CINE: Operation Stealth Amiga US version not starting

[fxgogo]

Operation Stealth Amiga US version not starting and generating an error.
ERROR: Cannot open file errmess.dat for reading!
ScummVM version 2.1.3pre1-ge2a851b964
Host OS: Windows 10 64bit 1909 Build 18363.1016
Game version: English, USA, Amiga floppy

Bug details:
I have a folder with all three floppy disks from Amiga US version.
Create a new game in ScummVM. Point to the folder.
ScummVM recognises Amiga version. Not changes are made to settings.
Start the game, after warning of build version, I get the above error.

I have a folder with all three floppy disks from Amiga US version.

@fxgogoCould you please download md5deep from ​​http://md5deep.sourceforge.net/
and then run the following in the directory where you have the game data files
for your version of Operation Stealth and give the output here into this ticket:

echo The listing of files:
dir
echo MD5sums of the first 5000 bytes of each file:
md5deep -p 5000 * | find /i "offset 0-4999"
echo MD5sums of the full files:
md5deep *

The idea is to get the file sizes and names using "dir" command,
the MD5sums of the files' first 5000 bytes by the second command and
the MD5sums of the whole files by the third command. Are you sure
there is no errmess.dat in any of the source floppies?

Thank you!

I can go back to the floppies rather than the ADF's I made to double check.

Thanks for the file information you provided. It would be good to know if errmess.dat exists on the floppies or not. All the errmess.dat files that I've come across in different Operation Stealth versions are 1440 bytes in size.

Here are some MD5sums of errmess.dat files I've seen:
230abf113fcd9df6f466b4c138dfb687 German release
6b3b7099f48c561065afbac7a42d446d US release (Protagonist is named James Bond)
ab02342d5b89b1a3998eb32f2eca112a English release (Protagonist is named John Glames)
c82b927fa7c7a5604fa9dc297bcf6794 French release

You can even try to open files near the size 1440 bytes in a text editor to see if it contains text. The errmess.dat is a file containing text (With lots of trailing zeroes in between strings) like for an example:

You haven't noticed anything special.
Nothing interesting.
Nothing to say about it.
You find nothing.
Let's forget about it.
I could if I wanted, but I don't.
There are so many things to take and you want this one!
No need.

Waiting for this ​pull request to be merged. If it is merged it would make Operation Stealth work even without the ERRMESS.DAT file by using default error messages as a fallback. Let's see...

The pull request was merged. Now your version should start and the error messages should be ok even without the ERRMESS.DAT. If you have it, great, if you don't, it'll fall back to the default error messages that are now included in the ScummVM's source code.

[karisal]

I'm closing this ticket as fixed because the problem is gone. @fxgogo If you happen to check out your original floppies would you please leave a comment here whether errmess.dat or some other 1440 bytes sized file exists on them? But if you don't, no worries, it should work without it now anyway.

[fxgogo]

Hi Karisal, so I can confirm the game is working now. I will start playing it properly to check for bugs now. I have also attached the disk contents as jpgs. They come directly from my Amiga 1200.

Ok, thanks for the info! It looks like errmess.dat is not on the original floppies. But, it works without it now so it's ok.
