PCL-FE

Project Overview

PCL FE is maintained by paopao340 as a fork of PCL2, a modified Minecraft launcher written in VB.NET and WPF and targeting .NET Framework 4.8. It keeps the original interface and animations, builds Terracotta multiplayer into the launcher so hosting a room yields a code like U/XXXX-XXXX-XXXX-XXXX without port forwarding, and fixes the Authlib-Injector and Microsoft login flows. Dynamic video wallpapers were removed, leaving only static ones.

Item	Value
Version	1.3.5, VersionCode 436
Platform	Windows 10 / 11
Stack	VB.NET + WPF, .NET Framework 4.8
Projects	PCLPro/, PCLCS/, MeloongCore/
Distribution	A single EXE, runs portably

A PCL2 fork that keeps the original feel while fixing multiplayer and external login.

Key Features

• Built-in Terracotta: the multiplayer page hosts a room directly and shows a code like U/XXXX-XXXX-XXXX-XXXX, with the module pulled from the Terracotta_Module.zip asset
• External login: drop an authlib-injector:yggdrasil-server: address into the window to set the auth server and fill in the register URL
• Microsoft login fix: the OAuth Client ID is injected through PCL_MS_CLIENT_ID and never stored in the repository
• Textures and wallpapers: texture downloads fall back to alternate lines, and map screenshots can be set as static wallpapers
• Version isolation: the PCL2 instance model is kept, and isolation turns on automatically when a version folder contains mods or saves
• Single-file build: the output is Plain Craft Launcher Fork Enhanced.exe, which runs as a portable build

Interface and Controls

• Home layout: left-hand navigation switches between launch, download, multiplayer and settings pages with the original card styling
• Multiplayer page: shows the room code and online members, and checks Terracotta-related Windows firewall rules before hosting
• Instance page: manages mods, saves and resource packs per isolated version with shortcuts to their folders
• Drag and drop: dropping an Authlib address or a modpack into the window starts the matching flow
• Settings: login method, download source, Java list and memory allocation are adjusted on one settings page

Target Audience

• Minecraft Java Edition players
• Players who host multiplayer rooms
• Users of external auth servers
• Developers building a modified launcher

Quick Start

1. Run PCLFE_1.3.5.exe directly on Windows 10 / 11, no installation needed
2. Check the Java list in settings, where detected runtimes are scanned and sorted
3. Install a game version from the download page and wait for libraries and assets
4. Open the multiplayer page, host a room and share the U/XXXX-XXXX-XXXX-XXXX code
5. For external login, drop authlib-injector:yggdrasil-server:<address> into the window

System Requirements

Item	Requirement
OS	Windows 10 / 11
Runtime	.NET Framework 4.8
Build environment	Visual Studio 2022 with .NET desktop and VB workloads
Game dependency	A Java runtime for launching Minecraft

Notes

• Keys stay out of the repo: Microsoft login and CurseForge need the PCL_MS_CLIENT_ID and PCL_CURSEFORGE_API_KEY environment variables
• Wallpaper limits: only static image wallpapers are supported, with no dynamic video wallpaper
• Multiplayer depends on the service: room codes are issued by Terracotta, so hosting fails when the service is unreachable
