Dreamcast mvc2 crashing at stage 2
-
Wow.
Thank you guys so much for this information and everything!
I haven’t had the chance to look today, I’m feeling a little under the weather.
The only game I want to play is mvc2, I have no interest in any other Dreamcast game at this point. So if you could give me steps to build this the way you are describing I would appreciate it and I will give it a try.
I wonder if the Naomi emulation using the reicast core for the arcade rom has the same issues? I’ve seen some people on YouTube running the Naomi emulator arcade version of this game and my ultimate goal is to get that up and running in a dedicated cabinet...at some point. For now I’d just like to be able to play this version
So if you could list the steps that need to be done to get this operational I would appreciate it very much. I will post the requested information from my end if I don’t feel like a walking corpse tommorrow.
Edit: does anyone have any idea when they will add the fix to the master branch?
Thanks again!

Ok, feel better. Here you go..
First, open a terminal window on the pi, and run the following:
cd ~/ git clone -n https://github.com/reicast/reicast-emulator.git cd ~/reicast-emulator/ git checkout 49046aecd9e87d6ba8c1508ad6222526842bbacd cd reicast/linux/ make -j4That will start the build, and it will take a few minutes to complete. When it's done, you'll have the command prompt available to you again in the terminal window. If the build was successful, you should see a file called 'reicast.elf' when you run..
ls -al..from that same terminal window. That's your new reicast binary, which needs to be placed in the reicast installation directory. To do that, run the following:
sudo cp reicast.elf /opt/retropie/emulators/reicast/bin/reicast_49046aeAt this point, you'll have 2 copies of the reicast binary in /opt/retropie/emulators/reicast/bin/: the new one you just copied over, and the one that retropie_setup.sh installed for you (which is just named 'reicast').
If you can get to that point, then run..
cat /opt/retropie/emulators/reicast/bin/reicast.sh cat /opt/retropie/configs/dreamcast/emulators.cfg..and copy/paste the resulting output from each cat command. Then I can send you the remaining steps.
Edited: Just needed to correct the path to reicast.sh shown above
-
I will do this when I get home and post it. Thanks!

Ok sir I made it up to the very end where you are asking me to run these two lines.
It says not such file or directory, however.
My reicast.sh is not in the reicast root directory, it is in reicast/bin/reicast.sh
Ok I ran the cat on it from the bin directory, but the output is enormous and I’m not sure how to get it from the pi to here on the forums unless I take a picture of it or something.
edit:
Ok I think I'm following what your doing here. I had to google what the cat command did but here it is.#!/usr/bin/env bash # This file is part of The RetroPie Project # # The RetroPie Project is the legal property of its developers, whose names are # too numerous to list here.

@tackett1980 Sorry about that.. yes, the reicast.sh in the reicast bin folder is what we want. To complete your journey toward the dark side, do the following:
cd ~/ sed 's/\/bin\/reicast\"/\/bin\/reicast_49046ae\"/g' /opt/retropie/emulators/reicast/bin/reicast.sh > ~/reicast_49046ae.sh chmod +x reicast_49046ae.sh sudo cp reicast_49046ae.sh /opt/retropie/emulators/reicast/bin/ sudo cp /opt/retropie/configs/dreamcast/emulators.cfg ~/emulators.cfg.old sed '/reicast/ i reicast-for-mvc2 = "/opt/retropie/emulators/reicast/bin/reicast.sh omx %ROM%"' emulators.cfg.old > emulators.cfg sudo cp emulators.cfg /opt/retropie/configs/dreamcast/That's it. So now launch mvc2, and press a button on your controller as it's launching. This will take you to the menu where you can select a specific emulator for this ROM. Select 'reicast-for-mvc2'.
Also, note that if you install/update any dreamcast emulators via retropie_setup going forward, these custom settings will be overwritten. So maybe keep some copies of reicast_49046ae.sh and emulators.cfg in your home directory.
-
Alright friend. I thank you for all this hard work with me.
I did this, and it does come up in the select emulators, but it won’t boot. Just crashes back to the emulation station rom select screen.
I probably screwed something up somewhere
-
hm.
cat /dev/shm/runcommand.logTake a look at the log. Then launch the game with your default reicast emulator (reicast-audio-omx, and we can compare the logs.
-
OK,
here is the runcommand with the default reicast.

@tackett1980 - Probably worth taking a look at the modified files..
cat /opt/retropie/emulators/reicast/bin/reicast_49046ae.sh cat /opt/retropie/configs/dreamcast/emulators.cfg..just to make sure they look right. Also..
ls -al /opt/retropie/emulators/reicast/bin/..would confirm that the new binary is there, and it's not 0 bytes in size.

Ok this is the issue, the reicast_49046ae.sh is 0 bytes.
LOL what did i do wrong?
-
Maybe the reicast.elf wasn't built..
ls -al ~/reicast-emulator/reicast/linux/If you don't see it there (or it's also 0 bytes in size), then try the build again (i.e. the steps up to, and including, 'make -j4'). When it finishes, scroll up in the terminal window and look for ERROR or WARN messages.

ok I will run it again. The elf file is indeed there and it is about 50mb.

Yeah, 50MB is in the ballpark.. as long as it's not zero. Mine is about 60MB, for reference.
When the new build finishes, try these steps to copy it to the reicast bin folder instead:
cd ~/reicast-emulator/reicast/linux/ cp reicast.elf reicast_49046ae chmod +x reicast_49046ae sudo mv reicast_49046ae /opt/retropie/emulators/reicast/bin/ ls -al /opt/retropie/emulators/reicast/bin/After you run that last 'ls -al' command, the output should look like this:
$ ls -al /opt/retropie/emulators/reicast/bin/ total 120972 drwxr-xr-x 2 root root 4096 Feb 26 09:43 . drwxr-xr-x 4 root root 4096 Feb 25 14:34 .. -rwxr-xr-x 1 root root 61917760 Feb 25 15:37 reicast -rwxr-xr-x 1 root root 61918028 Feb 25 16:59 reicast_49046ae -rwxr-xr-x 1 root root 1263 Feb 26 09:43 reicast_49046ae.sh -rwxr-xr-x 1 root root 10956 Feb 25 14:34 reicast-joyconfig -rwxr-xr-x 1 root root 1247 Feb 25 14:34 reicast.shThe 'reicast' and 'reicast_49046ae' files should have the same permissions (-rwxr-xr-x), and be approximately the same size.
I'll check up on this tomorrow. Welcome to the wild west.

Thanks for all your help, I am also going to hit the sack for the night.
I have two questions:
1: would this be easier to accomplish some of this in winscp when possible rather than doing it all with terminal commands?
2: would it also be easier to just uninstall the reicast entirely and build this one as the soul emulator? If I cant get the game working I will likely just delete the entire thing anyway so it doesn't really matter. I have no other dreamcast games Im interested in.
Again, I cant thank you enough for your help. You deserve like a fruit basket or something. If this forum had a rep feature or something Id be repping you into oblivion at this point.
-
No prob. Thanks for reporting it, because I've leared a lot. This game has issues in all 3 dc emulators. I still need to write up a report for the flycast folks to review.
-
Oh yeah, if you have winscp, you can just copy the emulators.cfg and reicast_49046ae.sh to your windows machine, edit the files there in Notepad++ (or whatever text editor you use), and then scp them back to the pi. I'm listing the terminal commands for my own benefit, as I'll likely refer back to these steps at some point.
-
I doubt your existing reicast installation is causing the issue you're having now. It just seems like you have different permissions than me, which didn't allow you to copy the reicast.elf to a new name (or to a location that's owned by the root user). So maybe just try the new steps I mentioned in my previous post.
-
-
Ok I will give this all another shot when I get home.
-
Ok, I think I’m just to stupid to do this correctly.
My permissions look the same, all the files are there and nothing is zero bytes anymore except now when I boot up to select emulators there are like 3 “reicast for mvc2” emulators to choose from and all 3 of them load no information according to the run command log.
I think I may just give up and uninstall the Dreamcast emulator all together.
Edit:
Hell with it, the original reicast won’t load either just crashes back to emulation station. -
@tackett1980 - hm.. the 3 mvc2 emulator options is wrong, for sure. Based on what you posted before, I think your files need to look like this:

-
Also, if it still doesn't work after matching your .sh and .cfg files to the ones I just posted, maybe just try running the command right from the terminal on the pi:

@tackett1980 - Gah.. another typo in my previous post.. please look at my latest output for reicast_49046ae.sh. That should be correct. The last 5 lines is really all you need to look at.
