+notes: |
+  TempGBA is a Game Boy Advance emulator forked from gpSP. Originally
+  developed for the Nintendo DS homebrew scene, the libretro port wraps
+  the dynarec-based GBA engine for use in RetroArch.
+
+  The GBA BIOS (gba_bios.bin) is optional. TempGBA includes HLE BIOS
+  stubs inherited from gpSP that handle most SWI calls. The real BIOS
+  improves boot logo display and SWI accuracy for a small number of
+  titles.
+
+  BIOS file goes in the system directory as gba_bios.bin (same path
+  used by gpSP and mGBA).
