lr-flycast dreamcast after loading the dreamcast logo and sega logo go to black screen need help ... (scroll all the way down plz)

shavecat

for the reicast games like jet set radio or sonic after select the 60mhz
it goes out , this is the image of the runcommand.
and for the lr-flycast runcommand-

What does this mean ?

really slowwwwwwww

That could be for a number of reasons - what system are you running on ? Is every game slow or just some of them ?

shavecat

@mitu
pi3b+ 4.5 .
just now update .
before the dreamcast was running with no problems with the recast .
and its quit with some games after picking the MHZ.

and the lr-flycast , everything is really slow... everygame.
any ideas ?
or just go back to my 4.4 image save ? (will be shame )

I was referring to the hardware setup you have - as asked in https://retropie.org.uk/forum/topic/3/read-this-first. Do you have any overclock ? Is your Temperature ok ? Do you get any over-voltage signs ? What's you GPU memory split ?

and its quit with some games after picking the MHZ.

Where exactly are you picking the MHZ ? Is this the resolution change in the Runcommand launch menu ?

then it takes to load the game like 1 min' from then everything really slow....

Is it for every game like this ? No matter the size ?

shavecat

@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

After the logo of a game
TV settings
50MHZ / 60MHZ / TEST
after i pick 50/60
its quit .

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.

shavecat

@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.

barbudreadmon

@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

barbudreadmon

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

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

so why it so slow ?

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.

quicksilver

@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.

shavecat

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
