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
Open Web Editor Read the vision

Note: The web editor runs entirely in your browser and saves projects locally. Desktop builds will follow once the data model and flow are locked in.

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
