Dreamcast mvc2 crashing at stage 2
-
@quicksilver I'm on a pi4.. very recent image from about a month ago.
-
@rejesterd do you have any more info about the crash? I've not heard of a crash from this game in ages, but would love to see the stdout after it crashes if you can snag it. To note, I pushed a fix a few nights ago that addresses a silly shader compilation error (literally, a typo) that'd been hanging around for a few weeks and effected some games with fog.

Then a binary compiled for the 3b model won't work, since it uses the legacy video drivers.
-
I’m on the way home from work I can try to get the information you need if someone can walk me through how to obtain it.
-
@tackett1980 he's referring to the crashing behavior on redream not reicast.
-
Well, I gotta quit for the time being (I'm so sick of this game now lol), but here is what I've learned.
It consistently crashes in reicast every time when you reach the second stage (and in rare instances, it will crash even before then). The runcommand.log shows:
Parameters: Executing: /opt/retropie/emulators/reicast/bin/reicast.sh alsa "/home/pi/RetroPie/roms/dreamcast/Marvel vs. Capcom 2.chd" 640 480 ALSA: underrun occurred ALSA: underrun occurred /opt/retropie/emulators/reicast/bin/reicast.sh: line 35: 7380 Trace/breakpoint trap "$rootdir/emulators/reicast/bin/reicast" "${params[@]}"Note that if I run the game in reicast with sound disabled, the underrun messages go away, but the crash still occurs and the last line in the log is the same. So I don't think it's related to audio. I added these details to issue #1684.
In redream, the crash is not as consistent as you advance through stages (I made it to stage 3 many times and the game never crashed). However, I am able to get redream to crash pretty consistently right away if I just rapidly press B to select my characters and the game mode (turbo or normal). Doing that rapidly causes a crash before match 1 begins. So I reported that to inolen as issue #967. Hopefully he can fix it for redream. Not sure how much attention it will get from the reicast folks, as it's an old issue.. seems like they thought it was fixed back in July, but apparently not (or this is just a new crash profile).
Cheers.

@inolen I just reported it (issue 967). Thanks.

My pi3 has an older version of reicast and I was able to make it to the 2nd stage without crashing. You might be able to take my reicast binary and swap it out on your pi.

Place it in:
/opt/retropie/emulators/reicast/bin/I would recommend backing up your reicast binary first before replacing.
I replaced my binary with yours, however yours is different.
On mine if I push start reicast, it sends me to a black screen that I can enter options for reicast itself or boot to the Dreamcast bios.
Yours does not give me that option. When I push start reicast it goes directly into the Dreamcast bios menu.
Why?
-
@tackett1980 Its older an older version than yours
-
Oh ok, how do I get it off of what I assume is in interpreter mode? It’s super slow.
-
@tackett1980 Im not sure why its running slow, could be some incompatibilities with your current settings IDK. Its not slow for me.

In ~/.reicast/emu.cfg, you need to make sure Dynarec.Enabled = yes. If it's set to 'no', that means it's in interpreter mode.
-
@tackett1980 Can you post the contents of your emu.cfg?
-
Yes I will do so when I get back today.
-
I actually can’t find this file anywhere....
If I go /home/pi
All I see is

@tackett1980 Try
/home/pi/.reicast, it's a hidden folder. -

four edits I think I got it finally. -
@tackett1980 I'll compare with my settings when I get home but I think some of my settings are different from yours...
-
At this point I think the issue is that it isn’t able to access to VMU save data.
I came to this conclusion because I found a existing save, using a VMU writer, I wrote that to an new vmu_save_A1.bin file and replaced it.
When I loaded into the game it says “file created” like it never accessed the file.
So I’m partly convinced that if for some reason it is able to access the save data it won’t crash any longer.
But my wife will tell you that I’ve been wrong before...
Man if I could just get this working I think I’d be satisfied. It runs remarkably well.
-
Ok I can officially say that it is not reading any save data.
Every time I load the rom it says
“File created” or something of that nature even though there is save data available.Is there an error log file created somewhere that I can maybe dump on here to have you super smart people take a look at?
