The main page states that the compiler IL2CPU compiles IL to x86 code utilizing NASM. So IL2CPU translates c# code into x86 assembler? Why not translate c# code into C and then use gcc (rather than nasm) to build native binaries? That way you get support for x64, arm, ppc, etc.

Also lots of confusing answers:

Can I use Delphi.NET? Maybe. Unfortunately the Delphi libraries for full of P/Invokes. If you only use the .NET libraries, and use the .NET 2.0 version it might work. Alternatively, you could use Chrome.

Are they talking about Chrome, the browser here? ??

Also why do you need the non free version of Visual Studio? "To further the features of Cosmos development we rely on extending Visual Studio" Why??
