You might combine the --zoom with a smaller --size (if it is not too
much smaller). 800x600 (so double 1600x1200) should be the bare minimum.

Same as qemu vs. qemuw, perl vs. perlw, java vs. javaw. They use
different subsystem flags in the EXE file header.
- When you launch risc from a console window, it will capture the
console, so console output will go to that console and the prompt will
not return while the emulator is running. riscw will, in this
scenario, not capture the console and the prompt will return
- When you launch risc from the GUI, a new console window will be
allocated for it; riscw will not have any console window.
As a consequence, any output or errors that is written by riscw (either
the emulator or the SDL subsystem) to the console will be lost. But the
number of console windows on your screen is greatly reduced.
So I'd suggest to use "risc" with initial experiments with command line
options, and when you know what you need and don't need the output any
more, use "riscw" instead.
Unix based systems (like Linux or OSX) don't have this distinction. When
an application is started from a terminal, stdout will go to the
terminal. When it is started from the GUI, stdout will be lost. You can
have the same behaviour by always calling "risc" from a console window
and "riscw" from the GUI.
