      I have Retropie updated to version 4.6.1 Stretch and trying to install Lr-Bsnes requires me GCC 7.0.
      If I switch to the Buster version, will I solve the problem? I have a Raspberry 3 (normal , not plus) and I don't know if it is compatible.
      I wanted to install this emulator for Super Gameboy support
      Thanks :)

        Installation works on Raspbian Buster, why wouldn't it be compatible ?

        You can get SGB working with lr-mgba, you don't need to install bsnes just for that.

          I don't know, in fact I was asking

          lr-mgba inserts only some overlays, I instead wanted a "complete" emulation of SGB

          thanks

            What's "complete" emulation ?
            I think it does the same thing as MBGA - BSNES uses Sameboy for SGB emulation, doesn't have anything special and I'm not sure the Libretro core includes it.

              SGB had a personal interface accessible by pressing L + R, where it was possible to change the overlay, choose the color set and other small things.
              Unfortunately, to do this, you need an emulator that emulates both GB and SNES

                As stated by mgba author in https://github.com/mgba-emu/mgba/issues/223#issuecomment-183820618, full SGB support is out of the question, it would require implementing a snes emulator in mgba, so the support is only partial.

                So bsnes should be the most complete SGB emulator atm, also fwiw Mesen-S (a new high-accuracy snes emulator from the same author as Mesen, but it doesn't seem to be included on retropie yet) added support for gb/gbc roms last month, with the goal of SGB emulation i guess (i didn't test, i just saw the change in supported extensions).

                  Is bsnes even playable on a pi3? It barely works on a pi4 for non-special chip games. I haven't tried the sgb emulation so I'm not sure if it takes the same amount of processing power.

                    It's the 'new'/latest BSNES, I tested it on a Pi4 with F-Zero and SMW and it was ok (no overclock).
                    Enabling the mode 7 HD option would make it lose a few FPS, maybe overclocking could help with that.

                    For full SGB emulation, I doubt it would work well on a Pi, if it would emulate the full SNES and the SGB on-top, but I didn't try it to see if it works on the LR core.

                      While it's implemented, there might be shenanigans on linux if the warning at https://docs.libretro.com/library/bsnes_performance/#super-gameboy isn't outdated

                        @barbudreadmon Thanks for the pointer. In RetroPie we actually have another BSNES core (there are 5 Libretro repos for BSNES and about 9 cores available in the buildbot !), but the instructions seems to - almost - match. The CLI invocation on that page is wrong (the order of the ROMS is backwards), but it works on Linux with an un-zipped GB ROM.

                        It runs at about 51-53 fps in BSNES on my Pi4 (no overclock) and it looks like you can actually change the palette via L+R as on a SGB.

                          And i guess you aren't even factoring the higan/nside cores :). My understanding of the recent versions of those bsnes cores is that bsnes is for performance, nside is for balanced, and higan is for accuracy; every other flavor of bsnes cores can be ignored i think. That's some nice performance you get with bsnes at stock speed, i never checked the new cores but i remember the old "bsnes performance" core (i guess it's named bsnes2014_performance or something now) being stuck at ~45fps on a 2Ghz x86, well, that was on yoshi's island though.

                            So on my PI3 (not +), it will probably work pretty badly :(
                            I will have to buy a PI4 :D

                              Maybe, but don't expect full speed for the configuration I mentioned.

                                Hi, can you elaborate on exactly which core you are doing this with and what the command line should be to get this to work (I'm fine with the slightly less than 60FPS).

                                  @zerojay The core is lr-bsnes, the command line is explained in https://docs.libretro.com/library/bsnes_performance/#super-gameboy:

                                  retroarch -L {path to bsnes core} {path to GameBoy rom} --subsystem sgb {path to Super GameBoy ROM}

                                    @mitu Thank you. I've got it working and seems to be solid 60FPS for me in everything I've tested with an overclocked Pi 4. I've created my own version of the lr-bsnes scriptmodule that also adds SGB system support: https://raw.githubusercontent.com/zerojay/RetroPie-Extra/master/scriptmodules/libretrocores/lr-bsnes.sh
