I know that conf files can now be started directly from the ES. Nevertheless, the question, if I store a dosbox.conf in the directory of the respective game, will it be used and read automatically (e.g. when the exe is started)?

No, it's not going to be read automatically.

If I use cycles=auto, will the game be played with a suitable speed or is there a default value for old games like Might & Magic 1?

Some older games need a fixed cycles, since they assumed the CPU speed will be fixed. You'll have to experiment and see, if auto is not working correctly, then start with a fixed cycles (5000) and add more until it works fine.

Glad you figured it out. Personally I love Dosbox pure. The way it lets you pick files to execute, then set an autostart is brilliant for first install. And the way it autoconfigures a controller map for a good chunk of games. Quite excellent.

@eberhab hi. Good to know it's working and that you were able to sort a lot by reading that thread.

As far as the emulators... Just stick with Pure and Staging. Not sure what's wrong with the pure setup that you get a blank screen. Make sure the .conf options for pure are specific to the emulator version.

Theyre working on yet another fork of DOSBox that looks promising. Keep an eye on that thread. The guys on there are very helpful.

@codafire

Hi. You kinda skipped a few steps in describing the issue. What emulator are you using. What version of Retropie? RetroArch? There are 4 emulator options for Dos and each is slightly different version from each other. So that's really important.

Also... Are you saving the config to the same file or renaming it to a new one? How are you doing this in the emulator? Do you know how to look at the files of RetroPie? If so, what does the .map file say?

@steams71 I messed around with a few different cycles, it somewhat helps...but it just seems this game is on the cusp of the Pi's performance envelope. I found around 16,000 - 18,000 is the best it can do and not have audio issues.

I turned off all the fun caveats of the game and just run it as a clean ice, bare bones game.

I'm not thrilled...but I'm very happy to have it running and playable on my build.

Thanks for the help!

@mitu

That seems to have sorted it! Thank you!

When I stared out I first visited the retropie docs
https://retropie.org.uk/docs/PC/#install-gravis-ultrasound-gus

Which redirected me to this guide from 2015, that suggest using .sh scripts.
Now that everything is working I'll start converting everything over to just using conf-files, and optimizing the games :)

@mitu Thank you so much! Indeed, it was precisely in the full path to the CDROM folder.

As a result, the command looks like this:

[autoexec] MOUNT c /home/pi/RetroPie/roms/pc-games c: cd Rayman MOUNT d /home/pi/RetroPie/roms/pc-games/Rayman/cdrom -t cdrom RAYMAN.EXE EXIT

@jgeibel @wossquee Not sure if you still care about this, but this is now possible by using the new retroarch core dosbox-pure. Just tested it out and now I'm able to get this pinball game working vertically on my cocktail table setup. Now to add 2 flipper buttons on the side so it plays like a real pinball table.

Also note that I had to change the IRQ setting to use IRQ 5 instead of IRQ 7 (the default) to get the sound effects to work.

@quicksilver Oh! Thank you for all your advice <3

@VictimRLSH

I tried:

EMS=true
XMS=true

Still didn't work :(

@mitu I got it... I updated DosBox and it's working good now. Thanks for your input! I always appreciate how fast you reply to these issues.

@ibonihs You could try increasing the cycles to 20000, 25000 etc.

If this doesn't work then could you post the contents of your config file dosbox-SVN.conf at a site like pastebin.com?

solved
the problem was on a corrupt file: INDY.RLE
I had a file with CRC32 1dea93b3, while the correct one is f6fd2362
