If you select black from the interface style, a WM-W800 style theme will be selected, echo light style for white and echo dark style for gold.
The reason why the direction of the cassette tape is reversed is that the original Walkman is in this direction.
_r3c is Rivision3c.
Fixed the cover screen of the dark theme and the player screen of echo white.
Please change the file name appropriately.
