Openspeedy

OpenSpeedy is an open-source tool designed to modify the execution speed of applications and video games. It functions by manipulating system-level time-related functions, allowing speed adjustments for both x86 and x64 processes. The software employs user-space (Ring3) hooking techniques to intercept time-related calls without affecting the system kernel. Its technical implementation focuses on modifying critical APIs such as GetTickCount, timeGetTime, QueryPerformanceCounter, and game engine-specific timing functions.

• Speed modification. Allows altering the execution speed of applications through customizable multiplier adjustments. Values can be configured according to the specific requirements of each application, with options ranging from reduced speeds to significant accelerations.
• Architecture compatibility. Support for both 32-bit (x86) and 64-bit (x64) processes. The tool automatically detects the target process's architecture and applies the appropriate hooking methods for each case.
• Time API interception. Implements hooks in system functions related to time measurement, including GetTickCount, timeGetTime, QueryPerformanceCounter, and others. This interception allows modifying the target application's perception of time.
• Command-line interface. Provides configurable parameters via command line for automation and integration with other systems. Settings can be specified directly when running the tool without requiring graphical interaction.
• Manual injection mode. Offers flexibility in the injection methodology, allowing both automatic and manual injection according to user preference. This approach supports various usage scenarios and compatibility with different environments.
• Low resource consumption. Designed with efficiency as a priority, maintaining minimal impact on system performance during operation. The additional overhead generated is marginal on most modern hardware.
• User-space hooking. Utilizes memory modification techniques at the Ring3 level, avoiding operations requiring kernel privileges. This approach reduces system stability risks and improves portability across Windows versions.
• Multiplier customization. Granular speed adjustment system using decimal values. The multipliers allow precise increments and decrements based on the specific needs of each application.
• Game engine compatibility. Includes specialized hooks for timing functions of common game engines, improving compatibility with titles developed using specific technology.
• Process monitoring. Ability to identify active processes and select targets for injection. The tool lists available processes with relevant information to facilitate selection.
• Exception management. Built-in mechanisms to handle errors and exceptional situations during the injection and modification process. The system reports operational statuses for diagnosis when necessary.
• Persistent configuration. Ability to save and load custom configurations between sessions. Settings can be preserved for frequently used applications.

OpenSpeedy was created by the developer known as game1024. The project began development in 2023 and is primarily programmed in C++, leveraging Windows APIs to implement its functionalities. The source code is publicly hosted on GitHub under an open-source license, allowing for inspection, modification, and distribution of the software. The codebase continues to evolve with contributions focused on improving compatibility and adding support for new timing APIs.
