+# 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.
+
+# effects
+
+- `10xx`: **change wave.**
+
+## 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.
+
+## info
+
+this chip uses the [GBA DMA](../4-instrument/gbadma.md) and [GBA MinMod](../4-instrument/gbaminmod.md) instrument editors.
