Hi everybody.

First of all thanks to all people working to build awesomes emulators.

I dowloaded dosbox svn and i would like to play heroes of might and magic 2. I bought the game on GOG. I past the game folder from windows to my switch sdcard. Unfortunately, when i Launch the exe file game the disc seems to be not present and i don’t know how to mount cdrom. Is it possible to set up correctly this game on my switch ?
Thanks in advance.

You just need to put the CD-ROM files in a folder also, then mount them in DOSBox.

Code:

mount d /path_to_cdrom_files/ -t cdrom

Then you can access them in DOSBox using the "D:" drive letter.

If you're using an ISO file then you need to use "IMGMOUNT" instead of "MOUNT" and the syntax is a little different also.

Code:

imgmount d /path_to_iso/iso_filename.iso -t iso -fs iso

It’s not a very easy way without virtual keyboard.

Is it possible to create a conf file for this game and where should i put this file ?

put the conf wherever you want and load it with load content

rsn8887 · Mar 24, 2019

use a config file (.conf ending), edit the file with notepad on Windows. Load it on Dosbox via Load Content.
use mount command to mount a virtual C: drive for dos games.
use mount command with -t cdrom to mount a virtual D: drive for cd rom files.
use imgmount command with -t iso to mount an iso as D: drive for cd rom iso.

Assuming you have /dosgames/mm2 folder on your sd card with game files, and /dosgames/mm2.iso file:

Code:

[autoexec]
mount c: /dosgames/
imgmount d: /dosgames/mm2.iso -t iso
c:
cd mm2
mm2.bat (or whatever the file is called to start the game)

Assuming you don't have a .iso, but you have the files from the CD in a separate folder called mm2cdrom:

Code:

[autoexec]
mount c: /dosgames/
mount d: /dosgames/mm2cdrom/ -t cdrom
c:
cd mm2
mm2.bat (or whatever the file is called to start the game)

it helps to set everything up on windows (config files, soundsetup etc.) so it works on Windows dosbox with sound etc. Then when the games are setup and work with sound, copy the game files over to the sd card.

Thanks for your help.
Unforunately, it still doesn't work : the game asks me for disc.

I don't know what to do.

I also tried with this command :

imgmount d "\HOMM2.INS" -t iso -fs iso

I saw lines MSCEDEX.... but game still asking me for the cd

If soemone has an idea

rsn8887 · Mar 24, 2019

Do you have an iso or not? .ins is not an iso extension (should be .bin or .iso). Also you are using the wrong type of slash. Read my earlier post more carefully please.

I need help. I can’t open Achievements option in GBA game called Golden Sun without it crashing with the “software closed” message. It works on every other game. I’ve tried replacing the file. What should I do?

I don't have iso but i found this command on gog forum

https://www.gog.com/forum/heroes_of_might_and_magic_series/homm_2_wants_cd_on_boot

I think the command is ok beacause is saw MSCDEX Line when i launch the conf as content.

rsn8887 · Mar 24, 2019

That command was used on a Windows computer. Also you even forgot the dot. The Switch uses forward slashes.

Where is homm2.ins? In the root of the sd card?

If yes use /homm2.ins instead of \homm2.ins

/ is root on Switch, not \

Leave out the quotation marks.

The ins file is not in the root of the card but in the game folder

I feel like it vibrates too strong lol. I turned it off. Great feature though.

The dosbox core on Switch doesn't support CD Audio. But Midi music works just fine. I attached the files to enable it, just unzip and copy over into homm2.

All I did to make music work was that I used my USB keyboard on Switch to start "install.exe." In the menu that appeared, I changed music type from "CD Audio" to "Midi", and I changed Midi and Sound FX driver setting both to "Soundblaster 16." I did that, selected "save and exit", and now both music and effects work together in Heroes of Might and Magic 2.

Heroes of Might and Magic 1 also works great, also just mounting the .gog file as iso. All with dosbox dynarec dynamic core, 10,000 cycles, cycles fixed.

HOMM3 doesn't work (requires Windows).

Someone manage tu run Red Alert in 2018

I wonder if it’s dosbox

rsn8887 · Mar 24, 2019

Two more old RPGs I tested also work really well: Anvil and StoneKeep:

Dosbox dynarec is working so well on Retroarch Switch! I tried Heroes of Might and Magic 1/2, Anvil of Dawn, and Stonekeep. All are very playable with 10k fixed cycles. CD audio in HOMM2 is not supported, but can be switched to midi via install.exe. Thanks to @m4xwdev and fr500. pic.twitter.com/8kdPydzdkj

I can’t stop testing dosbox games they all work so well. Dune 2 also runs great. I will not get much done today, too excited about this dynarec core

need to try more games.

I got this error when trying to launch C&C Red Alert, tried another dump and got black screen
