ARUAN'S ENTERTAINMENT SOFTWARE.

A cross-platform emulation frontend and multimedia engine, forged on Avalonia. Born as @ES seventeen years ago — a personal challenge to push a UI framework to its absolute limit — now rebuilt for a new decade of hardware.

Acquire the build.

Live from GitHub Releases. Stable and pre-release channels, every desktop platform — AOT and runtime variants. Click a row to download.

AOT (Ahead-of-Time) builds are self-contained — no .NET runtime installation required. Runtime builds require .NET 9+ to be installed on the host.

Supported systems.

Per-platform profiles with art and metadata. Frontend integration for over two decades of hardware.

05

Shader engine.

Plasma6-style wallpaper shaders run as live backdrops. Drop any Shadertoy-compatible .frag into Shaders/Shadertoys and AES renders it. Selected shaders bind to the player's audio spectrum and react to your music — a demonstration feature, fully removable.

A long arc.

Seventeen years from @ES to Lacrima.

  1. 2008

    @ES is born

    Created as a challenge to master WPF and push it to its limits, within a small emulation community.

  2. 2024+

    The revival

    The project is revived as AES — Lacrima, rebuilt on Avalonia for cross-platform reach and modern GPU shaders.

  3. now

    Active research

    Content is pushed incrementally while the codebase is cleaned and organized — a living study in framework mastery.

Push a UI framework
to its limit.
