Alex7GOG: The Windows version of Heroes 1 had several releases. Earliest one has a 16 bit installer, so it cannot be installed on x64 OS and Win7/10. You need to have subsequent CD releases, like Millennium Edition, which has a 32 bit (x86) installer, so the game can be installed on x64 OS.

Otherwise, use Win95/98/Me VM to install game, and copy it onto the host machine

Seraphim5683: So I got Heroes 1 installed and working, using the latest wrapper version. I'm running into the following issues:

1. It will only play music if I use the original CD (Win95 v1.1), using a burned ISO of the same CD gives a "status CD position" error and doesn't play any sound.

2. When using the original CD there is no intro music/sound and no sound effects, looks like it's not reading the contents of the ANIM folder on the CD.

I followed a lot of instructions from this thread, none of which did anything. The CDDA image mounting (are those supposed to be empty by the way?) didn't work either, I made sure the image was in the first optical drive letter... Not sure if I missed anything, any suggestions would be appreciated.

dahbk: I found that for whatever reason the wrapper was not creating config file within the game folder (where i had the copy of the game). It is probably some kind of windows permission issue. That also means, that all game settings, including sound, was not saved. Probably why you did not get the intro music. (I had to change all the settings every time I started the game, including turning on the cd music)

So I copied the 'HEROES' folder from iso image to dedicated game hard drive. Lets say drive E. (16 bit installer from cd image is not working for me)
I deleted wing32 form wing folder and put all the contents form wrapper package right next to game exe.
Now the wrapper was able to create the config file in this new folder 'HEROES' that I copied form cd to the hard drive. Everything works now. Settings are saved and intro music works right form the beginning. Of course, I had to put the game iso in very first virtual drive. However you can change the drive letter in config file now, so this rule might be observed so strictly.

Only problem is that it plays intro every time you start the game and If I try to skip it, it crashes the game.

Diablito: I have HOMM 3 complete from GoG. I've downloaded the Heroes3GL_1.63.exe, put it in the game folder and ran it which made it unzip some dll files etc. However it doesn't appear to be working. F2 when testing does nothing and the game looks like normal.

What did I do wrong and how do I sort this? Thank you in advance :)

AKuHAK: It can be called OPTIMIZED DXWND or lite HD mod for each NWC Heroes series game. Main reason for creating: adding ability for comfort play on modern OS and various bug fixes.
Its not my project, it is from user Verok from old-games.ru

These patches/wrappers redirect legacy DirectDraw graphics into OpenGL 1.1-3.0 and allows play games on modern PC under Windows 10. Added proper windowed mode and several upscale filters for better gaming on modern screens.

This is a wrapper as a replacement for WinG32.DLL for subsequent injections of the game code. The wrapper does not change the screen resolution to game internal and simply expands the image to full screen. It is possible to keep aspect ratio (4:3) or stretch image to full screen.
Added different types of shader filtering. xBRz shader filter was tweaked and added it to the game. Filters from the libretro project were also added later. All shader filters are working on the GPU not CPU. Full list of filters: Bilinear, Bicubic, ScaleNx (x2, x3), Super Eagle (x2), 2xSal (x2), ScaleHQ (x2, x4), xBRz (x2, x3, x4, x5, x6). For each filter except Bilinear and Bicubic there is an opportunity to choose a multiplier and one of two ways of drawing (Bilinear or Bicubic). Accordingly, if the video card supports OpenGL 3.0+, the filters will work, otherwise only linear filtering (Bilinear) will work. Also added vertical synchronization (can be disabled in windowed mode or in config.ini). Settings are stored in the config.ini file in the same path along with the original game.

Added limited support for videocard without OpenGl 3.0 support. Picture will be rendered only with DirectDraw. Shaders will not work. Windowed mode will not work properly. For activating launch game with parameter -nogl.

Now games are portable. All settings are stored in config.ini within game folder.

- Heroes III and Heroes Chronicles
- Heroes IV

Available addons. Note: addons doesnt work without wrapper:
- Built-in manual fix for all Heroes series game except Heroes 4 - just put winhlp32.exe in game folder. If you wish localized version, you can grab it frm localized version of Windows XP
- Music fix for Heroes 2 GOG Windows version - just replace winmm.dll in game folder to make Sound working again

Installation:
- Put dll in the game folder.

Key binding:
- F2 – off/on. frame counter (White)/wrapper performance counter (yellow). This mode is used only for testing the performance of the code, but it is still presented.
- F3 – change shader filter. More options like switching between Bicubic/Biliniear sub-filtering or changing multiplier can be adjusted from window mode (Display menu) or directly inside *.ini file.
- F4 – windowed / fullscreen mode. This combination is already present in the game, just for a reminder
- F9 – keep aspect ratio / stretch to fullscreen

Features:
- Image rendered by OpenGL (it is possible but not reccomended to run game with DirectDraw)
- The game correctly switches from fullscreen to window and back (F4)
- Full screen mode works in desktop resolution
- Added a frame counter to view the performance
- Heavily decreased CPU usage
- Added various shader filters: e.g. xBRz (only if OpenGL 3.0+ is supported)
- Heroes 1: the coloured mouse cursor enabled.
- Heroes 1: added smooth transition between screens like it was in DOS version and Heroes II (with transition from/to castle, hero view, etc.).
- Heroes 1 and 2 (Russian Buka versions): added the ability to play audio tracks in various format including lossless. Supported formats: ".wav", ".flac", ".mp3", ".ogg", ".mod", ".s3m", ".xm", ".it".
- Heroes 1, 2 and 3: smoother hero movement on the map (more frames when moving)
- Heroes 1 and 2 and 3 and Chronicles: Added the ability to play random tracks. To add different options to a track, you need to name those files as well as the original and add something at the end. For example, if we have a track for castle 05-AudioTrack 05.ogg, then his alter versions can be 05-AudioTrack 05_1.ogg, 05-AudioTrack 05a.wav etc. This doesnt work for Heroes 2 GOG version.
- Heroes 2 (Windows GOG Version): if you want music and map editor to work, you need to replace winmm.dll with a newer version from the forum member moranms. Extract from archive oggwinmm.dll, rename it to winmm.dll and replace winmm.dll in the Heroes 2 installation folder. Don’t copy ddraw.dll as GL Wrapper are conflicting with it.
- Heroes 3 and Heroes Chronicles: sounds forced in stereo and sampling rate of 44.1 kHz;
- Heroes 3 and Heroes Chronicles: added lossless pcm WAV support in addition to MP3;
- Heroes 4: works in windowed mode in any game resolution
- In windowed mode added new menu "Patches": For now one patch - "Cold CPU". This patch will increase wrapper speed on weak machines.

Supported games and versions:
These wrappers support all GoG version, languages, releases for Windows platform.
