# Portfolio — Android TV Box Rooting + Emulation (SK4 Pro)

## Problem

Turn a UGOOS SK4 Pro Android TV box (Amlogic, Android 14) into a retro-emulation
console — including PS2 emulation via NetherSX2 — which required root, BIOS/ROM
staging, and core configuration.

## Approach

- **Device**: SK4 Pro, Amlogic SoC, Android 14 with A/B partitions.
- **Root**: Pushed Magisk 30.7, generated a `magisk_patched` boot image, and staged the
  patched `init_boot` partition for the A/B slot.
- **Emulation**: Configured RetroArch PlayStation cores (needs BIOS + ROMs), staged
  `scph5501.bin`-class PS1 BIOS and `.bin/.cue`/`.chd` ROMs, and prepped NetherSX2 (PS2)
  with its required PS2 BIOS set (SCPH-39001/70012/77001/90001).
- **Access**: ADB over network (port 5555) + SMB Samba share into `/sdcard` for ROM
  management when the ADB device was still in "unauthorized" state.

## Result

A rooted, emulation-ready TV box with N64/PS1/PS2 paths staged, Jellyfin side-loaded for
media, and a clean ROM/BIOS layout — all managed remotely over the LAN.

## Tools used

Amlogic A/B flashing, Magisk, ADB, RetroArch, NetherSX2, SMB/Samba, Jellyfin.

## Why it's sellable

This is the "hacker" proof — real firmware/boot-image work on Android hardware, not just
app installs. Same skillset applies to ESP32-S3 embedded firmware (I also built a voice
assistant on ESP32-S3). Demonstrates I can go below the OS layer when the job needs it.
