lr-reicast fails to launch (x86/x64)

johnodon

Maybe this is the same issue others saw with Retroarch and 18.04? I'll try a different video driver (right now it is gl)

johnodon

Well, this fixed the crash:

https://retropie.org.uk/forum/post/152319 ( have Intel HD graphics so it is at the bottom of that post).

Setting DRI = 2 or 3 have a seriously negative impact on performance, even in the ES gui.

@johnodon No, it's not because of the renderer, it's a core issue - something similar to https://github.com/libretro/reicast-emulator/issues/199.

johnodon

Is this really just my bad timing to test that core? :)

mitu

@johnodon Maybe, it can also be the build options in the script are not covering all the bases. Just to rule out the build options, you could try installing RetroArch and the core directly and see if it works (using a recent build of RA and the core).

I'll do that. Stay tuned.

Thanks @barbudreadmon. I saw your answer in the other thread and will manually create the /dc/data folder in the rom path. However, I think @mitu is right and this is a core issue.

I re-installed 18.04 and pulled RA/cores from the testing/nightly PPA which gave me a different version of the lr-reicast core (0.1-r201808021716-31c1caf-7~ubuntu18.04.1) and all worked as expected.

If I compile from git (lr-reicast commit 4a44ef4), I get the crashes. Diegoviola, who opened the original issue for when compiling shaders, has opened a second issue:
https://github.com/libretro/reicast-emulator/issues/203

@mitu thinks this may be the culprit.

I said what you're experiencing might be a similar issue, not the same (since the issue I mentioned was already solved). The issue you posted though seems like the one you're experiencing.
If the PPA works, then there might be a problem with the build options in the RetroPie-Setup script. The setup script will pull the latest version from github, so maybe the PPA was created from a previous commit. You can open the RGUI and the core version should be at the bottom, so you can compare both versions.

EDIT: rephrasing.

Then you misread my answer, the issue lies in your config, and that's 100% sure from the output you posted. While creating this folder could work, this is not the root issue. Anyway i'm 100% sure your issue is unrelated to rendering stuff, as explained your system directory is not properly handled by your configuration (because of one of the 2 parameters i mentioned), so :

it won't locate your bios
it will try to create a folder it shouldn't and can't.

johnodon

UPDATE: @barbudreadmon I deleted the data folder at /home/pi/Retropie/BIOS/dc and the script was able to create it at that location without error so this indeed looks like that was a configuration issue.

@barbudreadmon as far as the path issue, I performed a fresh RP install on a new a clean build of Ubuntu Server x64 18.04.1 and manually created the paths. The path errors have disappeared. These are the only things I did...

I manually created /home/pi/Retropie/roms/dreamcast/dc/data/. The 'dc' folder has the relevant bios files.
I also copied the bios files to /home/pi/Retropie/BIOS/dc/
As far as RP install, the ONLY things I did that are 'non-standard' are:
- Install the lr-reicast core
I did not make any other configuration changes

I launched the game with verbose logging.

pi@ubuntu:/dev/shm$ cat runcommand.info

runcommand.log is here: https://pastebin.com/xt2CCzP4

Line 213 is where we start to see the compile failures:

@mitu I listed the core versions I was getting with nightly PPA vs GIT here (31c1caf vs. 4a44ef4 respectively): https://retropie.org.uk/forum/post/157385

This was verified by looking at the core version in RA itself. FYI...this last install put me at commit bbcc720c with the same result.

Again, that's not something you have to do if the 2 parameters i mentioned (system_directory and systemfiles_in_content_dir) have the proper values.

It seems you indeed have a renderer issue besides the path issue, those happen a lot depending on hardware/commit, try opening an issue on github, and don't forget to mention your hardware.

Sounds good. I just wanted to confirm that this wasn't a retropie script issue before I go posting an issue on the libretro github.

Thanks for the help guys!

we had one problem with the script and docs which I have fixed in that it said to put the BIOS in the ~/RetroPie/BIOS folder instead of the ~/RetroPie/BIOS/dc folder. I assume the location must have changed at some point. However this issue shouldn't have caused your problem and it's working fine on my system.

@BuZz What version of the lr-reicast core are you using? The thought is that it may have been broken in a recent commit (at least maybe for some specific HW).

BuZz

@johnodon I built it from source an hour ago. Not in front of pc so can't say what version.

johnodon

Updated the core this morning and I am now able to launch games.

Great, thanks for testing this !
