Re: How long does testing of PongL.asm should usually take?
If you load your Computer.hdl into the HardwareSimulator, you can load a .hack file into the ROM (folder icon) and see the asm commands for the binary instructions.
You can also load .hack files into the CPUEmulator and view their asm commands there. You can also run them in the CPUEmulator. Load your generated Pong.hack file and you should be able to play the Pong game, but it may run rather slowly. On my laptop it takes 5-6 seconds before the paddle and ball appear.
