I am running RetroPie 4.4.4, have about 4 or 5 systems running, and that's about all.
UPDATE: Found the issue. The god-forsaken BIOS file was a .md file, I've got it solved.

@Kalamabrew su is not sudo, they're different programs. I understood you're not able to use sudo - you'll have to investigate more on how to enable sudo for your user and then re-do the installation.

Thanks Clyde, I'll keep that solution in mind. I know knockoff PS3 controllers are tricky. Thanks for your help :)

@romanCitizen that's way out of date. Use the current docs.

@brimby said in pcsx-rearmed plays fine but lr-pcsx-rearmed has major sound distortion and slowdown:

@barbudreadmon By "read ahead", did you mean fast-forward?

No, read ahead is the thing to reduce input latency

@mitu Sweet, that makes sense. Thanks.

This is fixed now if you update retropie-setup.

@cookiepanda Can you get the ~/.emulationstation/es_log.txt file and upload it to pastebin.com to take a look ? Has the installation been performed successfully or there were errors during installation ?

Replying to this old topic with the solution that worked for me, after finding this question via google with no reply.

It's likely your left/right triggers were configured incorrectly. If they're configured for minus axis, retroarch believes they are held down when the game launches and everything acts weird. It's likely the retroarch menus are un-navigable as well.

To fix the problem, go to "configure input" again and make sure left trigger is "Axis 5+" and right trigger is "Axis 4+". If they're negative the emulator thinks they're held down and that's causing the problems.

Hope this helps anyone else coming across this problem via google.

@WalkerMan2 don't post to old topics.

@xFlesk said in Amiberry. how to disable those awful scanlines ?:

i dont know what happend with this amazing emulator, but since some update it plays games with those disgusting scanlines which are completly gamebreaking for me. is there any way to turn this shitty scanlines off ? i cant see any option related to it in F12 menu.
thank you in advance

Assuming we're talking about the same visual affect, turning off Line Doubling in the Display section removed those scanlines for me.

@Hyperlord You're supposed to run skyscraper with an online scraping source to get any data. Your command line doesn't show that. So you should run it like

Syscraper -p nes -s screenscraper --videos

If you don't specify a scraping source (-s), then it will query the LocalDB, which might not have any videos scraped.

@dankcushions Ah, okay! I didn't know that, thanks.

@mitu Just stumbled over this thread because I am a proud owner of two Aimtrak lightguns since last saturday, and I'm searching for any information about their setup. :)

Following the links from the video's description, I found the github page of the script in question:

https://github.com/Shakz76/Eazy-Hax-RetroPie-Toolkit/

It seems like it modifies an existing Retropie installation and adds some functionality the author deemed to be useful. I didn't dive deeper into it, because I prefer to use Retropie's own tools as long as they get the job done as well.

Getting my Aimtraks to work with any kind of MAME is my next goal, but at present I can't help much further.
