FIIO M3 custom FW ?

[emklap]

Does anyone know if custom fw for the FIIO M3 exist"? with a better font? It has too little memory for rockbox, but there are plenty if tools for decrypting and creating of custom FW.

This web site is one of them, and it has lot's and lot's of information and even an handy UE editor for ATJ soc's with a doc (in Chinese) explaining how to use it. The language can be changed to English by simply renaming the English lan_ENG.dll to lan_CHS.dll and folder NG to CHI.
