For those who are not satisfied with simply upscaling the original low‑resolution textures, AetherSX2 includes a powerful feature. This allows you to replace the game’s original textures with custom, high‑definition (HD) versions, transforming the visual experience.

At the heart of Aethersx3's capabilities lies its Extra Quality mode. This feature represents a significant leap forward in audio processing technology, providing users with the means to dramatically improve the quality of their audio. Extra Quality mode leverages advanced algorithms to meticulously analyze audio files, identifying areas that can be improved or enhanced. It then applies precise adjustments to deliver a more detailed, expansive, and engaging listening experience.

The original PS2 outputted at native resolutions around 480i or 576i, which looks incredibly blurry on modern 1080p or 1440p smartphone screens.
