 ====== Amiga 1200/AGA ======
-The Amiga 1200 (a.k.a. Amiga AGA) is a personal computer developed by Commodore. It was released in 1992.
+The Amiga 1200 (a.k.a. Amiga AGA, a.k.a. Amiga home computer) is a line of personal computers developed by Commodore. The first Advanced Graphics Architecture (AGA), the Amiga 4000, was released in 1992.
+The AGA line is the last upgraded form of the Amiga home computer line, succeeding [[systems:amiga500|the Amiga 8-bit computers]]. It includes the following models:
+  * Amiga 4000 (Motorola 68EC030/68040)
+  * Amiga 1200 (Motorola 68EC020)
+  * Amiga 4000T (Motorola 68040/68060)
+The AGA graphic chipset could display up to 256 colors, boosting up to 262 thousand colors (selectable from a 16 million color palette) in HAM-8 mode.
+The Amiga 1200 is the most well-known (probably because the Amiga 4000 was prohibitively expensive). It would be Commodore's last low-budget model before filing for bankruptcy in 1994.
-It is an upgraded form of the [[systems:amiga500|Amiga 500]], and the software/games for both systems //usually// had versions for both computers. It features a Motorola 68EC020 CPU.
+The AGA line was different enough from the 8-bit computers that software/games were //usually// developed specific to both versions. If available, the AGA version (1200 commonly) is the superior version.
 This system scrapes metadata for the "amiga" group(s) and loads the ''amiga1200'' set from the currently selected theme, if available.

 ===== BIOS =====
-No Amiga 1200 emulator in Batocera needs a BIOS file to run.
+If only interested in emulating the Amiga 1200, only ''bios/amiga/kick40068.A1200'' is needed. The rest are for if desiring to emulate a specific model or needing to work around an in-game bug which only affects certain OS versions.

-[[https://docs.libretro.com/|RetroArch]] (formerly SSNES), is a ubiquitous frontend that can run multiple "cores", which are essentially the emulators themselves. The most common cores use the [[https://www.libretro.com/|libretro]] API, so that's why cores run in RetroArch in Batocera are referred to as "libretro: (core name)". RetroArch aims to unify the feature set of all libretro cores and offer a universal, familiar interface independent of platform.
