lr-genesis-plus-gx on RPI4: crashes

lekzerum

hello,
i used lr-genesis-plus-gx on RPI3b+ before for 4-player-games.
But on RPI4 it constantly crashes with most games i tried (super skidmarks for example). I tried 4.6 + 4.7.1.
Picodrive is stable - but since it does not support 4-player games this does not help me.
Any ideas ?

Hello and welcome to this forum.

We need more information about your system. Please provide all the information that's asked for in https://retropie.org.uk/forum/topic/3/read-this-first.

In addition to that, a verbose log of lr-genesis-plus-gx could be helpful. See https://retropie.org.uk/docs/Runcommand/#launch-with-verbose-logging.

@clyde i tried more games in the meanwhlie. Hardly any game works.
They all crash with that (verboselog-line:)
/opt/retropie/supplementary/runcommand/runcommand.sh: line 1283: 7046 Bus error
(that 7046 differs)

even simple games crash. My last try was flappy bird - a homebrew game.
further down i paste the verbose log

Alas, I don't have any experience with this error. Have you updated RetroPie recently? If not, I would try that first to negate any problems that may be already be fixed in the current code.

lekzerum

@clyde yes, i also tried "from source" today

Clyde

@lekzerum Do you have the Mega Drive / Genesis bios installed?

https://retropie.org.uk/docs/Mega-Drive-Genesis/#bios

lekzerum

@clyde i just discovered something funny: i took the "genesis_plus_gx_libretro.so" from my older RPI3-32bit retropie 4.5 -> copied it to my rpi4 => it works!!!

Clyde

@lekzerum Strange, but if it works …

Maybe someone with more internal knowledge stumbles upon this thread and can shed some light on it.

In the meanwhile, have fun with your 4P games. 👍

hooperre

I'm having a similar issue with Sega CD / lr-genesis-plus-gx on the pi4. My files are .chd format. Worked in my previous build, verified the BIOS against the official documentation... nothing.

@lekzerum Any chance you could throw that file in a google drive link for me to try?
