Thanks to modemakias, i use his apk on sd , the IGO in general run ok, but in each start appears this message: Incomplete folder /sdcard2/Igo_wolrd/license.zip:/ open failed EACCESS /permission denied) but then open normally and works ok. I have this in my sys.txt

[folders]
data_folder_name="iGO_World"
linked_root_list="/storage/ext_sd"

any suggestion will be appreciated. thx
