SIGNAL RIDER

A Saturn action game about skating through a compromised digital world, collecting data, and reaching the next signal.

August 2026, earlier prototype line

Finding a shape

Early Project Y2K packages and successive SIGNAL RIDER prototypes tested the core idea before the current playable baseline. The V95 title preview shows one earlier visual direction.

Why it mattered: These versions remain part of the history; their names and artwork do not define the present build.

Historical prototype and title preview; precise capture hardware is not established.

A fuller title and identity

An approved V120 title preview introduced the skating character and the digital track as a single composition.

Why it mattered: The title began to communicate the character and setting together, beyond a logo alone.

A playable hardware baseline

Build SR-B0030 simplified some rendering, refined skating strokes and narrowed the heat hazards. David reported that the SAROO package worked and accepted it as the playable baseline.

Why it mattered: A documented working reference made later gameplay and presentation experiments easier to judge.

Putting the scenes together

The B0040 review sheet shows the title, character dialogue, HUD, shop and transition shutters in one place.

Why it mattered: It documents how game scenes began to form a consistent presentation around the skating playfield.

Rin and the interface

Later B0075 comparison material shows a coral skating suit, a four-wheel skate illustration, inset dialogue text and a restrained shutter glow.

Why it mattered: The character and information around the playfield became easier to recognize at a glance.

A later Terminus route

B0086 QA captures show Rin on the approach to a circular Terminus opening and in the outer route with operator dialogue.

Why it mattered: The screenshots record where level layout and scene presentation were headed after the earlier playable checkpoint.

SR-B0086 · preserved QA stills and SAROO package; exact capture target and hardware acceptance are not established by these images.

The Goddess Tourney

A character-led fantasy role-playing game whose older RPG Maker incarnation is being rebuilt in RPG Maker MV.

More than ten years ago

The original RPG Maker project

I began developing The Goddess Tourney more than ten years ago. After feeling nostalgic and looking for my old projects, I found a still-live online link containing the project and decided to pick it up again.

Why it mattered: The current MV game revives a personal project with a much longer history rather than beginning the premise from scratch.

Historical RPG Maker incarnation; the precise start date and authenticated media for this phase have not yet been established.

September 2026

A return in RPG Maker MV

The modernization moved Chapter 1 / Round 1 into MV, with new presentation and expanded systems. Early MV captures show the tile-based rooms and a soundtrack credits screen.

Why it mattered: The new engine provides room to revisit the story, controls and presentation while retaining the project lineage.

Chapter 1 through Round 1

The preserved B0026 gameplay evidence includes the opening room, a Forest Drake battle and a Chapter 1 ending screen marked Round 1 complete.

Why it mattered: The material shows a testable story arc, not only menus or isolated art.

Character art and dialogue checks

The current preserved production work includes dialogue staging, character-art integration and image regression checks. The latest one-file change adds a Calder alpha check without changing gameplay or the package inputs.

Why it mattered: Source checks can protect the art pipeline while a new playable package awaits validation.

GT-MV-B0037 source pointer · MV-Win package and runtime review still pending; B0026 remains the documented gameplay recovery base.

Sonic Saturn

A noncommercial fan experiment in making fast Sonic-inspired 3D play feel at home on the Sega Saturn.

Early September 2026

Beginning with SRB2 and Greenflower Zone

The first Saturn experiments concentrated on an SRB2 Greenflower Zone prototype: moving through the world, then adding basic game interactions and drawing distance.

Why it mattered: The experiments tested how much recognizable 3D Sonic play the Saturn could carry.

SRB2 GFZ1 R9D archive · recorded gameplay footage. The archive does not establish a real-hardware capture for this clip.

Mid-September 2026

A wider Sonic Saturn direction

The experiment broadened beyond a strict SRB2 port toward an original Saturn-sized route with bends, branching paths, jumps, rings and readable scenery.

Why it mattered: The measure became the feel and clarity of a fast game on Saturn, rather than a frame-for-frame PC reproduction.

Road and scenery in motion

B0085 produced a focused Beetle Saturn capture of a bright roadway, floating islands and the opening view. Later B0089 is the latest proven retrievable package in the preserved checkpoint; a B0090 source/package candidate was still awaiting read-back and runtime review there.

Why it mattered: The newer scene gives the prototype an authored sense of place while keeping the hardware acceptance question open.
