    V.Dream

    V.Dream

    V.Smile emulator written in C, C# and XAML

    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. V.DREAM DOES NOT ACCEPT DONATIONS. © 2025 FODSOFT™. Néo Foderé de Frutos. All rights reserved.
