lr-reicast -
just going back to the emulation station after i pick a rom.
any idea why ?

Yes, see post by BJRetro (some posts above)

basically you have to edit /opt/retropie/configs/dreamcast/emulators.cfg and add
< /dev/null
at the very end of the line inside the last quotation mark in the line that says lr-reicast=

@shavecat
in /config/dreamcast/emulators.cfg edit and add < /dev/null at the end.
lr-reicast = "/opt/retropie/emulators/retroarch/bin/retroarch -L /opt/retropie/libretrocores/lr-reicast/reicast_libretro.so --config /opt/retropie/configs/dreamcast/retroarch.cfg %ROM% </dev/null"

@ninuzzu ~~Looks like that fix was for GLES 3 devices. Pi is GlES 2 so that fix is not likely to work.~~

@quicksilver nope, this fix also works on raspberry, i had to do it on mine, however it seems it wasn't needed with earlier version of retroarch (i didn't have the issue with my previous RA from mid-december)

@shavecat did you follow all instructions, including bioses ?

@ninuzzu i destroyed my sd card last week so i can't send you a copy of my core

ninuzzu

@barbudreadmon Metal Slug 6 and Wacky Races (lr-reicast) run much better with your oveclock settings. Crazy taxi is now running almost perfect ^^
Thanks

@ninuzzu On a pi3b+ the bottleneck for dreamcast/N64 is the GPU. Specifically getting the core_freq as high as possible (and be stable!) will give you the best possible results (on your pi).

There was some recent discussion in regards to overclocking and stability testing here that may be helpful:

If it just stopped working without any action from you, then you have a corrupt file somewhere, or maybe worse (corrupted sd).

did you put all the bios in the folder /bios/dc/ ?

shavecat

yes the bios files in the folder.
and no didnt touch the and dont have something wrong with my sd card , everything else work's fine even dreamcast with the lr - emulator .

barbudreadmon

@shavecat Well, programs don't just "stop working" without a reason, and the reasons can only be :

change of settings
corrupt file
corrupt hardware

Sorry but i won't be able to help you if you are telling me none of those happened.

So is anyone nice enough to upload their reicast binary, pre-update, from around retropie 4.4?

@Efriim https://retropie.org.uk/forum/topic/17378/what-is-your-favorite-shoot-em-up/144

There is a copy here

shavecat

@barbudreadmon
really nothing that is the problem ,
even try to uninstall it and install from the stat.

pjft

@shavecat what's the log in /dev/shm/runcommand.log when you run it?

shavecat

@pjft
lr-reicast

tried also to make a folder in the usb roms/dreamcast/dc/data , and its just give me black screnn and stck on it.
but with the reicast omx works fine

Efriim

@pjft @quicksilver
Thanks for the binary, that is exactly what I was asking for.

Efriim

Is there an idea of a script for when your ps3 controller timesout in the middle of a dreamcast game and when you resync it to the pi, the control doesn't go back through to the emulator; to resync with reicast or anything?

barbudreadmon

@shavecat A lot of issues here, again, if it worked previously, it's impossible it came to this without any action from you

First issue :

creating dir: /media/usb0/roms/dreamcast//dc/data
mkdir(/media/usb0/roms/dreamcast//dc/data) error: No such file or directory

The actual path it's trying to create is system_directory/dc/data, where system_directory is your RA bios folder, since it thinks your bios folder is your rom folder, it means system_directory is not defined in your retroarch.cfg, which is pretty bad because it'll also search for your bioses in /media/usb0/roms/dreamcast/dc/

Second issue :

find blahblahblah: No such file or directory
again
again

It's failing on spaces in names, so something isn't set right in your retropie setup and i've no idea what it is. Are you sure you copied the hack in /opt/retropie/configs/dreamcast/emulators.cfg properly ? A quick fix would be to remove all spaces from the name of your dreamcast isos.
