What is the Totoro album art? Is it the album art to one specific album named totoro or what? which build do you use? Which wps are you using? Be more specific about your questions!
Best post a screenshot (it's called screendump in rockbox) of what you see with the following instructions: To enable the screendump, select Menu->Info->Debug (keep out) ->Screendump. Then connect the player via USB and an image of the screen will be "dumped" to the root directory of the Rockbox unit instead of connecting to your computer. If the unit has RTC (real-time clock), the files are named "YYYY-MM-DD HH-MM-SS.bmp" (YYYY=year, MM=month, DD=day, HH=hour, MM=minute, SS=second). Otherwise, they are numbered sequentally, dump_0001.bmp etc. To disable the screendump afterwards, select it again in the Debug menu.
