Hi, Yes, you can combine various b4ppc libraries (official or not) into one. How? Read below. Download from here MSDN Code Gallery illink.zip and extract it to a folder, lets say c:\illink Download also .NET 1.1 or NET 2.0 (for ilasm.exe) and .NET 1.1 SDK or NET 2.0 SDK (for ildasm.exe) from Microsoft. Install them. Add to your path the folder of ilasm.exe and the folder of ildasm.exe. Now you are ready! Lets say, you have three DLLs. dll1.dll, dll2.dll and dll3.dll and you want to combine them all to MyDLL.DLL. Run the following from the command prompt. c:\illink\illink.exe dll1.dll dll2.dll dll3.dll /out=MyDLL.DLL MyDLL.DLL now includes all the functionality of the three DLLs. Edit: illink.zip attached because GotDotNet site has been shut down.
