Dreamcast mvc2 crashing at stage 2

tackett1980

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

rejesterd

hm.

cat /dev/shm/runcommand.log

Take a look at the log. Then launch the game with your default reicast emulator (reicast-audio-omx, and we can compare the logs.

@rejesterd

OK,

here is the runcommand with the default reicast.

actually its blank, geez I screwed something up.

rejesterd

@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?

rejesterd

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 .

-rwxr-xr-x 1 root root     1247 Feb 25 14:34 reicast.sh

The '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.

@rejesterd

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.

rejesterd

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.

tackett1980

@rejesterd

Ok I will give this all another shot when I get home.

tackett1980

@rejesterd

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.

rejesterd

@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:

I would at least try those before quitting, because the resulting runcommand.log indicates that the reicast command isn't even being executed. Probably not you.. more likely a typo by me from earlier.

rejesterd

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:

/opt/retropie/emulators/reicast/bin/reicast_49046ae.sh oss "/home/pi/RetroPie/roms/dreamcast/Marvel vs. Capcom 2 (USA).gdi"

..and see what you get.

rejesterd

@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.

tackett1980

@rejesterd

Ok I’ll Go back and give it a shot. I actually deleted everything already but that’s Ok might make it better to just start from scratch again.

rejesterd

@tackett1980 Hope it'll be worth the effort this time, as the hard part is typically getting the .elf to build (and you were able to do that). Just seems like a config issue now.

tackett1980

@rejesterd

Roger that. Do I need to reinstall the standard reicast or just start manually building again like we were?

rejesterd

@tackett1980 Yeah, reinstall reicast from the retropie setup script first. There are other files/links that still need to be there for the custom-built binary to work.

tackett1980

@rejesterd

Ok will do.
