Independent developer · game toolmaker · digital preservation

Raynor Eissens builds playable systems.

A Dutch independent developer working across browser games, retro-game tooling, fan localizations, AI-assisted archives and experimental interfaces.

The recurring pattern is practical rather than theoretical: combine things that normally live in separate tools, make them work together, and publish the result as something people can actually use.

About

Raynor Eissens is best described as a builder. His recent public work spans live game-state inspection, browser-native games, preservation projects, fan localization engineering, conversational archives and spatial interfaces for complex data.

Games + live data

Projects connect running games to information that is normally hidden, external or difficult to inspect.

Emerald Live · PSO research

Preservation + localization

Older games and print culture are reconstructed, translated, indexed and made directly usable again.

JRPG.WORLD · PU30JAAR

Browser-first worlds

Games and interactive systems are often designed to run immediately on the web, including mobile devices.

Kloojo · GPTGTA · Driftline GP

AI as a build layer

AI is used primarily as part of the production, synthesis and interface stack rather than as the sole product.

Selected work

These projects are representative of the public 2026 body of work. Claims below are intentionally narrow: they describe what the projects do without relying on broad “world first” language.

JRPG.WORLD — Emerald Live

Pokémon Emerald running in the browser with local inspection of the active game state. Wild and party Pokémon can be recognized during play and hidden Generation III values such as IVs, EVs, Nature, Ability, Gender and Hidden Power can be displayed without requiring a separate save export.

jrpg.world
PokéField

A persistent visual Pokémon population where commands can make matching Pokémon respond in place and FOCUS can reorganize the active field. The interface treats filtering as spatial behavior rather than a conventional result list.

pokefield.com
Kloojo

A browser-native 3D skate, graffiti and social-world project with synchronized multiplayer actions and a strong mobile-first development lineage.

kloojo.com
PU30JAAR

A multi-decade Power Unlimited archive transformed into a structured, page-retrievable and conversational corpus, including canonical review extraction and semantic retrieval across tens of thousands of pages.

pu30jaar.wolken.page
JRPG fan localizations

Public localization and reverse-engineering work around titles including Xenosaga I+II DS, Phantasy Star Nova and Gloria Union, with emphasis on complete playable patches rather than transcript-only translation.

JRPG.WORLD
SpawnMap.ai

Experimental natural-language and image-driven map generation focused on producing playable game maps, including Tactical Ops / Unreal Engine 1 workflows.

spawnmap.ai
Made From Chat

A public umbrella for browser games, tools and experiments developed through sustained conversational AI-assisted iteration, presented as playable artifacts rather than a conventional portfolio of screenshots.

madefromchat.com
CompanionPlay / Tales of Chat

Experiments in portable conversational game context and game-specific generative interaction, extending AI from a chat box into persistent game-adjacent systems.

What ties the work together?

Games, data, preservation and interfaces are treated as parts that can be recombined into working systems.

Bridge separate tools

Emulator + runtime data. Archive + semantic retrieval. Pokémon database + spatial interface. Language generation + playable map pipeline.

Prefer runnable artifacts

The output is typically something testable in a browser, a patch, a live archive, a playable build or a working data tool.

Document the lineage

Public releases, iteration histories and project branches are treated as part of the work, including failed and superseded versions.

Avoid inflated novelty claims

Many components have prior art. The interesting part is often a specific integration or interaction pattern, not ownership of an entire category.
