solaris, Sorry it is not possible to correct firmware that display flipped or rotated as they are designed for players with specific componenets that require this to happen. Whilst you can extract the images with s1res and manually flip or rotate them within an image editing program you can not change there positioning or the position of text so everything will be out of alignment. This link to s1res works fine for me.
