MaxChiron:This video is from a Korean YouTuber who is contributing to remaster low definition pieces in 80'/90', especially those classics born in Japanese golden ages. His/Her works includes upscaling the definition and upfps with AI techniques. These works will exhaust so much time and expensive hardwares. Thanks to him/her for these splendid remasterpieces and if u like these jobs, here is his/her home page on youtube, in case you my friends in the mainlad, can visit it in your own ways.
