Getting GOG cd games to run on Retropie

[mitu]

@squiike No. The video you posted is about a different thing - Windows emulation. AFAIK HOMM3 is Windows only, there is no DOS version. HOMM2 works with Dosbox - the GOG version comes with Dosbox to run the game, the same Dosbox you have in RetroPie. Ignore the video.
I have nothing else to add to my original instructions - /dev/shm/runcommand.log only exists after you run a game, it's empty by default. So if you want to see the log, then first run the game and then try to get the log file.

@mitu Got it. I cant upload text files, sorry about the mess. I'll edit it better once i know how.

@squiike What does the DosBoxDaggerfall.conf file contain ? Can you paste the file's contents, surrounded by code blocks delimiters (```).

@mitu Not sure how. I copied all and pasted. starting 1 on [sdl] and 66 on exit

Lines in this section will be run at startup.

imgmount d "/home/pi/RetroPie/roms/pc-data/homm2/homm2.inst" -t iso -fs iso
c:
cls
heroes2.exe
exit

[mitu]

@squiike I see. I'm sorry, but I don't know why this doesn't work for you. However, the important line for the CD to work is

imgmount d "/home/pi/RetroPie/roms/pc-data/homm2/homm2.inst" -t iso -fs iso

This will make the tracks in the music folder appear as a music CD in Dosbox.

@mitu I tried to download another version. This time a free(not GOG). Same issues. I can run it from shortcut. But as this is free and half the size(about 200 mb) maybe others could try and post if they are successful :)

@mitu Even though it didnt work, thank you for being patient and trying to help a noob out :) +1

@mitu I actually managed to get Daggerfall to work. I have one guestion on Heroes2.

When i type; imgmount d /home/pi/RetroPie/roms/pc/heroes2/homm2.inst -t cdrom

Heroes2 in pc folder is a new one i made now(not the one from last session) and the capital letters or lower cases are correct. I get "MSCDEX: Failure: Invalid file or unable to open. "
When i go into the folder in dosbox the homm2.inst is named HOMM2~1
Do i need to type that instead? so ....homm2~1.inst -t cdrom ?

Also, i do not know if i am able to make the ~sign on my keyboard in dosbox or console.

@squiike said in Getting GOG cd games to run on Retropie:

Do i need to type that instead? so ....homm2~1.inst -t cdrom ?

I don't think that's it, but you could just rename the file to homm2.cue and re-try with this name. But the command that worked was not as the one you tried, it was

imgmount d "/home/pi/RetroPie/roms/pc-data/homm2/homm2.inst" -t iso -fs iso

[Squiike]

I managed to get another version of homm2 to work. So now i got both Daggerfall and Homm2. Homm2 lags abit but is playable. Anyone, feel free to PM me if you have the same issues i had :)

[mitu]

@squiike It would be nice to explain the setup here in the forums, just in case someone else wants to replicate it. PMs are not enabled in the forum.

I have simillar issue, you must mount gog file instead of inst.

There is also the Free Heroes 2 engine (Fheroes2) that you can compile on Raspbian and make it work. I have succesfully tested it both in Raspbian desktop(X11) and in Emulationstation. It runs best in Raspbian desktop(X11) since running it in Emulationstation is too slow in speed.

I might as well create an install script like i did with Hexen 2 Hammer of Thyrion source port.

By using the Free Heroes 2 engine you will not be needing dosbox as this will run Heroes 2 natively through the source port.

Let me know if i can be of any help to you.
