Enhanced mGBA (emGBA) is an enhanced port of the Game Boy Advance emulator, based on Game Boy Interface Standard Edition.

--aspect=<w:h>: Specify screen aspect ratio. The default is the Progressive Scan Mode system setting (4:3 or 16:9).
--offset=<x:y>: Set offset. The default is the Screen Position system setting (-32 to +32).
--zoom=<x:y>: Set zoom. The default is the Game Boy Player Start-up Disc's Screen Size setting (2.0 or 2.375).
--rotate=<0-359>: Set rotation (default: 0).
--poll=<0-11>: Set controller polling rate. Use if your third-party controller or controller adapter is malfunctioning.

--cursor=<path>, --no-cursor

Load texture palette (default: point.tpl.gz).

--overlay=<path>, --no-overlay

Load texture palette (default: frame.tpl.gz).

--overlay-id=<ID>

Set texture palette index. The default is the Game Boy Player Start-up Disc's Frame setting (0 to 19).

--overlay-scale=<x:y>

Set texture scale (default: auto).

Set image doubling or screen filter. The default is the Game Boy Player Start-up Disc's Screen Filter setting (none, blend, deflicker).

none: Also known as the Sharp screen filter.
blend[=<red[:green[:blue]]>]: Blend frames n and n-1 (default: 0.55).; Also known as the Soft screen filter.
deflicker[=<red[:green[:blue]]>]: Blend frames n and n-1 where n and n-2 are equal (default: 0.55).; Also known as the Normal screen filter.
accumulate[=<red[:green[:blue]]>]: Blend frames with accumulation buffer (default: 0.55).; As used by the Nintendo 3DS Ambassador games.
scale2x: Apply EPX/Scale2×/AdvMAME2× algorithm.
eagle2x: Apply Eagle algorithm.
prescale, no-prescale: Enable prescaling filter (default: no).

--dither=<none|threshold|bayer8x8|bayer4x4|bayer2x2|cluster8x8|cluster4x4>: Set dithering algorithm (default: threshold).; Applied during prescaling.
--scaler=<nearest|bilinear|area|box>: Set image scaling filter (default: area).
--matrix=<identity|gba|gbi|nds|palm|psp|vba>: Set color matrix (default: gbi).; This translates the RGB color primaries to the standard RGB color space.

identity:	Identity matrix
gba:	Game Boy Advance (by Pokefan531)
gbi:	Game Boy Interface
nds:	Nintendo DS (by Pokefan531)
palm:	Palm Treo 700p (by Pokefan531)
psp:	PlayStation Portable (by Pokefan531)
vba:	VisualBoyAdvance-M (by Pokefan531)

--input-gamma=<red[:green[:blue]]>: Set gamma (default: 2.2).
--output-gamma=<1.0|1.7|2.2>: Specify screen gamma (default: 2.2).
--contrast=<red[:green[:blue]]>: Set gain (default: 1.0).
--brightness=<red[:green[:blue]]>: Set lift (default: 0.0).
--format=<ntsc|pal|pal-m|ntsc-50|pal-60|custom|custom-m|hd60|hd50|hd48|hdcustom>: Set video format. The default is the Video Mode system setting (ntsc, pal-60, pal-m).
--scan-mode=<[interlace|quasi-interlace|non-interlace|non-progressive|progressive][,clock2x|no-clock2x][,size2x|no-size2x]>: Set scan mode. The default is the Progressive Scan Mode system setting (interlace or progressive).

interlace:	15 or 18-22kHz interlaced, deflickering
quasi-interlace:	15 or 18-22kHz segmented frame
non-interlace:	15 or 18-22kHz progressive
non-progressive:	31 or 27-33kHz interlaced, field rendering
progressive:	31 or 27-33kHz progressive

clock2x, no-clock2x: Enable 27MHz pixel clock (default: auto). Enabling doubles the refresh rate for interlace scan modes. Disabling halves the refresh rate for progressive scan modes.; This depend on a compatible video encoder or transmitter not mangling its input.
size2x, no-size2x: Enable 2× video oversampling (default: auto). Enabling halves the refresh rate.; If the video format's horizontal resolution is less or equal to 682, the internal resolution is doubled instead.; This depend on a compatible video encoder or transmitter not mangling its input.

--ipv4-address=<aaa.bbb.ccc.ddd>: Set static IPv4 address.
--ipv4-gateway=<aaa.bbb.ccc.ddd>: Set static IPv4 gateway.
--ipv4-netmask=<aaa.bbb.ccc.ddd>: Set static IPv4 netmask.
--network, --no-network: Enable Broadband Adapter features (default: yes).
<path>: Load ROM.
