I can successfully add these files to ScummVM running on my computer. Both devices are running version 2.1.1, though they have different build dates. I also tried downgrading the iPad version to 2.1.0, but it didn't make a difference. I have verified that the files in question have the same MD5 hashes on both devices, so it's not an error copying the files over.
iPad specs:
- iPad, 7th generation
- iOS 13.4
- ScummVM 2.1.1 (built Jan 19 2020 21:03:31)
- Downloaded from scummvm.org, IPA version
- Arch Linux, kernel version 5.5.9
- ScummVM 2.1.1 (built Feb 15 2020 23:23:06)
- Installed from official Arch Linux package repo
Anyone have any ideas why I'm not getting consistent behavior between the two versions?
