A FAMILIAR WORKFLOW

From your first scene to a PS1 build.​

Arrange your world visually, add behaviour with components and Lua, then export a game for the original PlayStation.

Create visually

Scenes, components, geometry, and UI in one editor.

Write gameplay in Lua

A lightweight scripting workflow for your own game logic.

Export native PS1 games

Build disc images for a separately configured emulator or compatible homebrew setup.

01 / CREATE YOUR WORLD

Build your levels in the editor.​

Start with a blockout and shape it into a playable space. Keep geometry, materials, and scene objects together in a dockable workspace.

  • Create and edit geometry with Level Builder.
  • Adjust textures with UV Editor and import your assets.
  • Organize GameObjects and assign components in the Inspector.

02 / BRING IT TO LIFE

Your game logic. Your interface.​

Write Lua behaviours, connect them to your scene, and build the interface your game needs. Try changes in Play Mode as you work.

  • Script input, interactions, and scene changes with Lua.
  • Arrange panels, text, images, and buttons in UI Canvas.
  • Add audio and save data to complete the experience.

03 / BUILD FOR PLAYSTATION

Work with the hardware in mind.​

Make decisions with the original console’s limits in view. Inspect resource usage while you build, then test the exported game.

  • Review content budgets with PS1 Budget.
  • Inspect textures, palettes, and framebuffers in VRAM Inspector.
  • Export BIN/CUE or ISO images with NTSC and PAL options.

Emulators and BIOS files are not included. Test exported builds on your intended setup; resource checks do not guarantee hardware compatibility.

LEARN BY MAKING A GAME

Start with a project you can follow.​

Follow Two-Room Relay from an empty project to an exported game, or explore the included examples to see how the pieces fit together. Documentation is available in English and Spanish.
