      @dankcushions Then why am I seeing such noticeable differences upon changing options? and the documentation I read showed mupen64-gfxplugin-accuracy = "high" was directly tied to Glide exclusively.

      it is. both standalone and lr can use the GLideN64 plugin, but they're controlled by different config files:

      • the mupen64plus-GLideN64 (standalone) version of mupen64plus has its GLideN64 settings in opt/retropie/configs/n64/mupen64plus.cfg
      • the lr- version has it's GLideN64 settings in the retroarch-core-config.cfg file you are editing.

      you must be mistaken about what you're running via the runcommand as there's no way that the standalone (ie, none-lr) version cares about what is in retroarch-core-options.cfg. it doesn't read that file and wouldn't understand it if it could :)

        Sorry edited a comment instead of replying haven't slept.

        So Are the same variables from here http://wiki.libretro.com/index.php?title=Mupen64Plus then able to be changed and modified in the opt/retropie/configs/n64/mupen64plus.cfg file and then properly applied?

          @Twitch0815 those options are only for the the libretro (lr-) verison of the core, not the standalone. the standalone should have equivalent options but none of them will have the exact same name in mupen64plus.cfg. they'll be something different.

          mupen64plus.cfg is auto-populated with all the default options when you run a game on standalone so you can just tweak what's already there.

            Great post I had already tried overclocking mine but this just gives me a few more things to modify thanks!

              Great post, the play looks great. I will be trying the N64 emulator again with these new tweaks. Have you tried Castlevania? The last time I played around with it the opening screen had some "tiling" problems and the transparent overlay to choose your character was black. Game play had some lag.

              Just to verify the options settings above are for the lr version and not the standalone?

                  Hello,

                  I have test your configuration today.
                  It's look good for a lot of rom, but I always have a realy bad sound with Wave Race.

                  Have you do something for this? Or it's just on my Pi?

                  I'm using a raspberry PI 3, with retropie 3.6 (install with a SD-card image)

                  If someone has an idea... :)

                    Did you try the 4 diff emulator plugins via run command
                    I remember trying ti once did not seem bad at all I can mess around with a bit i am working with hi res texture packs right now releasing another video shortly.

                    The hardware overclocks are for any raspi 3

                    The tweaks above in the file apply to libretro version but for the life of me even though it sould seem ti improve performance on mupen64plus
                    So if you see that same thing let me know something that I am trying to determine if it is a placebo effect or not.

                    Ill update everyone as I finish my tweaking.

                      The hardware overclock would not work on a pi2.
                      If you check https://github.com/retropie/retropie-setup/wiki/Overclocking the first top half details settings and steps to modify your pi 2

                      But if you want results like in the video you are going to need a pi 3.

                      Overclocking a 2 can get some games to work but not as well or as many as the pi 3.

                        Have you tried hitting x and switching to a few different plugins?

                        What overclock settings are you using?

                          Hello,

                          Yes I have try different plugins. It's a little better with Gles2 but not as good as your video ^^.

                          I use the same overclocking setting as you. I will testing other setting today and I will see if I can get a good results :)

                            Where did you get your case? I see you have some standoffs on the bottom plate so you have enough room to add a heatsink. The bottom is the memory chip and the top of the Pi is the GPU?

                              http://www.amazon.com/gp/product/B00SH6DBY6/ref=s9_simh_gw_g147_i1_r?ie=UTF8&fpl=fresh&pf_rd_m=ATVPDKIKX0DER&pf_rd_s=desktop-1&pf_rd_r=1ZWVYP5R6KTSE6GTE017&pf_rd_t=36701&pf_rd_p=2437869742&pf_rd_i=desktop

                              Just search around on amazon

                              The 2 chips on the top are the CPU the bigger one and the USB/Nic Controlling chip
                              Bottom chip is the shared memory GPU
                              As I understand.

                                Thanks Twitch, I appreciate the link. I like the looks of that "case". I will get one ordered today. Looking forward to your next video.

                                  Hello,

                                  Wave race sound still working bad for me.
                                  Maybe a connectivity problem or just my old TV...

                                  In another style, I test 1080° and it's great.
                                  Just a little overclock setting :
                                  arm_freq=1300
                                  over_voltage=6
                                  temp_limit=80
                                  core_freq=500

                                  and use Glide.
                                  I don't see this game on your video, you can have a lot of fun with it :)

                                    Try adding these two
                                    gpu_mem=450
                                    v3d_freq=500
                                    and make sure wave rice is using glide and resolution

                                    you can see how it is running on my setup in this video


                                    Starting around the 1 minute mark
                                    Both stock and with the high res texture package enabled

                                        thanks for that. I got also a Pi3 but nt configured right now. I want just to solve the MarioKart 64 Sound issue on the pi2. everytime when the sound scrap the game is also a little bit stocking...and that sucks
