It's from the game and most likely because you are not using tge same mountings as when you installed the game.

Or he is trying to run the game without having configured it.

I've had configured it but it was still the configuration from the pc (which shouldn't make a difference).

So I tried to delete the configuration file by using "del hocus.sav" and he said "Unable to delete hocus.sav". Then I removed it manually with a terminal and tried to run the setup.exe from DosPad.

After "saving" the settings he said "Run HOCUS to play. Null pointer assignment".

So I guess it has something to do with file access rights after all? But the files should be modifieable from everyone, the permissions are set to 0777 so I can't imagine what the problem could be.

Maybe I'll try the DosPad forum anyway since it seems like an application specific problem (except one of you could give me some more tipps of course 😉 )

Same mountings as on pc should work if the file access is correct for every file and not just the folder

To troubleshoot give us your exact mountings and commands on the pc and the same for dospad

Ok this is embarrassing, I actually overlooked that some of the files in the DosPad folder had only root permissions so it's not wonder it didn't work.

After giving the mobile user access to them it started without any problems though its rather laggy. Setting the cycles to 5000-6000 seems to improve it but its still not that good and any higher values (or max) make it only worse.

I guess its no surprise since its only a beta port to a portable device but to be honest I expected it to be somewhat better.
I'll try some other games and see how good/fast they are.

Glad you figured it out 😉
Dosbox is a demanding emulator, so dospad is as demanding and the ipad is not such a strong device. Coupled wih it being an ARM device performance is expected to be worse than on a PC with the same GHz number ;(
Nothing to be done about it...
