It's impossible to know exactly what r4iSDHC it is. There are numerous clones with the same name.You can try the R4iRTS/SDHC from http://www.r4rts.com/download-en.htmJust remove any existing files/folders with the same name and replace them with the new ones.In order to play mp3 files you need moonshell, which is included IIRC.
