there is a backup of my internal storage : https://mega.nz/#!RQlHlC4J!MmAWXbXLDbibaLDwFvkbcBgBZ6EHjxLgNT-_cS1aTTYfor adding games on external sd , format it to fat32 , create a ''game'' directory , and put rom on it
here they are. As you can see is a JZ4725B , not sure about the amount of ram tough. It also has a "sd card cartridge" similar to the k1 gba or, more recently, to the rs97 one.
