## What it is
Red Viper is a Nintendo Virtual Boy emulator for the Nintendo 3DS, continuing the work on r3Ddragon. It uses a dynamic recompiler and hardware-accelerated rendering to run officially licensed Virtual Boy games at full speed on 3DS hardware.

## Use cases
- play Virtual Boy games on a 3DS
- emulate the Virtual Boy with 3D support
- run Virtual Boy ROMs at full speed on original 3DS hardware
- use savestates and game saves for Virtual Boy games
- play Virtual Boy games with custom button mappings
- enable local wireless multiplayer for Virtual Boy games
- adjust color palettes and 3D depth for Virtual Boy games

## When to choose
- you have a modded 3DS and want to play Virtual Boy games
- you need full-speed Virtual Boy emulation even on original 3DS hardware
- you want 3D support and customizable controls for Virtual Boy games

## When to avoid
- you use a flashcart instead of Luma3DS custom firmware, since the dynamic recompiler requires it
- you want to emulate Virtual Boy on platforms other than the 3DS
- you need an emulator with an official license or commercial support
