I compared the exe from dotemu and is the same present in InternationalPatchRepack.exe, thus I remove the link.
About the exe for bel, here is:
That version from dotemu is the same that present in gog, except that gog distributes the exe with the german patch applied (a few bytes, for run the game if your windows country is germany).
The original file name is comandos.exe.If you run this, it says that you need DirectX5. Rename the file to commandos.exe and will run ok.
Thanks carlost800 but this exe didn't help me, same error :/
