US "Mortality Bytes" version of the game
Current ScummVM git snapshot
This was already mentioned in bug #2772743 ("DW2: Unsupported US version?"), but rather than reopening that one (which was mainly about having to rename files in the US version to get it to run), I'm filing a new bug report.
When running the US version in DOSBox, it shows a "Mortality Bytes" title screen and shows a US flag in the settings dialog. When running it in ScummVM, it shows the same "Missing Presumed..." title screen and UK flag as the UK version. I'll attach some DOSBox screenshots to show what I mean.
Title screen (DOSBox)
Options dialog (DOSBox)
It looks like both of these can be fixed by making sure that _language is set to TXT_US instead of TXT_ENGLISH if the language is Common::EN_USA in Config::readFromDisk(). I'm not quite confident enough about that to make that change without at least discussing it with someone first.
A similar change may have to be made to Config::writeToDisk() as well, I guess.
I don't have the US version to test with, but it seems like only the two methods you list below would need to be changed. I'd suggest that if no one else with the US version comes forward to try making the change, you go ahead and do it, and commit it if it works.
Thanks. I've made the change, and added a note to the NEWS file. Hopefully I'll be able to play through the game before the 1.4.0 release, but right now there's an annoying regression from commit d5690e0. (See note on GitHub for details, though you should already have received an automated mail about it.)
