System Requirements Document for pokevr

1. Introduction

The pokevr project aims to create a playable VR version of the classic Pokemon games: Red, Green, Blue, Yellow, Gold, Silver, and Crystal. The product is designed for players who wish to experience these games in a virtual reality environment with two distinct modes: a first-person mode and a diorama mode. The product will not include any copyrighted assets, and users must supply their own ROMs.

2. System Overview

pokevr provides a VR experience for classic Pokemon games, allowing players to explore the game world in two modes: first-person and diorama. The system ensures compliance with copyright laws by requiring users to supply their own ROMs. The product is designed for a single player, referred to as the "Player," who interacts with the game through a VR headset.

The pokevr system is delivered as a VR application that supports Pokemon Red, Green, Blue, Yellow, Gold, Silver, and Crystal. It includes no copyrighted assets, requiring users to supply their own ROMs. The application features two modes: a first-person mode for immersive exploration and a diorama mode for a toy-like, manipulable view of the game world. The application is designed to be playful and engaging, following the creative direction inspired by Bruno Simon's immersive gaming environments.
