How do I load a GBA ROM in IodineGBA?

You need to handle ROM loading manually via JavaScript, such as using an HTML input element to upload files or fetching them from a server, as the emulator itself doesn't provide built-in ROM management.

Does IodineGBA support save states?

No, the project focuses on core hardware emulation and likely doesn't include save state functionality. For game progress, you'd need to rely on in-game saves or implement custom storage solutions.

IodineGBA vs other web GBA emulators: which is better?

IodineGBA is a pure JavaScript solution that runs directly in browsers without plugins, making it easy to deploy. However, alternatives like emscripten ports might offer better performance or more features, so choose based on your needs for accuracy versus simplicity.

Can I use IodineGBA on mobile browsers?

Yes, it should work on modern mobile browsers that support HTML5 and JavaScript, but performance may suffer on older devices or with graphics-intensive games due to JavaScript limitations.

How to improve audio latency in IodineGBA?

Audio latency can be minimized by optimizing Web Audio API settings or synchronizing with requestAnimationFrame, but this requires advanced JavaScript knowledge and isn't covered in the documentation.

Is IodineGBA compatible with game controllers?

Out of the box, it probably only supports keyboard input. Adding controller support would require integrating the Gamepad API, which isn't mentioned in the README and would need custom implementation.

Complete Hardware Emulation

Accurately replicates the GBA's CPU, graphics, and sound systems for a full emulation experience, as stated in the project description and key features.

Educational Value

Serves as a practical example of low-level system emulation in JavaScript, ideal for developers studying web technologies and retro hardware, per the philosophy section.

Accessibility

Makes retro gaming instantly accessible on any device with a modern web browser, lowering the barrier compared to desktop emulators, as implied by its browser-based nature.

Cons

Limited Feature Set

Lacks advanced emulator features common in desktop alternatives, such as save states or screen filters, which are not mentioned in the README or key features.

Performance Constraints

JavaScript execution in browsers can lead to lag or stuttering on lower-end devices, especially with demanding games, due to the overhead of web technologies.

Sparse Documentation

The README provides minimal guidance on setup, integration, or troubleshooting, which could hinder new users from effectively implementing the emulator.
