Konami has updated its video submission guidelines.

Videos can be uploaded to X (Formerly Twitter) and Discord now for Japanese streamers.

With one exception:

Japanese streamers and fans can only share screenshots of “Yu-Gi-Oh! Duel Monsters GX Tag Force” (PSP) to X and Discord. This restriction doesn’t extend to “Yu-Gi-Oh! Duel Monsters GX Tag Force Evolution” (i.e. Yu-Gi-Oh! GX: The Beginning of Destiny) for the PS2.

No reason was given as to why, but on a strictly editorial note, the original PSP release of the game included the theme song “99%” by Bowl. The PS2 release does not include the song, instead using a sound-alike song.
