Options

; {{anchor|--aspect}}<code>--aspect=<w:h></code>
: Specify screen aspect ratio. The default is the Progressive Scan Mode system setting (4:3 or 16:9).
: Setting this option to 3:2 is not recommended unless interpreting 720×480 as square pixels.
; {{anchor|--offset}}<code>--offset=<x:y></code>
: Set offset. The default is the Screen Position system setting (-32 to +32).
; {{anchor|--zoom}}<code>--zoom=<x:y></code>
: Set zoom (default: auto).
; {{anchor|--zoom-auto}}<code>--zoom-auto[=<ratio>]</code>
: Enable best fit for a given screen size ratio, or [[wikipedia:Safe area (television)|safe area]]. The default is the Game Boy Player Start-up Disc's Screen Size setting (0.75 or 0.875).
; {{anchor|--rotate}}<code>--rotate=<0-359></code>
: Set rotation (default: 0).
; {{anchor|--poll}}<code>--poll=<0-11></code>
: Set controller polling rate. Use if your third-party controller or controller adapter is malfunctioning.
