    As you know, Google blocks writing to SDCard since KitKat. In android 5 Google added new functions which helps to communicate with this storage. It was necessary to rewrite the emulator and it must use these functions. Unfortunately Google does not provides all necessary functions – only small set. Due this issue were added various workarounds which needs to be tested.

    Please, if you want help with testing, just send me email.

    What you need ?
    1. Device with Android 5

    2. Secondary SDCard. It’s not recommended to use the primary SDCard for testing until all bugs will be fixed. Or data backup must be made. Simply said – put another sdcard (without important data, or empty) in the slot.


    How it works?

    Start Global Settings and scroll down to section “SDCard and storages”. Android 5 gets new options “SD-Card permissions”. Under the title is button “Request permissions”.

    This button calls standard android folder picker. In this picker switch to sdcard and pick folder where are your MS-DOS games and pick. After that your system allows to Magic Dosbox write access to this folder. This directory can be mounted like Drive C:\ now.

    You can set access to whole sdcard, but this is strongly not recommended. It’s good to test this variant too, but please really backup your sdcard, or use another sdcard.

    You should see picked path under the “Request permissions” button. If not, something is wrong – please report.

    On earlier Android 5 versions happened that if the SDCard was without title then this picker caused crash. Title can be added during sdcard “format” phase. But this will delete whole sdcard, so beware.

    After that, you will be able pick this special path in file manager. For example if you want set Drive C:\ in game profile. The special path is green colored.



    Works for me… haven’t had to change anything, maybe because i’m rooted anyways.


    Yes, that could be;) This fix is for not rooted devices which has blocked write access for 3rd party apps.
