Hammers of Fate: voice acting and console issues.

Not sure if I posted in the right section, but I hope I did. I used to have a licensed copy of Heroes 5. Now I bought a pirated version with add-ons (couldn't find anything else). The disc contains full games (the add-on itself takes up 4GB during installation). I have some questions: 1. The game has a text translation that is identical in quality to the licensed version, but the voice acting is in English. Where can I find a good Russian voiceover? 2. I played through it and enjoyed it, but a colleague wants to play with cheats. We searched and found a method that involves adding a command to the input and autoexec files, but there are 2 of these files in the game (with the same name and with the "1a" prefix in the names). There were no such problems with the licensed version. How can I fix this? There is also an add-on for the Eastern Tribes, I haven't installed it yet, but I suspect there will be the same problems, and I'm already interested in a solution for those problems as well.
