!Breaking change! Changed the config file format to use strings in many places instead of values.
Added a new saturation setting for color profiles other than none. Removed lcdGamma and displayGamma temporarily. Updated README.md with all the changes.

### Video
|
||||
Video-related settings.
|
||||
|
||||
`u8 scaler` - Video scaler. 0 = none, 1 = bilinear, 2 = hardware.
|
||||
* Default: `2`
|
||||
`string scaler` - Video scaler.
|
||||
* Default: `matrix`
|
||||
* Options: `none`, `bilinear`, `matrix`
|
||||
|
||||
`float gbaGamma` - GBA input gamma
|
||||
* Default: `2.2`
|
||||
`string colorProfile` - Color correction profile.
|
||||
* Default: `none`
|
||||
* Options: `none`, `gba`, `nds`, `nds_white`, `nso`, `identity`
|
||||
* If you just want less saturated colors or change other basic settings like contrast or brightness then set this to `identity`.
|
||||
* Due to most 2/3DS LCDs not being calibrated correctly from factory the look may not match exactly what you see on real hardware.
|
||||
* Due to a lot of extra RAM access and extra CPU processing per frame, battery runtime is affected with color profiles other than `none`.
|
||||
|
||||
`float lcdGamma` - Output LCD gamma
|
||||
* Default : `1.54`
|
||||
|
||||
`float contrast` - Screen gain
|
||||
`float contrast` - Screen gain. No effect when `colorProfile=none`.
|

||||
`string colorProfile` - Color correction profile. `none`, `gba`, `nds` or `nds_white`.
|
||||
* Default: `none`
|
||||
* For the gba profile it's recommended to adjust lcdGamma to match a GBA. For New 3DS XL with IPS LCD roughly 1.8 is good.
|
||||
* Due to most 2/3DS LCDs not being calibrated correctly from factory the look may not match exactly what you see on a real GBA.
|
||||
* Due to a lot of extra RAM access and up to 6.3 ms (worst case for scaler=2) of extra CPU processing time per frame, battery run time is affected with color profiles other than none.
|
||||
`float saturation` - Screen saturation. No effect when `colorProfile=none`.
|
||||
* Default: `1.0`
|
||||

||||
### Audio
|
||||

|
||||
|
||||
`u8 audioOut` - Audio output. 0 = auto, 1 = speakers, 2 = headphones.

|
||||
* Default: `auto`
|
||||
* Options: `auto`, `speakers`, `headphones`
|
||||
|
||||
`s8 volume` - Audio volume. Values above 48 mean control via volume slider. Range -128 (muted) to -20 (100%). Avoid the range -19 to 48.

## Patches
|
||||
open_agb_firm supports automatically applying IPS and UPS patches. To use a patch, rename the patch file to match the ROM file name (without the extension).
