MSXTT is a live NOS Teletekst viewer for MSX1 and MSX2(+) computers, bringing the classic Dutch NOS Teletekst experience to your MSX.

It lets you browse familiar Teletekst pages directly on real MSX hardware, with an interface designed to stay very close to the look and feel of the original service. MSX1 systems are fully supported as well, using SCREEN 2 with an adapted color palette.

The font is based on the original SAA5050 5×9 Teletext character set used in Mullard/Philips Teletext systems, including special characters but with a few adjustments to accommodate the smaller MSX pixel raster.

Note: MSXTT requires an MSX-UNAPI compliant network interface, such as the Pico+ cartridge from msxpico.com.

Current release is a beta version and has only been tested with Pico+. More info and manual are on GitHub.

Download the beta version .COM format from file-hunter.com (For Pico+ users: 1. Place .com on the Pico+ SD card 2. Select Nextor+WIFI from the menu.)

Happy to receive your feedback and thoughts!

FAC Soundtracker 2+ Web is a native browser recreation of the original FAC Soundtracker software for MSX computers (1990/1991). It reproduces the classic editor UI without relying on MSX emulation.

The 2+ Web edition keeps the original 1:1 interface, including period localization and key shortcuts (MSX GRAPH maps to Alt / Option), and adds web-oriented extras:

• Mouse-friendly grid and clickable softkeys
• Drag & drop `.MUS`, disk images, and archives (`.ZIP` / `.LZH` / `.PMA`)
• WAV import into ADPCM memory
• MIDI keyboard support (replaces the Philips NMS-1160 music keyboard)
• System audio input (replaces Music Module mic/line)
• All five FAC Music Disks and four Sample Disks bundled

Source, manuals, and documentation like file-formats are on GitHub.

TouchDesigner is a node-based visual programming platform widely used for real-time generative graphics, interactive installations, projection mapping, and live visual experiences. Get inspired by the many examples on YouTube.

This experiment explores how TouchDesigner could also function as a visual prototyping environment for MSX and retro-computing graphics algorithms.

Different input sources can be used — images, video, webcam streams, music/MIDI, or scripts that generate procedural motion such as fluid, lava, or ocean-like patterns. The resulting visuals can then be processed through custom encoders that reproduce the graphical constraints of MSX screens, allowing you to preview in real time how the content could appear on actual MSX hardware.

By combining TouchDesigner with openMSX, the workflow can extend beyond visual prototyping. Both environments can be controlled from an AI-assisted development environment, making it possible to generate, convert, port, and test visual content rapidly across the modern real-time pipeline and the emulated MSX system.

The result is a bridge between contemporary generative media tools and retro-computing constraints: a fast, visual way to experiment with algorithms before translating them into native MSX implementations.

snAIk is a simple Snake-inspired arcade game for MSX1, built end-to-end with AI.

The game itself is compact. Its main purpose is to demonstrate what an AI-oriented MSX development stack can produce.

Tools, IDE setup, and the overall approach are documented in the MSX-AI-Dev-INIT GitHub repo. You can use it as a starting point for your own MSX-related AI experiments.

Play snAIk directly in the browser via WebMSX, made possible by File-Hunter.

Hardware/software exploration of converting AY-3-8910 (PSG) register data to Eurorack control voltages. The goal is to drive modular synths from classic chip-tune pitch and modulation data while keeping original tuning and frequency-modulation behaviour intact.
A SoundCloud sketch demonstrates how the chiptune sound can be exactly recreated using Aleste game music material as source.

Space Invaders visualizer – prototype.
Eurorack - 6hp

Prototype features:

• The classic Space Invaders game, now invading your eurorack setup.
• Starring Squid, Octopus, Crab and Cuttlefish
• Four different animations that can be combined to match your creativity
• Walk, moves the invaders 1 pixel left or right and animates the walking motion.
• After 32 gate signals, the invaders change direction and move one row down or up.
• Fire, shoot! from a random position. the Invader flashes white when hit
• Crash, inverts the entire display (negative)
• Zoom, 2x zoom level
• Crash and zoom length depend on your gate signal length
• 1 knob to set the display brightness level
• 1 knob for color selection

AstroVibe visualizer – prototype.
Eurorack format - 6hp

Prototype features:

• Visualizes the incoming (line-level) audio signal
• Starfield visualization with animation and colors driven by the input signal
• More energy = more stars
• Kick and snare detection with visual feedback
• Classic EQ mode, 7->10 bands
• Knob controls for Brightness, Color selection and Attenuator
• Thru jack outputs the input signal (trs)

Midi live monitor – prototype.

A compact MIDI utility that listens to MIDI clock and transport and displays playback status on a 16x2 LCD.
While playing it helps you keep track of song/track position.

Features include:

• Live BPM readout while playing
• Start/stop/clock/midi data status leds
• Song position / bar:beat style transport display
• Beat count

Created using a arduino connected to a midi shield and 16x2 LCD matrix connected via a breadboard.
