Nice, ni hao, now i realize i know japanese :D
This "vita remote play" completes all the valid flags for the "first byte" of ATTRIBUTE right ? (wiki is too slow today and i dont remember where is placed)
And this verifyes in some way the order used in the table is correct (is chonologically, but separated bytes are used for similar functions)... e.g: the first byte seems to be for "Multimedia XMB features" (remote play, or XMB ingame modes, one of them with music)
And btw.... because this first byte is completed... if they need to add another "Multimedia XMB feature" it needs to be in another byte... so this way to order them can be changed in the future (probably the last flags of byte 4 will be used as "miscelaneous")
Edit:
btw... the "PSvita" icon is stored inside "explore_plugin_full.rco" (i missed it the first time because all the others are inside "explore_category_game.rco")
And i realized this icon existed (before finding it) because i noticed there is a "youtube" app that uses it in this video (in minute 4:13)
