GAC Studio Plus · Sidon Edition

Retro adventures, modern toolchain.

GAC Studio Plus takes the spirit of the original 8-bit Graphic Adventure Creator and rebuilds it for today: big maps, rich NPCs, branching dialogue and export paths to classic machines and modern engines.

Focus: Text & graphic adventures
Platforms: Web editor · Desktop tools
Status: Early access, actively evolving

Closed Beta: The web editor is currently being tested by a small invited group while parser stability and core workflows are refined.

What GAC Studio Plus aims to be

A bridge between the simplicity of classic 8-bit tools and the ambition of modern narrative design.

World
Big-picture map first
Start with regions and rooms on a large world canvas. See your adventure structure before you worry about wording every line of text.
Region clusters · 16-point compass · Visual flows
Narrative
Room text & puzzle logic
Write descriptions, add objects and wire conditions using a readable, structured approach. The underlying model is designed to export cleanly to multiple runtimes.
Descriptions · Objects · Local & global flags
Characters
NPCs and conversations
Bring your worlds alive with NPCs that move, remember and react. Dialogue trees, scripted triggers and alternative responses are all part of the long-term plan.
Dialogue trees · Presence by room · Script hooks
Output
Old machines & new engines
The same project data can eventually be compiled for BBC Micro / C64 style engines, modern interpreters, or even visual novel / point-and-click hybrids.
GAC-style export · API for future runtimes

Roadmap · where the project is heading

The current web editor is a prototype focused on the core data model. Desktop builds and deeper AI-assisted tools will follow.

Now
Web editor prototype
Browser-based editor with regions, rooms and exits. JSON export/import to keep your projects safe while the tool evolves.
  • • Regions & rooms in one view
  • • Exits wired via compass
  • • Auto-save to local storage
Available
Next
NPCs + playtest
Add NPC data, basic dialogue support and a simple in-browser runner so you can walk through your map like a player.
  • • NPC presence per room
  • • Simple conversation trees
  • • Text-mode playtester
In development
Later
Desktop suite
A richer Avalonia desktop version with plug-ins, batch exports, and deeper debugging tools, powered by the same JSON core as the web app.
  • • Dedicated map canvas
  • • Build pipelines per platform
  • • Diagnostics & test harness
Planned
Future
AI helpers & marketplace
Optional AI assistants for room text, puzzle ideas and NPC dialogue, plus a marketplace for sharing templates, modules and full adventures.
