 ## Emulator
 I have also included an emulator for this system. The emulator supports the following:
 
-* Realtime execution of code (at 4MHz).
+* Realtime execution of code (at ~3.7MHz).
 * Step through disassembled code with labels.
 * Examine CPU and VDP registers, RAM and VRAM.
 * Full support for all TMS9918A display modes. See my TMS9918 emulator here: [github.com/visrealm/vrEmuTms9918](https://github.com/visrealm/vrEmuTms9918)

 This project uses the CMAKE build system to build the emulator and assembler. VSCode works very well with CMAKE, but you can also build manually:
 
+### Windows or Linux
+
 ```
 $ git clone --recurse-submodules https://github.com/visrealm/hbc-56.git
 $ cd hbc-56
-$ mkdir build
-$ cd build
-$ cmake ..
-$ cmake --build . --config Release
+$ cmake -B build -DCMAKE_BUILD_TYPE=Release -S .
+$ cmake --build build --config Release
 ```
 
 The `hbc-56/build/bin` directory will then hold everything you need to run the emulator.

 To test the WebAssembly build, you will need to serve the files from a web server. A simple python http.server will work just fine:
 
 ```
-$ cd bin
+$ cd build_wasm/bin
 $ python -m http.server
+Serving HTTP on :: port 8000 (http://[::]:8000/) ...

 ## Running the demos
 There are several ways to build ad run the demos. They are set up with makefiles, so it is preferred to have [MAKE](http://gnuwin32.sourceforge.net/packages/make.htm) installed and in your PATH environment variable.
