Meh

According to NVIDIA, these titles are still improved to 1080p.

Original:

《塞尔达传说 黄昏公主》的 NVIDIA SHIELD 版本不仅仅包含了原作中的所有元素，更是提升了画质并支持 1080p！

Translation:

The Zelda Princess Twilight version of NVIDIA SHIELD not only includes all the elements of the original, but also enhance the quality and support 1080p!

Like the Wii U version then.

It’s been updated as a developer of the shield came forward to say that the my ARE ports running natively.

The blurb was incorrect.
