Open Source C# Emulators

Locale Emulator is a tool similar to AppLocale and NTLEA, providing a simulation function that can make an application recognize your OS as in a language other than the real one. It is quite useful when you are trying to play country-specific games. Locale Emulator is compatible with the following systems, both 32 and 64-bit, Windows 7 with Service Pack 1, Windows 8.1, and Windows 10. Locale Emulator supports 32-bit executables running on both 32-bit or 64-bit systems. For example, if you are using 64-bit WinRAR, you will not see the context menu on a RAR file unless you swapped 64-bit WinRAR with the 32-bit version. Clone the repo using Git, install Microsoft Visual Studio 2015 / 2017, open LocaleEmulator.sln, perform build action, clone and build the core libraries, and copy LoaderDll.dll and LocaleEmulator.dll from Locale-Emulator-Core to Locale-Emulator build folder.

V.Dream is a V.Smile emulator developed by Néo Foderé de Frutos under the FODSOFT™ brand and written in C, C#, and XAML. The V.Dream core is based on V.Frown, an emulator originally developed by Ian (Schnert0) and other contributors. With V.Dream, you can play and relive the games from your childhood or discover them for the first time, develop your own software with instructions for the emulated hardware, among other features. It should be noted that neither FODSOFT™ nor V.Dream provide ROMs or any other means that facilitate piracy; the only thing FODSOFT™ offers is software that simulates the hardware of that era so the games can run on modern devices. V.Dream is an independent project of FODSOFT™ and is not affiliated with, endorsed by, or in any way connected to VTech® or any of its subsidiaries or affiliates.

Utility to edit CDT files (Amstrad Tape)

"Slow CPU" Emulator is useful for slowing down games, testing how applications deal with lag, and/or reducing the overall CPU usage of a specified process. Simply tell the emulator the update interval and speed percentage, and witness your application slowing down to the specified speed live! The code is written in C# for Windows and is extremely robust, flexible and stable, and has been tested very thoroughly. I apologise in advance for the code not being very readable, sometimes spaghetti code is more optimised code. ;) If you encounter any issues, do not hesitate to tell me. :) License: MS-PL Do whatever you want with the code. Credit would be nice, but definitely not required. I am not responsible for any undesired or unintended effects that may (most probably won't) come up as a result of using the application.

For instructions on how to use, see this file: https://sourceforge.net/projects/techsupportcmd/files/How%20To%20Use.pdf/download This fake command prompt can be used instead of the real windows command prompt in order to waste the tech support scammers time. It is based upon the windows 7 command prompt, but is not noticeably different from the command prompt in most other windows versions. Many commands commonly used by scammers, such as tree, netstat and powercfg are emulated in this, but they provide results that the scammer would not be expecting, for example, the tree command draws an ASCII tree, while the powercfg command comes back with no errors, no warnings and no informational - every time, without fail. Commands not included all come back with the usual error as displayed for invalid commands in the real command prompt, however other commands can be added.
