      I'm having some serious trouble trying to get the pi4 and retropie Dreamcast emulators to run full speed like others have reported I've overclocked the arm to 2100 and the GPU to 750 confirmed that the clock speed has increased but it's not translating into better performance in retropie
      Any help greatly appreciated

        @evileyecheese more information about your setup would be also greatly appreciated as mentioned here: https://retropie.org.uk/forum/topic/3/read-this-first

        In general: DC (as well as most NAOMI/AtomisWave-) games run great on PI4, even without overclocking.

          @sirhenrythe5th sorry, I'm a total noob at this, I'm running a pi4b with 2 gig of ram I've edited config.txt via notepad ++ upped the voltage to 6 and confirmed the clock speed has increased.

            @evileyecheese to help you seriously we still need some more information, that you are using a Pi is clear, the ammount of ram is not important at all.
            More important are things like: which emulator, which versin of retropie, what kind of modifications,....
            Did you open the link i posted you?
            There you would have seen the following inportant questions:

            Pi Model or other hardware: (B, B+, 2 B, 3, X86 PC etc..)
            Power Supply used: (If using a Pi)
            RetroPie Version Used (eg 3.6, 3.8.1, 4.1 - do not write latest):
            Built From: (Pre made SD Image on RetroPie website, Berryboot, or on top of existing OS etc.. - please provide the filename of any image used)
            USB Devices connected:
            Controller used:
            Error messages received:
            Verbose log (if relevant):
            Guide used: (Mention if you followed a guide)
            File: (File with issue - with FULL path)
            Emulator: (Name of emulator - if applicable)
            Attachment of config files: (PLEASE USE PASTEBIN.COM FOR LARGE LOGS)
            How to replicate the problem:

                @evileyecheese anyone telling you that dreamcast will run fullspeed on pi4 in all scenarios after an overclock, is not in full possession of the facts. overclocking may provide a small benefit in certain scenarios, but nothing major, and it won't help if there's a fundamental config issue happening, which we could diagnose with a verbose log etc.

                  its mainly marvel vs capcom 2 which seems to be a demanding title also ikaruga on naomi
                  i was using redream but got slightly better results in flycast in terms of speed and the snk fighting games on atomiswave are increadibly choppy
                  im running version 4.7.1 official download
                  i have literally no idea what im doing
                  im using official psu

                  config.txt as follows

                  For more options and information see

                  http://rpf.io/configtxt

                  Some settings may impact device functionality. See link above for details

                  uncomment if you get no picture on HDMI for a default "safe" mode

                  #hdmi_safe=1

                  uncomment this if your display has a black border of unused pixels visible

                  and your display can output without overscan

                  disable_overscan=1

                  uncomment the following to adjust overscan. Use positive numbers if console

                  goes off screen, and negative if there is too much border

                  #overscan_left=16
                  #overscan_right=16
                  #overscan_top=16
                  #overscan_bottom=16

                  uncomment to force a console size. By default it will be display's size minus

                  overscan.

                  #framebuffer_width=1280
                  #framebuffer_height=720

                  uncomment if hdmi display is not detected and composite is being output

                  hdmi_force_hotplug=1

                  uncomment to force a specific HDMI mode (this will force VGA)

                  hdmi_group=2
                  hdmi_mode=85

                  uncomment to force a HDMI mode rather than DVI. This can make audio work in

                  DMT (computer monitor) modes

                  hdmi_drive=2

                  uncomment to increase signal to HDMI, if you have interference, blanking, or

                  no display

                  #config_hdmi_boost=4

                  uncomment for composite PAL

                  #sdtv_mode=2

                  uncomment to overclock the arm. 700 MHz is the default.

                  #arm_freq=800

                  Uncomment some or all of these to enable the optional hardware interfaces

                  #dtparam=i2c_arm=on
                  #dtparam=i2s=on
                  #dtparam=spi=on

                  Uncomment this to enable infrared communication.

                  #dtoverlay=gpio-ir,gpio_pin=17
                  #dtoverlay=gpio-ir-tx,gpio_pin=18

                  Additional overlays and parameters are documented /boot/overlays/README

                  Enable audio (loads snd_bcm2835)

                  dtparam=audio=on

                  [pi4]

                  Enable DRM VC4 V3D driver on top of the dispmanx display stack

                  dtoverlay=vc4-fkms-v3d
                  max_framebuffers=2

                  [all]
                  dtoverlay=vc4-fkms-v3d
                  #overscan_scale=1

                  #Add these 2 lines for CPU Overclock
                  over_voltage=6
                  arm_freq=2100

                        @evileyecheese the log is in incomplete. you should show the whole file, and also the override it refers to:
