Tapochka 3D is a PS1 homebrew game developed by nradiowave where you play as an anime-style catgirl trying to escape from a mysterious castle.

From what has been shown so far, the game includes:

• Exploring different areas of the castle
• Solving simple environmental puzzles
• Rescuing fairies trapped inside cages
• Collecting keys to unlock new paths

At the moment, there isn't much information available about the project. Most of what we know comes from updates shared in 2025, and there haven't been many recent development posts. Hopefully, the project is still active, because it certainly looks like a charming addition to the PS1 homebrew scene.

If you'd like to learn more, we've gathered everything currently known about the project in our article:

Tapochka 3D

It all started with a simple question: “Is it possible to build a game for the PlayStation One using Unity?”

My initial research showed that the answer was technically “yes,” but the process was extremely complicated. So I decided to take a different path and build my own engine capable of exporting projects to the PSOne.

Today, I reached what I can call the first MVP of that idea. For the first time, I managed to complete the entire pipeline — from creating a simple cube in the editor to running it in a PlayStation One emulator.

Of course, this is not a full-fledged game engine yet. But as a foundation, it’s a very promising start. Along the way, I also had the opportunity to learn a lot of fascinating details about the original PlayStation hardware and development process.

There’s still a long road ahead, but seeing that first cube appear on the PSOne screen made all the effort worthwhile.

El desarrollador Elias Daler anunció un par de meses uno de sus proyectos más interesantes: un juego en 3D basado en Serial Experiments Lain para el original PlayStation. Para el que no lo conozca, es conocido en la comunidad por haber hecho un port de Yume Nikki para la PS1.

Por ahora, el alcance del proyecto es aún desconocido (podría quedarse en una simple demo con unas pocas salas), pero lo que se ha mostrado ya resulta bastante interesante. En esta fase temprana, el escenario principal es la mítica habitación de Lain, recreada con su ordenador, su cama y los distintos objetos que aparecen en la serie.

En el apartado técnico, el desarrollador ha estado trabajando en el modelado de Lain, especialmente en su rostro. La mayoría de objetos del entorno están realizados mediante color por vértice (vertex color), mientras que algunos elementos concretos utilizan texturas.

Aunque todavía hay muy poca información sobre la totalidad del juego, se trata de un proyecto especialmente llamativo para los fans de Lain, del anime en general y del homebrew de PS1.

¿Qué os parece? ¿Os gustaría probarlo?

Developer Elias Daler announced a couple of months ago one of his experimental projects: a 3D game based on Serial Experiments Lain for the original PlayStation. Right now, the scope of the project is still unclear (it could end up being just a small demo with a few rooms), but what has been shown so far is already quite interesting.

At this early stage, the main environment is Lain’s iconic bedroom, recreated with her computer setup, bed, and various objects seen in the anime. On the technical side, the developer has been working on Lain’s character model, especially her face. Most of the environment is built using vertex coloring, while some specific elements, like the face do use textures.

Even though there’s still very little information about the final scope, this is already a very intriguing project for fans of Lain, anime in general, and PS1 homebrew.

What do you think about it? Would you like to see this idea expanded into a full game?

Here you have the full article (also in Spanish) with more information about the project:

New Serial Experiments Lain on PS1

Por muy increíble que parezca, la verdad es que sí que hay alguien haciendo ese proyecto. El usuario T0fuZ está creando un motor gráfico donde puedes meter los personajes, objetos y escenarios de todos los RE de la PS1 y crear tu propio juego funcional en la PS1 original. De momento solo lo puedes probarlo si te unes a su Patreon. De todas formas, tenéis un montón de videos diarios en su canal para ver como evoluciona el proyecto.

De todas formas, os voy a comentar un poco todas las novedades que nos ha dado en mayo para que veáis la rápida evolución del proyecto. Solo en un mes ha introducido las siguientes características:

• Ahora se pueden meter las bandas originales de cada juego.
• Los enemigos tienen IA y puedes poner varios bosses a la vez.
• Ahora hay armas y sonidos.
• Ha optimizado el cambio de cámaras y la CPU tiene menos trabajo.
• Incluso ha metido un sistema cooperativo para dos jugadores (os imagináis jugar al RE1, 2 o 3 con un amigo?)

No sé qué pensáis, pero me parece un proyecto increible. Ojalá siga lanzando más actualizaciones y podamos ver la versión final. El desarrollador ha dicho que su objetivo es lanzar el motor personalizable para todo el mundo y él mismo quiere crear otro juego (con sus propios assets, escenarios y sonidos) para lanzar un nuevo survival horror para la PS1 original en pleno 2026/2027.

Qué te parece que se sigan lanzando juegos en la PS1 a día de hoy?

In just a few weeks, u/t0fuzzer has done an incredible amount of work updating his PS1 engine, adding a huge number of new features. For those unfamiliar, he is developing an engine where original Resident Evil PS1 assets can actually run natively on PS1 hardware. We’ve written a detailed article on our website tracking every single update based on the dozens of videos he has been uploading. In this article, we cover all the progress made during the month of May. We will soon also release a continuously updated article covering all June developments day by day.

We think this is an absolutely incredible project and we really hope it continues to evolve!

Over the past month, Green Herb Engine has gone from an early experimental build to one of the most advanced PS1 homebrew engine projects currently in development.

The engine can now render full environments from Resident Evil, play original music and sound effects, and handle lighting systems inspired by the original games. It also includes classic tank controls and fixed camera transitions, recreating the core survival horror feel on PS1 hardware.

One of the most impressive aspects is how many original assets are already working in-engine. Characters, enemies, and environments from Resident Evil 1, 2 and 3 are now being loaded and tested in real time, including iconic enemies like the Tyrant and Nemesis appearing in the same scenes.

Throughout May, the developer also introduced major technical improvements such as:

• Optimised camera switching with near-original performance
• Native playback of original RE soundtrack files
• Reverb and environmental audio effects
• Improved enemy AI with reduced CPU usage
• A fully working mask system for correct 2D/3D layering
• Support for multiple characters on screen at once
• Co-op concepts

The most recent updates even show experimental scenarios with multiple bosses on screen simultaneously, something that would have been unthinkable on original hardware without serious optimisation. While still clearly in active development and requiring emulator enhancements like expanded RAM, the progress so far is already remarkable.

We go into full detail, including all videos and technical breakdowns, in our article here (you can also read it in Spanish):

The Engine That Could Bring a New Resident Evil to PS1

Para los Flappy Adventure: X y 3

Cualquier duda me podéis escribir por aquí :)

Feliz sábado!

As part of Flappy Week PSX, we’ve published the second part of our interview with Juanmv94, focusing on the development process behind Flappy Adventure X and Flappy Adventure 3.

Here are some highlights from this section:

• What was the most satisfying moment while making Flappy Adventure X?
• Which of the minigames (Arkanoid, Tetris or Space Invaders) was the hardest to implement?
• If you could remake Flappy Adventure X today with your current experience, what would you change?
• What was the most difficult thing to program?
• Was there any mechanic that initially seemed like a good idea but that you eventually had to remove during development?
• What was the biggest hardware limitation during development?

This part of the interview focuses much more on the creative and technical decisions behind the games, including level design philosophy, minigame implementation, visual choices, and hardware limitations.

If you’re interested in PS1 homebrew development, this section gives a deeper look at the real challenges behind building a full game on original hardware.

Like the previous one, this interview is also available in Spanish. We’ve started a new initiative to support multilingual articles on our website. If you are interested in translating one or more articles into your language, feel free to send us an email or message here!

If you are interested in read Part 1, you have it here:

Origins of Flappy Adventure

Today we published our very first developer interview on PSX Homebrew Games, featuring Juanmv94, creator of Flappy Adventure X and Flappy Adventure 3 for the original PlayStation.

In this first part, we focus on the origins of the Flappy Adventure series and Juan’s personal connection with the PS1.

We talk about:
• His favourite PlayStation games
• How he learned PS1 development
• His previous experience creating Game Boy homebrew projects
• Why Flappy Bird became such an important character in his projects
• The evolution from the original Flappy Adventure to FAX and FA3
• The origins of the Angry Birds references and rivalry
• Funny details and inspirations behind the games

We also wanted to announce something special:
This is officially our first multilingual article, available both in English and Spanish.

It’s something that genuinely makes us very happy because we know there is a huge Spanish-speaking PS1 homebrew community, and we want these interviews and articles to be more accessible to everyone.

Tomorrow we’ll publish Part 2, where we will focus much more deeply on the technical side of the projects, including engines, optimisation, level design, PlayStation limitations, and much more.

We hope you enjoy it :)

Good luck... and have fun!

As part of Flappy Week, we’ve published an article covering Flappy Adventure 3, the most ambitious entry in the series by Juanmv94.

What starts as a simple objective, collect coins to satisfy Flappy’s girlfriend, quickly evolves into a full-scale 3D platforming adventure filled with humour, exploration, and unexpected twists.

The game introduces a completely new progression system:
• Flappy begins unable to jump at all.
• Collecting coins unlocks and upgrades his jumping ability.
• Movement and exploration on 3D worlds become key to progression

Players can explore 5 distinct themed levels, including Flappy’s hometown, two city maps, a TikTok-inspired stage and Minecraft-themed world. Each level has its own identity, soundtrack, and gameplay situations.

Flappy Adventure 3 also features:
• Checkpoints that save progress and collected coins.
• Environmental hazards, traps, and instant-death pits.
• Fully unlocked level selection from the start.
• English and Spanish voice acting with different humour styles.
• Solid performance across large 3D environments.

We also dive into several developer curiosities. If you are interesed in know more about them or the game in general, you can check out the article here with download links:

Flappy Adventure 3

As part of Flappy Week, we’re also featuring Nortis, a Tetris-inspired PS1 homebrew puzzle game developed by Jimmy Breck-McKye (u/yojimbo_beta) using PSNoobSDK.

🎂 Happy birthday to Jimmy! We’re really happy to feature Nortis during Flappy Week and hope you have a fantastic day :)

About the game, at its core, Nortis takes the familiar block-stacking formula and strips it down to its purest form: no music, no sound effects, and no external distraction. Just gameplay and decision-making.

The game challenges players to:
• Stack falling pieces to clear horizontal lines
• Survive as the board gradually fills up
• Adapt to increasing pressure caused purely by mistakes rather than a difficulty curve

One of its most unique aspects is its fully random piece system:
• No preview of upcoming pieces
• No pattern or predictability
• Pieces can repeat multiple times in a row completely at random

This makes every decision significantly more tense, as planning ahead becomes almost impossible.

We also take a look at the development approach behind the game, including its use of modern tools for PS1 homebrew development and a C-based workflow designed for the original PlayStation hardware.

A minimalist but highly interesting entry in the modern PS1 homebrew scene, now covered in our full article 👇

Nortis PSX

As part of Flappy Week, we’ve published an article dedicated to Flappy Adventure X, one of the earliest PS1 homebrew projects developed by Juanmv94.

At first glance, it presents itself as a 2D precision platformer inspired by Flappy Bird, but the game quickly reveals a much deeper and more unusual design:
• Fully 3D environments.
• 6 progressively challenging levels.
• Instant-death mechanics based on flying and collision rules.
• Environmental hazards such as burning zones or flaying floor tiles.
• The game includes enemies as the yellow bird from Angry Birds, Chuck.
• Hidden secrets and optional advantages
• And unexpected minigames like Tetris and Space Invaders integrated into main levels

The game also features a strange and surprisingly storyline, where Flappy’s desire to become friends with the Angry Birds leads him to an obsession with reaching the end of the “Pipe Forest”, ultimately causing a chain of events that affect his personal life in unexpected ways...

Designed as a highly demanding experience focused on precision, timing, and patience, Flappy Adventure X encourages careful play and exploration, rewarding risk-taking while punishing mistakes harshly.

We’ve now covered all gameplay systems, mechanics, story elements and curiosities in detail in the full article:

Flappy Adventure X

On May 17th, we launched a small community challenge to try to guess the two PS1 homebrew games that would be featured during our upcoming online event starting on May 25th. After many guesses, theories, support messages, and some surprisingly close attempts… we finally have a winner.
