My version of Discworld 2 (PC DOS/Win purchased in Canada at the time of the original release) does not include the "ENGLISH" TXT, IDX & SMP files. Instead the files are called "US". Renaming them to "ENGLISH1" & "ENGLISH2" seems to work. Also, the background graphic on the title screen is different from the one on the DOS/Windows version.
Tested on:
ScummVM 0.14.0svn (Apr 16 2009 21:28:24) Ubuntu 8.10
Features compiled in: Vorbis FLAC MP3 ALSA zLib FluidSynth
The US version is already meant to be correctly detected, as long as you correctly rename the files to 'us1.*' and 'us2.*'. Are you sure you correctly renamed the files initially?
Renaming the files to us1 & us2 seems to work. I didn't see this anywhere in the docs, so perhaps the wiki needs to be updated.
Main menu graphic is still different. Again, not a big deal and perhaps this was intended?
I presume you mean the title is different, which is correct, in that the US localised version had it's name changed to "Mortality Bytes".
