# Game Boy Advance
|
||
|
|
|
||
|
|
a portable video game console from Nintendo, succeeding the Game Boy.
|
||
|
|
|
||
|
|
it adds two stereo sample audio channels which can be used directly ("DMA", left/right) or used in a software mixing driver (most games do this) in order to have multiple voices.

## Game Boy Advance (MinMod)
|
||
|
|
|
||
|
|
this is the software mixing driver available in Furnace. it is written by Natt Akuma.
|
||
|
|
it features echo and up to 16 voices.
|
||
|
|
|
||
|
|
- `10xx`: **change wave.**
|
||
|
|
- `11xy`: **configure echo.**
|
||
|
|
- this effect is kinda odd. this is how it works:
|
||
|
|
|

|
|
> How do you echo on GBA
|
||
|
|
>
|
||
|
|
> Create an empty instrment and put a very high note of it in channel 1 then do 110x in effect column and set volume column to set feedback and do nothing else on it
|
||
|
|
|
||
|
|
- `12xy`: **toggle invert.**
|
||
|
|
- `x` left channel.
|
||
|
|
- `y` right channel.
