insignia's release, because the thirty-two zeros wouldn't work with that system. Both thirty-two ones or thirty-two zeros will null, however, if one wants to be ready for Insignia use all 1’s or 31 zeros and a 1; just as long as it’s not all zeros. Either way, one should be aware that both a null of all 1s or null of all 0s may exist in the wild.
• "Nulling" or "Unoing" your HDD key is not a substitute for keeping good backups of your Xbox EEPROM information. Your eeprom.bin and other relevant information are located in the E:\Backups folder on your Xbox. Ensure the folder includes an eeprom.bin file, then back up the folder to your PC and preferably to some form of cloud storage as well, as it is critical for building a new hard drive for your Xbox.
• "Nulling", "Unoing" or changing your your HDD key in any way will break the signature for many saved games as well as all DLC and Title Updates installed on your console. Some of the games with signed saves can be re-signed using tools found on this page about EEPROM-locked saves. DLC and Title Updates can be re-signed with FeudalNate's Content Recovery Tool.
