Issue loading reicast core

Brakechute · 7 April 2019 17:36

Hello all… not sure if this is a Lakka issue, a RetroArch issue or a user (me) issue, so I thought if I left it here someone would tell me if it belongs somewhere else.

I had upgraded from v2.2 to 2.2.1 to 2.2.2 and things were getting a little glitchy so I wiped the drive and installed v2.2.2 fresh, reloaded BIOSs & ROMs, etc. Now I cannot get the reicast core to load in Lakka 2.2.2 (x86_64). I am sure it did before on the older version running on the same hardware, but now it apparently can’t load some file and I don’t know why. I have attempted it with the packaged core as well as the most recent one I could locate (20.Mar.2019) in /Storage/Cores with the same results. Any insight would be appreciated.

Additional info: The latest “nightly” had the same issue, however the ver 2.2.1 image does not, as in reicast core loads/runs fine. Didn’t know if that would help track it down.

Sivarticus · 1 April 2019 19:27

I was having the same problem. I was able to extract the Reicast core from the 2.2.1 build and save it to the Cores folder and it runs perfect. I changed the directory from /tmp/cores to /storage/cores and moved all the cores i normally use there to save the hassle of changing the directory every time.

Sampler · 2 April 2019 15:54

Can you post the core? Thank you!

Sivarticus · 2 April 2019 17:53

Sure thing. I’ll do it when I get home from work tonight.

Thanks !! Going to try the core.

BDJoe360 · 3 April 2019 18:49

Thank you for your core document！ Can you share how to extract the Reicast core from the 2.2.1 build?

Sivarticus · 3 April 2019 20:55

Of course. So first you’ll need 7zip. Right click on the Lakka img file and hover over the 7zip menu and click “Open Archive”. Navigate to \system.img\SYSTEM\usr\lib\libretro. All core files are stored here. Extract any “.so” file you need by just drag and dropping to your desired location.

Now keep in mind, when saving cores to the “Cores” folder in Lakka Storage, you’ll need to change the directory Lakka points to within the settings. Otherwise you’ll keep getting “failed to load libretro core” when launching games, because it’s looking for the associated core in the default /tmp/cores/ directory.

Let me know if you need help with anything else.

BDJoe360 · 4 April 2019 03:25

Got it! Thankyou very much!!!

jabedoben · 7 April 2019 20:43

This worked for me as well. Thanks for providing the core!

Sivarticus · 23 June 2019 21:24

So the workaround I was previously using no longer works. I’m currently using the 6/16 Lakka nightly and the now renamed Flycast core won’t load. Per the logs, it’s the same “libgomp.so.1: cannot open shared object file: No such file or directory” error that was occurring before. Does anyone know how to fix that?

flyinghead · 24 June 2019 06:35

I thought the core was statically linked so that there is no dll dependency but I guess I was wrong or the build has a problem.

Anyway you should be able to find the missing dlls in any Windows build on this page: https://flyinghead.github.io/flycast-builds/

Sivarticus · 24 June 2019 20:52

Thanks! I’ll check this out when I get home from work tonight and let you know if this worked.

Update: Ok, so I have the dll, but no idea where to put it.

Sivarticus · 24 June 2019 21:14

Ok, tried a few things to get Flycast running:

Pulled the Flycast core out of the 6/16 Lakka image and saved it to the /storage/cores folder to try later.
Placed the libgomp dll in the same folder as the other cores I have saved in the /storage/cores folder. Failed launch.
Captured the error log which was now showing that there was a MIDI initialization error. Changed MIDI driver to null and relaunched. Nothing.
Deleted libgomp dll and tried again. Nothing.
Changed video driver from glcore to gl, did not replace libgomp dll. Worked.
Tried launching Flycast from /tmp/cores, got the libgomp error again.

Not really sure what’s happening. shrug

some issue here. since i updated to lakka 2.2.2 reicast is not loading anymore. gpu is Intel HD 530. i wonder we can get updated reicast cores whithout that issue.
