Dreamcast mvc2 crashing at stage 2
-
@tackett1980 Sounds good. Also try deleting this file if it exists..
/opt/retropie/configs/dreamcast/data/Marvel vs. Capcom 2.state
Wondering if that became corrupt somehow and is affecting things.. not likely, but possible.
It is strange to me that the unlocked characters cheat is apparently enabled for you. I actually don't know how cheats can be enabled for reicast yet.. I actually asked that question on the forum not too long ago. So that will be another thing to take a closer look at.
One thing I'm still not understanding is how your old emu.cfg file is being preserved, if you've removed then reinstalled reicast from source. Seems like that file should be replaced with the default one. But that's just an assumption, as I actually haven't tested that specific issue. But I'll scroll up and find your emu.cfg that you posted earlier and take a look.
-
That’s because I change the options back to the way I had them. If I keep the settings default the game runs so poorly that testing it is impossible.
I can leave them default and post the file contents but I can’t test the game.
Oh where is the build log located so I can post it when I do this again? Never mind I see it sorry.
-
Ok I tried it again and it failed to build the .elf file.
here is the build log.
-
Looks like a toolchain/linker issue. Can you also share ~/RetroPie-Setup/tmp/build/reicast/reicast/linux/Makefile?
-
-
Ok, it seemed to like the alpha branch better (since you were able to manually build it before). So just open ~/RetroPie-Setup/scriptmodules/emulators/reicast.sh in a text editor, and find this section..
function sources_reicast() { ## gitPullOrClone "$md_build" https://github.com/reicast/reicast-emulator.git alpha 49046aecd9e87d6ba8c1508ad6222526842bbacd gitPullOrClone "$md_build" https://github.com/reicast/reicast-emulator.git stable ## applyPatch "$md_data/0001-enable-rpi4-sdl2-target.patch" ## applyPatch "$md_data/0002-enable-vsync.patch" ## applyPatch "$md_data/0003-fix-sdl2-sighandler-conflict.patch" }Then change it to:
function sources_reicast() { gitPullOrClone "$md_build" https://github.com/reicast/reicast-emulator.git alpha 49046aecd9e87d6ba8c1508ad6222526842bbacd ## gitPullOrClone "$md_build" https://github.com/reicast/reicast-emulator.git stable ## applyPatch "$md_data/0001-enable-rpi4-sdl2-target.patch" ## applyPatch "$md_data/0002-enable-vsync.patch" ## applyPatch "$md_data/0003-fix-sdl2-sighandler-conflict.patch" }Then try removing reicast and re-installing from source using the retropie-setup menu.
-
Trying this now.
-
-
Alright, it's the same failure. So do the git hard reboot again, then re-install reicast using the default retropie-setup (from source). Then get the build log from that (which should be successful). We'll have to compare it to the bad build. Certainly something is different about the Pi3.
-
well, im not sure if this helps, but I tried backing out of the retropie setup and accidentally hit install again and it actually worked and it did it very quickly. Heres the build log for whatever that was.
Im uninstalling and reinstalling from source again and ill post that build log in a minute.

Ignore my last post that build was an install from binary.
here is the actual build log you are looking for that functions:
-
@tackett1980 I've asked about this on the reicast discord server, since rpi3 seems to have trouble with the newer jit-related features (which, not surprisingly, were added to address this very issue with crashing). But again, I don't see any technical reason why it shouldn't be able to build on rpi3, so hopefully we'll get it working with a little guidance from the developers. I'll let you know what I find out.
-
Sure thing. I appreciate it sir, thanks for all the help to this point.
-
@tackett1980 I just realized I forgot to ask for the output when you run..
md5sum ~/RetroPie/BIOS/dc/dc_*? Just want to be sure we're working with the same bios files.
What bugs me is that you were able to build the reicast.elf before manually (using my original steps). But it wasn't launching the game, and was instead crashing back to emulationstation. So I'm wondering if it would have worked if you were using different bios files at the time.
-
-
@tackett1980 Yeah, your dc_flash.bin is different than mine, and you don't have dc_nvmem.
pi@raspberrypi:~ $ md5sum ~/RetroPie/BIOS/dc/dc_* e10c53c2f8b90bab96ead2d368858623 /home/pi/RetroPie/BIOS/dc/dc_boot.bin 73a35e6844a89cda035943f03ad7306b /home/pi/RetroPie/BIOS/dc/dc_flash.bin ec6f52b681b2220d0c363abec77af8f2 /home/pi/RetroPie/BIOS/dc/dc_nvmem.binDue to forum rules, I can't share a link to these, but I would bet if you search Google a bit, you'll be able to find them. If you can get the same bios files installed, I think that previous reicast.elf you built will work.
-
On the pi3 the dc_nvmem is required to be in a different path. It is in the directory we talked about previously with the shortcuts to the other bios files. I have the file it’s just in the other directory.
I’ll google around and see if I can find the files. I’m going to be moving to a pc build soon so all of this will be moot, but I would like to get this thread closed up with an answer for future users who stumble on it.
-
@tackett1980 Cool.. you know, I'm just gonna say the difference in bios files might be a wild goose chase.. so only search for mine if you're really bored :P Hopefully the reicast folks will address the build issue with the stable branch on rpi3.
