Thanks guys, my Friend borrowed the pi, so I will post The Result in a few days.
Thanks you very much.

Perfect. Thanks. That was the folder I didn't know the location of. It did have hard coded video aspect and overlay. All is good now.

@quicksilver I have 6 button setup working on both emulators as of now. I found the settings you mentioned in Mortal Kombat II but changing them made no difference. I went over everything on my setup and was stumped. I booted up a fresh image, completely up to date, configured my SNES and Xbox controllers and put on my Sega games only. I made the changes to the respective config files and presto it works. After changing the setting you pointed out that I missed earlier in Mortal Kombat. I don't know why my original setup was not working. It has to be something I modified but I haven't found it. Thanks for you help and if I track it down I'll let you know.

Update: I think I found the problem. When I updated in the morning I did both binary and source, I've never used source before. It wrecked my controller configurations. It had my generic SNES listed as generic and just SNES, and the Xbox controllers were listed as generic Xbox, the original config, and Xbox 360 Pro. Every game I launched listed the two controllers I had connected twice and then worked in piece. Not sure why updating from source would do this as I have updated from binary and it was fine. In the future I will probably unplug all controllers and use the keyboard for updating.

@quicksilver Yeah, I did the same. Took those that were already converted, the rest I went for bin/cue formats. Converting myself never went right.

Thanks for the guide! I'll give it a try later. So far I'm only interested in PCE-CD and Sega CD games.

I got it to work placing cue and bin files into the sega32x roms folder and using lr-picodrive. After launching game, hit selct-x to bring up Retroarch menu. Scroll down to "Options" and set Input device 1 to 3 button pad. and Input device 2 to "None".

@saccublenda Ive found switching between discs was an issue when select-x to retroarch menu When using bin. and .cue roms. Try using just .iso roms for mutli disk games like night trap and ground zero texas. Worked for me

Thank you for all the help, everyone. I managed to compress my entire collection into CHD files. Much cleaner, and much smaller space-wise. And, they all work...except for the Sega-CD 32x games (there's only three or four of those). I guess I have to do some more homework on that one.

Not all my images were bin/cue. Getting them to be bin/cue so I could convert them to CHD was tedious and sometimes frustrating, but I got it done.

Thanks again.

@dv8mad You need to enable SSH first before using WinSCP - see the docs https://retropie.org.uk/docs/SSH/. After you enable it, then you can use WinSCP and transfer the CD images.
But you'll get the same result if you transfer the files over file shares, copying them via file shares in \\retropie\roms\segacd. Make sure that the files have the proper case, i.e. .cue vs .CUE, and the .cue file (which is a normal text file) also has inside the correct .bin filename. Remember that Linux has a case sesitive filesystem.
Once you have copied the files, restart Emulationstation and see if the system shows up with the games. If they don't, check the log in /home/pi/.emulationstation/es_log.txt via WinSCP and see if you get any errors there.
More information about Sega CD games you find in the docs - https://retropie.org.uk/docs/Sega-CD/.

Okay, I'm not sure what happened, but suddenly Genesis games work. I'm not sure if it was bad roms like @mitu said or if it was bad naming conventions on my end (changed both at the same time), but seems to function now either way.

Thanks again everyone for the help!

@mitu Dang, The cue file name was uppercase in the bin file names. Made it match the real file name and its all good. Pico drive must be just looking for a bin file and ignores the cue name.

@buzz

Oy......sorry I should have known that (it just slipped out). I got overexcited. Sorry that I’m off to a bad start :(

Update:

I found these instructions and tested them:

link text

What I did for USB memory stick was to input these settings to be used (settings for regular HDD might be different):

sudo hdparm -B 255 /dev/sda sudo hdparm -S 0 /dev/sda

I first tested them for 30 mins in Driver 2 and then for about 20 mins in Gran Turismo 2 and then again with Driver 2 for 5 minutes. With the Driver 2, I didn't encounter a single freeze in 30 mins. Then I went for the GT2. There I withnessed 3-4 freezes overall. Then I went back to the Driver 2, because I started to think, that maybe heat or something triggers the freezing issue. But on the second tryout with Driver 2, no freezes at all.

So now I'm wondering, that could it be about the emulator software or does the game have differences in data loading methods. Needs to be further investigated and someone else could try with that guide I linked.

Update: I now discovered, that there is audio cuts during the GT2 Arcade Disc's demo, that starts rolling after a while when sitting on the main menu. Maybe the issue could be related to that as well, sync problems you know.

@chipsnblip Sorry, thanks.

@Jiryn Yeah. If your computer is on the same network as your Pi (and the Pi is running) you can access it via your web browser of choice. I've had it activated for so long I'd forgotten how to make it work, thankfully @ETAPRIME has that covered:

Once active, you can drag-and-drop your BIOS files via the web page. If they're not what RetroPie is looking for it'll tell you then you can seek another source. Saves the time and hassle of repeatedly booting up your Pi to see if you've fixed the problem.

@Shmeter.man are you using a thumb drive to put the bios on? There are issues with the sega cd bios' and that method. Use something like winscp to put the bios files on.

@Willreaper Read this to answer your questions https://github.com/retropie/retropie-setup/wiki/Sega-CD
Dreamcast is hit or miss, and fat chance on the Saturn.

Everything is working now I just need to copy bios directly into sd card.

@meleu

I think RetroArch doesn't care about extensions...

Jeezy Creezy.... It was just that easy.

Ahhhhhhh well. At least when I'm wasting a ton of time and the answer is just this simple at least I'm learning new things, right?

I absolutely can't believe the best answer was changing .bin to .cue. Works perfect for launching the game, and it shouldn't give any problems with our script either.

Thanks everybody!

Thanks. That fixed it.

@NovaTheMighty

Unfortunately, there have always been emulation issues regarding this game. Before 2004 it was completely unplayable on any emulator past the abandoned factory. It might help to raise this issue over at the libretro forums, as they're more likely to have insight into the nuts and bolts of this.
