This project was originally designed to provide an open-source replacement for PPJoy. The product, at this point, consists of virtual joystick devices that is seen by the system as a standard joystick but its position-data is written to it by a feeder application. An existing feeder application that takes advantage of this product is SmartPropoPlus. If you are an application writer you can very easily write an application that controls a joystick (e.g. mouse-to-joystick, keyboard-to-joystick). If you are a beginner in device drivers you can take this code and enhance it to support more (or less) axes, buttons or POVs.

This file integrity checker uses Alternate Data Streams to store the hashes of your files. So, it only works on NTFS volumes. With that, you can rename, copy or move your files (to another NTFS volume) without losing the hashes, and without needing to do anything else. The Whirlpool algorithm is a strong 512-bit hash function. This tool uses several optimized implementations with SSE4.1 or SSE2 instructions when available. Each folder is recursively processed. You can use drag-and-drop, mix files and folders, pause and resume. 64-bit: https://sourceforge.net/projects/whirlpoolfilech/files/0.5/WFileCheck64.exe 32-bit: https://sourceforge.net/projects/whirlpoolfilech/files/0.5/WFileCheck32.exe At first use, please let the integrated benchark determine the fastest procedure for your hardware. "Fast" will only take a few seconds. Minimum requirement: Windows XP or later.
