CnCNet for Ares
2+
================================================================================
3+
4+
Spawns Yuri's Revenge and connects players through cncnet5. This project should be used in conjunction with the [xna-cncnet-client](https://github.com/CnCNet/xna-cncnet-client) and [Ares](https://launchpad.net/ares/+download)
5+
6+
### Usage
7+
- Place cncnet5.dll in you mod folder with the xna-cncncet-client and the Ares files.
8+
- Optionally place rename.dll in the mod directory.
9+
- Syringe from Ares will automatically detect and include cncnet5.dll.
10+
- Configure xna-cncnet-client to execute Syringe.exe rather than game(md).exe
11+
12+
### Building
13+
- Download cncnet-for-ares
14+
- Edit src/rename.c, change the strings for the Gane name and file locations. Do not exceed the size of the existing strings in the game.
15+
- Download [win-builds](https://downloads.cncnet.org/win-builds-for-patching.zip) and install it by double clicking win-install.bat
16+
- In the cncnet5-for-ares run build.cmd by double clicking on it. Read the output window any errors you may introduced.
17+
- You should now have rename.dll. Now you can rename rename.dll to something appropriate for your mod (the name will not stop it from being loaded by Syringe).
18+
19+
20+
### Caveats
21+
- Source code for cncnet5.dll is not public, only the cncnet5.dll file is provided here.
22+
- You do not need to use the command line -SPAWN argument.
23+
- You may need to edit build.cmd if win-builds did not get installed into C:\win-builds-patch-32\
