TechTuber creates modern VHS-based FMV game system for Doom and Super Mario Bros.

Modernizing VHS Gaming

A TechTuber, known as Throaty Mumbo, developed a new gaming system that utilizes VHS tapes for Full Motion Video (FMV) gameplay. This project was initiated due to dissatisfaction with the limited interactivity of the 1987 ActionMax VHS-based console.

Technical Implementation

The new system integrates modern hardware components, specifically a DE1-SoC FPGA board and a Raspberry Pi RP2350 MCU. This setup allows for enhanced interactivity and graphical overlays not possible with older VHS gaming systems.

For the Doom adaptation, the FPGA manages overlay graphics and switches between eight simultaneous video streams from the VHS deck. Player interaction determines which stream is selected, and a counter tracks button presses for scoring.

Game Adaptations

The system features custom versions of classic games. The Doom version offers an on-rails experience, focusing on audio/visual fidelity rather than original gameplay mechanics. The Super Mario Bros. adaptation maintains the original game's appearance but replaces its backdrop with VHS-taped imagery, a technique previously seen in early CD-ROM games.

Inspiration and Precedent

The project draws inspiration from the limitations of the ActionMax, aiming to improve upon its basic interactive video concept. This endeavor follows Mumbo's previous work, such as running Sega games from vinyl records, demonstrating a continued interest in unconventional tech applications.
