@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.

@barbudreadmon
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.

shavecat

Got it fix the 50MHZ 60MHZ
only the lr-flycast dont work right.

@shavecat said in lr-flycast dreamcast not working and some dreamcast games quit after pick TV SETTINGS 60mhz(after logo game):

have it -

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

shavecat

@barbudreadmon
what to add exactly ?
thanks !

quicksilver

@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.

shavecat

@quicksilver
thanks !
so why it so slow ?
on the recast its working fine

quicksilver

@shavecat I have no clue

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.

so nothing i can do to make it faster ? :'(

Did you set the core options as i told you ?

shavecat

@barbudreadmon
yes its okay .
still slow
if its loading ... takes a will to load even

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.
