      @mitu thanks for the help so -
      Do you have any overclock ?
      yep like before work like charm
      Is your Temperature ok ?
      yep 44 deg'
      Do you get any over-voltage signs ?
      no
      What's you GPU memory split ?
      120 think like before .
      Where exactly are you picking the MHZ ?
      after u pick a game and its start after the logo
      u pick for the tv 50Mhz or 60MHZ
      after u pick it exit
      every game
      Is this the resolution change in the Runcommand launch menu ?
      no
      Is it for every game like this ? No matter the size ?
      yes.

      IM the only one having this problems after update ? with dreamcast only ??
      everything else works perfect. still got my image 4.4 so can always go back but will be shame :\

          @shavecat said in lr-flycast dreamcast not working and some dreamcast games quit after pick 60mhz:

          really slowwwwwwww

          You need to overclock your gpu, 500Mhz is the bare minimum for a good gaming experience, the default 300Mhz is not enough for most games.

            have it -

            arm_freq=1500
core_freq=600
sdram_freq=550
v3d_freq=525
over_voltage=6
sdram_over_voltage=4
temp_limit=70
temp_soft_limit=70

            its only slow on the lr-flycast
            on the recast run fine but getting quit after same games to pick tv settings MHZ.

                No, you don't, gpu_freq is missing from your config.

                    @barbudreadmon he already has core_freq and v3d_freq overclocked in his config.txt. The other blocks of the GPU shouldnt need to be overclocked for emulation purposes.

                          Are you sure v3d_freq is enough ? I always set gpu_freq instead.

                          Maybe your core options then ? lr-flycast's default settings aren't for low-end device, unlike reicast's. iirc, the following settings are especially important :

                          reicast_alpha_sorting = "per-strip (fast, least accurate)"
reicast_div_matching = "auto"
reicast_enable_dsp = "disabled"
reicast_threaded_rendering = "enabled"
reicast_cable_type = "VGA (RGB)"
reicast_frame_skipping = "1"

                          You might need to change frame_skipping on a per-game basis.

                            @barbudreadmon the only other two blocks of the GPU are for the image sensor pipeline (camera) and video decoding. Neither of which are useful here.

                                    I don't get any TV settings to set the MHz, but the game I tried (Jet Grind Radio) loads. What I've noticed is that the dynarec might not be enabled in the config file.

                                    Try editing /opt/retropie/configs/dreamcast/emu.cfg and look for the Dynarec.Enabled line in the [config] section. If it's set to No, then replace it with yes and try running the game again.
