Retro Gaming

Tools that keep older hardware, games, and multiplayer communities useful on modern setups.

04Community / Scheduling / Web

PS2 Online Calendar

A scheduling hub where PlayStation 2 players can post sessions, find upcoming matches, and keep the console's online multiplayer scene connected.

PS2 Online Calendar addresses a basic problem in retro online gaming: active servers and communities exist, but players are spread across different groups and schedules. The calendar gives them one place to announce and discover upcoming sessions.

It is designed as a straightforward, welcoming community tool for players of all ages—useful whether someone is organizing a full event or simply checking what people plan to play tonight.

  • Post and browse scheduled PS2 game sessions
  • Built specifically for the surviving PS2 online scene
  • Simple community-first interface
  • Public web application
06C / Emulator plug-in / Windows

1964 RetroAchievements Support

An unofficial plug-in that adds Casual-mode RetroAchievements to GoldenEye 007 and Perfect Dark in 1964 GEPD Edition.

This experimental community plug-in brings RetroAchievements to the mouse-and-keyboard-focused 1964 GEPD Edition while preserving its original mouse injector. It supports GoldenEye 007 and Perfect Dark on Windows.

The release is intentionally Casual mode only: Hardcore mode and other Nintendo 64 games are not supported. Users must provide a clean 1964 GEPD installation, their own legally obtained ROM, and a RetroAchievements account.

  • GoldenEye 007 and Perfect Dark achievement support
  • Preserves 1964 GEPD mouse-and-keyboard controls
  • Replaces stored passwords with a login token after authentication
  • Detailed installation and troubleshooting documentation
08Python / Raspberry Pi / Recording

RetroPie Recording System

An offline controller-operated recorder for Raspberry Pi 4 RetroPie that captures 720p gameplay and clean stereo audio without a capture card.

RetroPie Recording System records the Pi's full composed display at 1280×720 and 30 FPS using Raspberry Pi 4 hardware H.264 encoding. That approach also captures hardware-rendered libretro cores such as Flycast on its supported setup.

Recording starts and stops from a configurable controller shortcut. The system provides in-game notifications, organizes files by system and game, checks free space, and safely finalizes a recording when the player exits a game.

  • Controller-operated start and stop controls
  • 720p/30 FPS H.264 video with stereo game audio
  • Automatic folders, filenames, and exit-time finalization
  • Fully offline with no telemetry, accounts, or cloud services
