Pikachu Animated Boot Sequence

Overview

Pikachu Animated Boot Sequence (authored by Ao Jiao Xiao Zheng Tai) is a high-energy visual customization module that replaces drab manufacturer boot logos with a fluid, 60 frames-per-second animation of Pikachu unleashing electric lightning sparks.

Technical Architecture & How It Works

1. Structure of /system/media/bootanimation.zip

The animation uses standard uncompressed (STORE mode) zip structuring required by the Android bootanimation binary:

bootanimation.zip
├── desc.txt          # Configuration: 1080 1920 60
├── part0/            # Introduction frames: Pikachu charging electricity
└── part1/            # Infinite loop: lightning spark oscillation

2. Execution Pipeline

1. Kernel Init: The Linux kernel boots and mounts rootfs and vendor partitions.
2. Overlay Mounting: Magisk/KernelSU mounts the custom bootanimation.zip over /system/media/bootanimation.zip.
3. SurfaceFlinger Launch: /system/bin/surfaceflinger starts and triggers /system/bin/bootanimation.
4. Playback: The binary reads desc.txt, pre-loads frame textures into GPU memory, and renders them at 60 FPS.
5. Handoff: Upon sys.boot_completed=1, the animation stops and Android SystemUI keyguard appears.

Installation & Verification

Flash pikachu-boot-animation-v1.0.zip through your preferred root manager and reboot to enjoy the animated startup visuals.
