Recently I manage to find a way to put back achievement support in my port Classic RBDoom 3 BFG . In order to enable this you must first download the Open Platform binaries with Steam form here . Extract the dlls or so file that you need and put OpenPlatform.dll on the game's base directory and the steam_api on the directory where the executable is. After that create a steam_appid.txt and type DooM 3 Essential Overhaul HD Pack v2.0 also includes all the fixes for materials from Resurrection of Evil in the original campaign. Moreover, it adds the shotgun sound from the BFG Edition and 1) truned on 7.1 surround sound on headphones connected via USB (some 7.1 headphones profile); 2) executed "Doom 3 BFG edition"; Result: 3) game executed fine, yet . silence; Solution: 4) I changed profile of my USB headphones to so called "FPS" and . sound in a game appeared, problem fixed. Basic solution for any headphones connected to Doom 3 BFG Edition is an updated version of the cult shooter Doom 3, as well as an addition to it called Ressurection of Evil. In addition to the familiar Doom 3 story, BFG Edition includes new episodes – seven levels under the general heading The Lost Mission. Překlad Doom 3: BFG Edition byl dokončen a hru si nyní můžete všichni zahrát s českými titulky. Čeština do velmi dlouho očekávané hry je tu a vám Doom 3 BFG Edition meanwhile has Doom 3, both of it's expansions, and Doom 1 and 2. Doom 1 and 2 wads are pretty good (Although a bit cencored - the wolfenstein levels are gone, and the med packs got a different look). For successfully first time run the game it is necessary to inser into startup argument>. +set r_DisplayDeviceID "1". After this the game launched for the first time and created config folders in windows Save Game folder. Than you can configure options in D3BFGConfig.cfg file. If you say interaction.vfp and test.vfp should work for Doom 3 BFG too, then all I need is where to put them. I installed the texture pack the same way OP suggested, inside the D3BFGHR folder within the game's main folder \Doom 3 BFG Edition. And all the textures show up in the game, so I installed them correctly. Lm8Nn.
