After getting TES: Arena to work on my laptop in DosBox 0.74 without a problem, I decided to try it on my iPad's DosPad. After transferring the .zip to my iPad with Google Drive and unzipping using iFile, I ran the 'install' to configure TES Arena. After choosing the recommended sound cards and choosing 'done', a notification says:

Disk is Full. You need at least 0 (0MBytes) free.

If I try running the game after this, I'm stuck at a frozen black screen. Any help is appreciated greatly.
