Various issues on a new Retropie

@Skum1988 the majority of your issues are related to missing ROMs/folders. You don't need to create manually the folders for your ROMs - they are automatically created by RetroPie when the emulator for the system is installed. The fact that you manually created the folders means that:

the emulator for that system is missing

.. so the folder for the system is not configured in EmulationStation, so the ROMs don't show up.

I'd advise to make sure you have an emulator installed for the systems you want to play and - after you install it - restart EmulationStation. Each emulated system has its own documentation page in https://retropie.org.uk/docs/ which explains what emulators are available for the system, what extra files are needed (BIOS mainly) and what ROM/game extensions are supported.

For Dos games I also transferred the files from my pc folder and while I can see the MS DOS emulator I have no idea how to run my games (not even sure they are detected)

If the emulator is correctly installed, then the .exe /.com file used to start the game (or to install it) should appear in the PC system folder and can be used to launch it.

Last, but not least, when opening a support post, please try to include the information asked in https://retropie.org.uk/forum/topic/3/read-this-first to your post.

@korn16ftl3 transferring games via SSH/File shares is just as safe as the USB transfer and it's even easier/faster.
But don’t you have to know where all the stuff gos and browse to it or cams line?

I’ve always used the usb method because it creates the directories for me and it’s all in the root

@mitu First of all I would like to thank you for your response.

I have read your comment and now most of my roms appear in RetroPie. Everything works fine now except DOSGAMES. As explained I have copied and pasted my dos games into the /pc folder of my sd card but when I try to launch a game I select the launcher of the game and then I get a black screen and the game doesn't launch. My games do show up tho but I am unable to launch them... do I need to select "open DOSBOX'' first ?

It seems complicated thanks ahead

What does this mean ? They don't start or show an error when started ? Can you post a concrete example - what files/folders you copied for a game and what's the error reported in /dev/shm/runcommand.log when you launch the game.

do I need to select "open DOSBOX'' first ?

Not sure what this means - which emulator did you install for DOS games ? Please add the info requested in https://retropie.org.uk/forum/topic/3/read-this-first to your post.

@mitu Rapsberry Pi 4 2+
Power Supply used: official Pi power supply
RetroPie Version Used 4.8
Built From: Pre Made image SF on Retropie
USB Devices connected: controller
Controller used: 8bitdo SNES 30 pro
Error messages received: none
Verbose log (if relevant):none
Guide used: (Mention if you followed a guide) none
File: LTFGAMELAUNCHER.exe!
Emulator: DOSBOX

Some of them actually started if I pressed on the title of the game some of them don't start at all like I will see the dosbox menu and then it will vanish and I will get back to the menu I have noticed that it"s the games that don't have a file with the game's name that don't launch.

The issue seems to be that the game launched reports an error, either it was launched incorrectly (i.e. not starting the right executable) or the game executable needs additional parameters when starting.

Since for DOS there is no one rule for all games you can see what is the actual error is by using the +Start Dosbox shortcut, run a cd <game folder> command and try to launch the game manually by typing the command (game.exe or game.bat). See what is the error reported and try to fix it - maybe a file is missing or you're launching the wrong command to start the game, game needs a CD to work, game expects to be run from a certain folder, etc.

You have to try game by game to see how the game works, but once you find it, you can create a game.conf file which can use used to launch the game. In the game.conf file you enter:

[autoexec]
command 1
command 2
# other commands.
# last command is just exiting the DOS env
exit

where you replace command 1, 2, etc with the commands needed to launch the game.

For instance, to lauch Little Big Adventure 2 by changing to the lba2 folder and executing LBA2.EXE, my .conf file would contain:

[autoexec]
# map C: to the `pc` roms folder
mount c /home/pi/RetroPie/roms/pc/
# simulate a CD drive on D: from the `.dat` file
imgmount d "/home/pi/RetroPie/roms/lba2/LBA2.DAT" -t iso
c:
cls
cd LBA2
LBA2.EXE
exit

Place the .conf file in the same folder as the rest of the PC games (pc) and restart EmulationStation.

@mitu thank you for your reply problem solved

I just have one last question : for the Megadrive emulator I do not get to see the Theme logo when selecting the system only a bland ''megadrive" with no artwork. In addition I do not know how to add a multitap option to enable 4 player games on Genesis Plus emulator

Thanks in advance to you

I don't really understand what is this about ? Which theme are you using and what do you expect to see (instead of the Megadrive logo) ?

In addition I do not know how to add a multitap option to enable 4 player games on Genesis Plus emulator

From the Controls RetroArch quick menu, go to Port 2 Controls and change the Device type to the desired multi-tap device (4-WayPlay, Teamplayer or Master Tap).

@mitu it means that when you are in the menu you see a logo for each system and for Megadrive I just see the regular font without a logo and same in the Megadrive menu its all dark and I dont see the choosen theme.

By the way sorry to disturb but we are also experiencing another issue : when we launch Retropie after a long break (switch off) retropie Emulation station crashes after just a few seconds for some reason and we get an error message. After launching one more time it doesn't crash anymore and we can play but it does crash every time we launch Emulation Station after we switching off for awhile. Do you know what cause that?

Which theme are you using ? The default theme (Carbon) has a MD logo included, but if you've switched to a different theme it may be missing.

This doesn't sound familiar, but please post the exact error message you receive.

@mitu I am using Comicbook maybe that's why

This is the error message that I get everytime I switch on my Rapsberry pi 4 (after not using for awhile). When I reboot however I don't get this message anymore and I can play but it's a bit annoying to get this message every time I launch Emulation station

@Skum1988 Are you doing a proper shutdown? Or are you just unplugging the device?
