HDMI options

Modern flat-panel televisions handle the console's native analog signal poorly, often adding lag, soft scaling, or refusing the 240p signal entirely. Converting to HDMI solves this by producing a clean digital output that any modern display accepts. There are two broad approaches: external scalers and integrated solutions.

External scalers

An external upscaler takes the console's RGB or S-Video output and converts it to HDMI in real time. The RetroTINK family is the most popular choice, offering low latency, accurate scaling, and processing options such as scanline emulation. You feed it a good analog signal, ideally RGB, and it does the rest. The quality of the result still depends on the cable feeding it, so pair a scaler with a proper RGB cable.

Integrated / cartridge solutions

The Mega SD flashcart includes an optional HDMI output, letting it drive a digital signal directly from the cartridge slot while also serving as a game loader. This is convenient because it combines two upgrades in one device, though it ties your video path to that cartridge being inserted.

Internal HDMI mods

Some enthusiasts install board-level digital mods that tap the video signal before it is converted to analog, producing HDMI with no quality loss. These require soldering and are the most involved option.
