Windowed Mode Guide

File Location and Changes

• You need to edit the .bat file that launches the game.
• Go to the install location (Right-click game>Manage>Browse Local Files).
• Edit the file “firepx16.cmd”
• I prefer playing windowed as it has less issues for me so remove the -fullscreen and then I increase the scale to 2. Here is what my file looks:

"%~dp0/windows/x16emu.exe" -fsroot "%~dp0game" -prg "%~dp0/game/PLANETX16" -capture -run -scale 2
exit

Additional Options

Full list of commands that I think are relevant to this game.

-scale {1|2|3|4}

Scales video output to an integer multiple of 640×480

-quality {nearest|linear|best}

Change image scaling algorithm quality

• Nearest: nearest pixel sampling
• Linear: linear filtering
• Best: (default) anisotropic filtering

-widescreen

Stretch output to 16:9 resolution to mimic display of a widescreen monitor.

-fullscreen

Start up in fullscreen mode instead of in a window.

-opacity (0.0,…,1.0)

Set the opacity value (0.0 for transparent, 1.0 for opaque) of the window (default: 1.0).
