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

Options

--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.
0: VSync (most compatible)
1: 1000Hz (default)
2: 500Hz
3: 350Hz
4: 300Hz
5: 250Hz
6: 200Hz
7: 150Hz
8: 150Hz
9: 125Hz
10: 125Hz
11: 100Hz
--cursor=<path>, --no-cursor
Load texture palette for cursors (default: point.tpl.gz).
--overlay=<path>, --no-overlay
Load texture palette for graphic overlays (default: frame.tpl.gz).
--overlay-id=<ID>
Set texture palette index for graphic overlay. The default is the Game Boy Player Start-up Disc's Frame setting (0 to 19).
--overlay-scale=<x:y>
Set texture scale for graphic overlay (default: auto).
--filter=<[none|blend|deflicker|accumulate|scale2x[ex|plus]|eagle2x|scan2x|normal2x][,prescale|no-prescale]>
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). Setting this option to none is not recommended when using linear RGB rendering.
Applied during prescaling.
--scaler=<nearest|bilinear|area|box>
Set image scaling filter (default: area). Setting this option to nearest is not recommended when using fractional scaling or a non-square pixel aspect ratio.
--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.
