This info is covered already in the Docs - including where to copy the BIOS files, since RetroPie already configures RetroArch. Note that some games have issues when the 'boot to BIOS' option is selected in lr-pcsx-rearmed.

@Smythius said in Intellivision was working and doesn't now.: I think quicksilver may have found your issue as your BIOS files should be in /home/pi/RetroPie/BIOS/ and your setup appears to want them in your roms folder. You could try copying them there if they are not already and see if it works. My Intellivision retroarch.cfg just points to the global one in /opt/retropie/configs/all/retroarch.cfg I dont have any custom values in it other than the input remapping (maybe you have something else?) in the global file you should have system_directory = "~/RetroPie/BIOS"

@mitu thank you Mitu!!! 👍😎 The BIOS Files are in the rom folder of "AdvanceMame". It were about 40, which i renamed to (i.e.) "ZZZ BIOS - CPS1" to get them all together on the bottom of the gamelist and hide them. As mentioned the only two ones that are still visible since a couple of weeks in full mode are Akklaim PSX and Naomi. It does not really disturb me!!!, but i will Post the filenames as soon as i am back on my Pi 😉

@PCKid The .cfg files don't go in the ROM folders. Remove the /home/pi/.atari800.cfg file, make sure you've copied the right BIOS files and then start a game.

@Efriim I will share if I manage to get it to work though, I couldn't get the controller to get into the "Settings" initially till I found this thread and I followed it through. Now the challenge is to get it to work in the games.

@RetroDuck Re-read the forum rules - there's no download links to ROMs or other copyrighted material.

@rafioso24 There's no asking/sharing copyrighted material in the forums - https://retropie.org.uk/forum/topic/2/forum-rules.

@simpleethat I tried it a few times to try and get to the memory card manager, I didn't even realize that it was because of an .m3u. I always turn it off, like its a big no, or I'm in a hurry to boot my game. And now I'm kind of interested, with the same interest that we get when we first turn on our playstations. I'll leave it on and see what I find. I half remember the playstation bios telling you what bios you're using but, I must have imagined it as all I ever see is PCSXtm. On my Raspberry pi 2, the BIOS screen was difficult to get the sound perfect without any drops. I spent a while changing the audio freq, but then overclocking almost got it to perfect. Random: If you leave Final Fantasy IX on for over 99.59.59 then the clock resets and changes color, mine was red, I don't know what impact this has on the game.

@mitu oh sorry. ok then thanks

@Thorr69 said in The Neo Geo emulator does not find the bios: @Rubencn1234 Put it in the same directory as the roms. If you put it in the BIOS directory, it doesn't seem to find it. I had to put it in the roms directory (with the correct name) in order for it to work. Which emulator are you using? FBA works fine without "neogeo.zip" in the roms folder. I have it just in the BIOS folder. @Rubencn1234 Check to make sure you have the right BIOS file. neogeo.zip needs to be ~1.5 MB and CRC-32 should be 20F12195

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

I use to set bios roms as “hidden” (you can do this in that page containing each file info: name, producer, cover path, year of release, and so on...) you will still see hidden files in “normal” use, so I switch to kiosk mode (where hidden files are not shown) when have to do some modification or trick, I easy switch back to “normal” mode by a short controller combo password (default is up up down down left right left right A B) and then when done switch back again to kiosk mode. this way everything works great, and I am also sure that casual users (friends, or my kids too) can’t mess up with my system (kiosk mode disables almost all configuration switch and options)

@John_RM_70 Aha! The key was renaming the BIOS file to dragon32.zip! (From d32.zip.) Many many thanks for that. Now I have the Dragon OS screen showing, if I could only figure out why the A key won't work (leaving me only able to type "CLODM") I'd be sorted...

Thanks for the reply i'll post a log tonight. i'll try fs-uae too :)

Oh thanks guys, I putted my bios on the BIOS folder and not in the BIOS-dc folder, now everythink work grate

Unfortunately, the retroarch guys say a pi port can't be done due to the limitations of the pi's gpu. Not sure if that'll change.

So, thanks for the help. I found on my computer the file SMS BIOS V1.3 (UE) [h1].sms. I started it up. It showed the Sega Master System startup screen, then it went to the Snail Maze without any prompting from me. So, thanks for the help everyone. I feel 14 years old again :D

@tuki_cat use the RetroArch RGUI and choose the options in the configuration. Or, modify the global config file in ’/opt/Retropie/configs/all’. Make sure you don't have config_save_on_exit options configured.
