Please read the instructions in the official RockBox for FUZE manual.


The display of the FUZE has 220x176 pixels and therefore the same dimension as the iPod Color/Photo or the iRiver H3xx.


Use the rbutil to generate .voice files. Then open the file .rockbox/langs/english.voice (or whatever language you just created) up in a hex editor and change the Byte at position 0x07 to 0x35 = 53d, the target ID of the Fuze. Now it should be recognized. You can find all target IDs in the rbutil.ini.
