My games do show up tho but I am unable to launch them...

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?

Skum1988

@Thorr69 Now I am pressing reboot. But before I unplugged the device regularly because I didnt realize that you can use a keyboard to reboot RetroPie

CommicBook has a MD/Genesis logo, so that shouldn't be an issue. Try re-installing the theme and check afterwards.
