@lycros Sadly, I had to put them in all manually. Im sure you figured that out by now.

@Potatopops9 please start a new thread and do not hijack others that are not related to your problem. Thanks.

I can strongly recommend the Crush Pinball series, especially Alien Crush and Devil's Crush (Devil Crash in Japan) for the PC Engine / Turbografx-16. They're often mentioned as maybe the best pinball console games ever made.

Pinball Dreams and Pinball Fantasies are also worth a look. The Amiga versions may be the best because of the music, but the console versions are also quite good as far as I tested them.

I didn't notice any problems running any of them on my non-overclocked Pi 3b non-plus except for the Amiga versions, because I my Pi is only used for arcade and console emulation.

Lowercase, in the BIOS folder.
[EDIT: actually, it was Exec.bin.... for some damn reason the first letter was capitalized and even as I replaced it with other versions all in lowercase, it kept the first letter capitalized. I deleted and replaced it with an all lowercase exec.bin and it works now! Thanks so much!]

@Potatopops9 It's explained in the Docs. However, the scraper does not currently work even if you'll be updating right now - https://retropie.org.uk/forum/topic/20613/

Ok, it looks like everything is working normally now that I put a Ethternet cable in the machine, and it was able to install everything. Looks like I need the Ethernet cable to do stuff.

@mitu

Okay I tried reinstalling "advmame" from the source again as you suggested and now the permissions look like this:

lrwxrwxrwx 1 pi pi 34 Jan 9 08:01 /home/pi/.advance -> /opt/retropie/configs/mame-advmame

First run with "1942.zip" is now working! Thank you!

@mitu I'm hoping it does make it onto Raspberry pi 3b or 4!

OK. Apologies for posting I wasn't aware of this. I'll look for help elsewhere.

Put that in some FAQ at the forum - along with that hdmi issue, or similar issues.

Ok, so it's already mess here, I want ask a question: what is faster - Raspbian installed straight to sd card, or that Pixel (lxde?) desktop installed in RetroPie? I have two sc cards (one with RetroPie and desktop, another one with Raspbian and on top of that RetroPie) and "clear" version of Raspbian is working slower than that desktop port on RetroPie.

Ok so I took a copy and then updated lr-fbalpha and it works with the neogeo.zip in the BIOS directory :)

@BuZz ooops sorry my bad.

@mitu thank you very much

@BuZz Yeah, it is! Alright!

where do the gamelists go?

After a leading a hard but virtuous life, I hope they go to heaven.

@300cpilot Purge would remove the system's config files, not any user configuration files - that's a rule for all packages. Glad you got it fixed.

@cl04ker I also have the same issue in 2019.... I'm trying to rotate my games for use with a vertical monitor... I was told to use : under /opt/retropie/configs/all/ in the configuration editor. The option I changed :

mame2003-tate_mode = "enabled"

While I'm able to change it from disabled to enabled, when I reset my pi it reverts back to disabled, WHY !?

@goobatroopa gles2n64 saves the day. Thank you very much for your assistance @quicksilver
