+Libretro fork of bsnes. As close to upstream as possible.
+
+bsnes is a Super Nintendo emulator that began development on 2004-10-14. It
+focuses on accuracy and clean code above all else. It never uses speed or
+compatibilty hacks. As a result, the minimum system requirements are greater
+than with other emulators. bsnes comes in three different profiles (accuracy,
+balance and performance) which contain minor differences in the PPU (graphics)
+emulation.
+
+bsnes requires the following BIOS image files under the system directory for
+operation:
+
+* dsp1.data.rom (DSP1 DATA) (CRC: c8347cbd)
+* dsp1.program.rom (DSP1 PROGRAM) (CRC: db9a4c92)
+* dsp1b.data.rom (DSP1B DATA) (CRC: 37a252c6)
+* dsp1b.program.rom (DSP1B PROGRAM)) (CRC: 66a73998)
+* dsp2.data.rom (DSP2 DATA) (CRC: b3893c70)
+* dsp2.program.rom (DSP2 PROGRAM) (CRC: 0c1cf838)
+* dsp3.data.rom (DSP3 DATA) (CRC: 8b41a2bd)
+* dsp3.program.rom (DSP3 PROGRAM) (CRC: f29be51c)
+* dsp4.data.rom (DSP4 DATA) (CRC: efa8b9b2)
+* dsp4.program.rom (DSP4 PROGRAM) (CRC: 14b77ae3)
+* cx4.data.rom (Cx4 DATA) (CRC: b6e76a6a)
+* st010.data.rom (ST-0010 DATA) (CRC: 216081b2)
+* st010.program.rom (ST-0010 PROGRAM) (CRC: 691cbb4f)
+* st011.data.rom (ST-0011 DATA) (CRC: 803256a7)
+* st011.program.rom (ST-0011 PROGRAM) (CRC: a741e9fb)
+* st018.data.rom (ST-0018 DATA) (CRC: b5255459)
+* st018.program.rom (ST-0018 PROGRAM) (CRC: f73d5e10)
+* sgb.boot.rom (SGB BOOT PROGRAM) (CRC: ec8a83b9 [1])
+
+[1] This is the boot rom only, you need the correct cart image to load SGB
+games.
+
+=====
+
+Super Gameboy is supported via the subsystem API. In RetroArch the API is
+already implemented but only available via CLI. For SGB support you need both
+sgb.boot.rom and the SGB rom. To launch SGB games launch RetroArch like this:
+
+  retroarch -L {path to bsnes core} {path to snes rom} --subsystem sgb {path to gb rom}
+
+Tested snes roms [2]:
+* Super Game Boy (Japan, USA) (Rev 1).sfc (CRC: 27a03c98)[3]
+* Super Game Boy (World) (Rev 2).sfc (CRC: 8a4a174f)
+* Super Game Boy 2 (Japan).sfc (CRC: cb176e45)
+
+[2] Savestates are broken in this implementation.
+[3] Some games don't work with this rom, try version SGB v2 for best results.
+
+=====
+
+By default, this SlackBuild will build the bsnes accuracy core.
+To build the balanced or performance cores, choose any desired cores:
+  CORE="accuracy balanced performance" ./bsnes-libretro.SlackBuild
+
+Or to build all three cores, "all" can be used:
+  CORE="all" ./bsnes-libretro.SlackBuild
