Dreamcast mvc2 crashing at stage 2
-
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:

Probably not you.. more likely a typo by me from earlier.
-
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.
-
@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.
-
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.
-
@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.
-
Roger that. Do I need to reinstall the standard reicast or just start manually building again like we were?
-
@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.
-
Ok will do.
-
Hello,
Sorry this took so long to get back to but here goes.-I reinstalled the retropie reicast
-I followed what we did to begin with at the beginning of this thread to build the reicast.elf.
This was all successful.I continued our steps and in the end I still ended up with three “reicast for mvc2” emulators.
I chose one and booted and this time it booted, however. It still crashed at stage 2.
I then looked to edit both the files in the way you showed me.
The 49046ae.sh file is no longer 0kb. It is 4. The text appears identical to what you posted.
However the emulators.cfg is where the three reicast for mvc2 settings were. This cfg had the reicast for mvc pointing toward the standard reicast binary , which explains the original results. I then made this like the one you showed which is now pointing toward the 49046 binary and then tried to boot the rom.
This one will not boot, crashes back to emulation station. Hold on I will copy the run command log.

This might be due to a missing patch that's required for Pi3 (but not the Pi4). But this..
EGL Error: eglInitialize failed
..could mean you have a different version of the bios files than I do. To confirm, just get the md5sum value..
pi@raspberrypi:~ $ md5sum ~/.reicast/data/*.bin e10c53c2f8b90bab96ead2d368858623 /home/pi/.reicast/data/dc_boot.bin 764b39e3d3fa15f0156b9595ec68416d /home/pi/.reicast/data/dc_flash.bin eff5d8cead94b9e62b9b12817fa585af /home/pi/.reicast/data/dc_nvmem.binIf your values for these files are the same, then I would say this is not going to work on the Pi3. I'm not sure you need to worry about dc_nvmem.bin (as I think that's installed by flycast). But the other 2, should be the same as mine.
I can tell you for sure, it works on the Pi4. I would like to take a closer look at the retropie way of installing patches, because that's the only missing piece I can think of at this point.
-
Wait.
Those paths doesn’t look right.
My reicast bios are in
Home/pi/RetroPie/bios/dcNot the hidden folder.
-
Oh that's interesting. Note that .reicast is just a symbolic link (not a real directory). The real directory is /opt/retropie/configs/dreamcast/data/. As far as I know, that's where reicast looks for the *.bin files. I think it's flycast that looks to ~/RetroPie/BIOS/dc/. I would try copying the *.bin files from ~/RetroPie/BIOS/dc/ to /opt/retropie/configs/dreamcast/data/.
-
..and it does look like there's a slight difference in the nvmem bin file between reicast and flycast:
pi@raspberrypi:~ $ md5sum ~/.reicast/data/*.bin e10c53c2f8b90bab96ead2d368858623 /home/pi/.reicast/data/dc_boot.bin 764b39e3d3fa15f0156b9595ec68416d /home/pi/.reicast/data/dc_flash.bin eff5d8cead94b9e62b9b12817fa585af /home/pi/.reicast/data/dc_nvmem.bin pi@raspberrypi:~ $ md5sum ~/RetroPie/BIOS/dc/*.bin e10c53c2f8b90bab96ead2d368858623 /home/pi/RetroPie/BIOS/dc/dc_boot.bin 764b39e3d3fa15f0156b9595ec68416d /home/pi/RetroPie/BIOS/dc/dc_flash.bin ec6f52b681b2220d0c363abec77af8f2 /home/pi/RetroPie/BIOS/dc/dc_nvmem.binBut I would still try copying all 3 dc_*.bin files to ~/.reicast/data/
-
Copy or move them entirely? As far as I know the official reicast build looks for them in the /bios/dc folder. I originally had a hard time getting reicast to even load with them in any other directory.
I wonder if the pi4 build wants them in a different directory or if the dev reicast does.
-
@tackett1980 Yeah, I think you're right. In looking back at the reicast.sh, it does seem that it's looking to ~/RetroPie/BIOS/dc/. Maybe I have the bin files under ~/.reicast/data/ because I followed the wiki page when I was originally setting everything up.
The other interesting thing is that you get a LOT more output in your runcommand.log than I do. I only get about 3 lines. Not sure why that is. So I guess just compare your md5sum values in ~/RetroPie/BIOS/dc/ to mine. Those should be the same, regardless of us being on different Pi models.
Copying the files won't hurt anything, so you can try that too. Copy them, don't move them. If it still doesn't work, the last resort (as I know all too well from my job) would be a join.me session.
-
Ok so there are short cuts in my data folder to both the bios files that points toward the bios/dc dir.
The nvmem is also there, but it’s an actual file and not a shortcut.
Does anyone have this working properly on pi3? Surely I’m not the only one having this issue.
