🔙 A Look Back: The First Version (2024)

Last year, I built a BIOS emulator as a web interface using pure HTML, CSS, and JavaScript.

While functional, it quickly became difficult to manage:

• Code was large and tightly coupled
• UI elements had to be manually hidden/shown based on key presses
• It started behaving like a full SPA (Single Page Application)... just without a framework HAHA

🔁 The Rebuild: Moving to React (2025)

So I decided to rebuild it using React JS.

At first, it seemed simple... until I found myself diving deep into the Phoenix BIOS User Manual (PDF).

From there, it became a 10-day journey of:

• Handling complex keydown events
• Dynamically rendering components based on key inputs
• Improving accessibility and layout with Tailwind CSS
• Managing global state using Redux Toolkit
• And yes — a little help from ChatGPT

Despite the added complexity, the project became far more readable, modular, and maintainable than the original version.
