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

shavecat

Hey, lr-flycast
i just not loading give my back to the emulationstaion .
or its going really slowww and i got retrorch there.
weird ?

im getting also this on runcommand.log

dankcushions

your log is for reicast, not lr-flycast.

@shavecat Please don't use images with showing log files, it's hard to look and search for errors. Use pastebin.com for large logs and for a few lines, just surround them with code blocks.

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

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.
