"Hey you, you're finally awake..." Welcome to the Terminal.

I'm an IT Support Specialist by day and a builder of retro-inspired software, homelab infrastructure, custom hardware, and strange little computer systems by night.

I hold the CompTIA A+, Network+, Security+, and CySA+ certifications, and most of my personal work lives somewhere between practical IT, defensive security, retro computing, and:

"What if this modern machine felt like it came from another timeline?"

Latest completed milestone: v0.31 — Maintenance Terminal
Next development milestone: v0.32 — Guided First-Launch Setup

Veyllisto Interface Engine is an open-source, Python-based retro-computing interface and game-launching engine built around one simple idea:

Modern hardware. Retro experience.

🌐 Website: veyllisto.com
🖥️ Live Demo: veyllisto.com/demo/

Veyllisto is built around a modular Engine + Shell architecture.

The Engine owns shared systems such as the game library, Steam and emulator integration, metadata, favorites, recent history, physical media, configuration, and hardware integrations.

Shells provide completely different ways to interact with those same systems.

One Engine. Shared state. Multiple experiences.

Veyllisto v1.0 is planned to ship with four first-party interface shells:

• 📟 Terminal — keyboard-first immersive retro terminal
• 🖥️ Classic Desktop — late-1980s / early-1990s graphical desktop
• 🎮 Living Room — controller-first television and couch-gaming interface
• 🕹️ Arcade — cabinet-style game-first experience

Each shell uses the same underlying Veyllisto Engine and shared library state.

Recent completed systems include:

• Unified Game Library
• Steam integration
• Emulator and ROM launching
• Favorites and Recently Played
• Physical-media detection
• Metadata-only physical launch keys
• Self-contained physical game media
• Multi-game physical collections
• Built-in Physical Media Creator
• Safe removable-media writing and verification
• OLED / auxiliary-display support
• Configurable machine identity
• Theme-owned custom audio
• Callisto Green, Amber, and White reference themes
• Authenticated Maintenance Terminal
• System diagnostics
• Controlled Desktop Mode
• Advanced Terminal access
• Process-level Veyllisto restart
• Protected host reboot and shutdown actions
• Context-aware Settings and Maintenance navigation

Big vision. Small versions. Stable checkpoints. No chaos.

When I'm not working on Veyllisto, I spend time experimenting with physical and virtual infrastructure.

Building domain environments for:

• Group Policy
• DNS
• Authentication
• Networking
• Administration
• Troubleshooting

Running lab environments for:

• Traffic analysis
• Incident-response practice
• System monitoring
• Security testing
• SOC-style simulations

Giving retired enterprise hardware a second life through:

• Servers
• Retro-computing projects
• Lab systems
• Custom PCs
• Experimental builds

Building and maintaining services and systems inside my home lab.

Veyllisto is open source under the MIT License, and the long-term goal is to make the platform something other builders can experiment with too.

Interested in:

• Retro computing
• Custom user interfaces
• Emulation
• Physical media
• Fictional computer systems
• Homelabs
• Hardware reclamation
• Defensive security

Take a look around.

Modern hardware. Retro experience.
