N64 crashes after 10 min
-
Seems like if you turn on percentage and vi/s...
The glitches are not so bad and you can make it through them without freezing. -
@bobberella Its probably just incidental. A lot of times I can get through the glitch by not moving. If I keep moving and looking around it makes it worse and usually crashes. At this point I think its out of our hands, Im not sure its something we can fix. I applaud your enthusiasm for digging through configs and testing things though!

@psyke83 has reproduced the issue. We need to debug it though and it could take some time.
-
Awesome.
There seems to be no settings in "advanced mupen64 settings" that do anything besides break the emulator or do unnoticible changes.
I think adding FPS, percentage, and vi/s made it more stable but I have no idea.
Hopefully the fix is soon... :)
The people of retropie thank you.

@buzz thanks for the reply buzz. Do you know if a issue was opened for it on the gliden64 GitHub?
-
@quicksilver not yet - I will open an issue if we can track it down to a specific commit. We don't know that it is a GlideN64 bug (Could be the RPI GPU drivers or firmware for example).
-
Currently testing with the intro for
Legend of Zelda, The - Majora's Mask
letting it run continously. Not seen the problem yet (Running for 18 mins or so). @psyke83 said he saw the issue after 20 mins. Does anyone have a non interactive way of reproducing the issue quicker - so I can leave it running in the background? -
@buzz It has happened for me just loading a level and letting my character stand still for 10-20 mins. However, when the glitch occurs it seems to get worse when you are moving and will likely lead to a crash. Sometimes when it occurs I can stop moving and the glitch will pass and I can resume playing. It may be harder to to get it to occur if you are standing still. This is all from my own anecdotal experience. It has happened on just about every game I have tested for glide (I have never tried majoras mask). Diddy kong racing, battle tanx are two games it will happen for me everytime.

@quicksilver I got the issue after 22 mins or so. This is going to be very slow progress to debug - I suspect it's some memory leak of sorts as it doesn't trigger for ages. I will test with the latest code on Jessie in case it's related to newer kernels/firmware also
-
@buzz I appreciate you looking into this buzz. Im sure you have your hands full with a lot of different things and waiting around for 22 mins for a bug to show up im sure isnt your idea of fun. In the meantime I have been using save states as a work around to avoid losing game progress.
-
@quicksilver Thanks. I have RetroPie 4.4 ready to be released but this is holding it up. Always bugs :-) I'm aiming for a quick workaround (as quick as possible anyway), so if for example just rolling back the GLideN64 plugin fixes it for now, I will do that (and we can work out the cause and a fix later).
-
@buzz I have done a fair amount of researching the issue (here and on reddit) and I can find similar reports of this happening going all the way back to August 2017. Its hard to know for sure if its the same issue but some of the descriptions are uncannily similar. Im sure most people who encountered this issue just chalked it up crappy N64 emulation on the Pi. Im not a programer but if there is any leg work you need me to do to help you out, just let me know.

Just in-case it helps diagnose it:
I've just fired up some N64 games on fresh Stretch install on Pi3B+ (new 4.3.15 image and then updated this morning), when playing Bomberman 64 on the default settings (mupen64plus-auto) it uses mupen64plus-glide-hires and locked up completely after around 10-15 minutes. I rebooted and forced it to mupen64plus-glide. After 12-13 minutes, I got a visual glitch but it cleared itself within a few seconds and then continued to play fine for over 1 hour.
From a fresh boot, I played WaveRace64 on mupen64plus-auto and this didn't appear to be using glide as it didn't have the fps counter. This played without issue for over 40 minutes.
I did check for logs but it appears the machine crashed out before it could write anything back.
-
Be cool if someone would post what caused the glitch in the first place.
-
@bobberella Nobody knows otherwise it would most likely be solved already ;)
-
Bizarrely, I've just updated from source and loaded Bomberman 64 and played for over an hour on my Pi3B+ (using the stretch version) and there was no sign of the issue. Yet I had it the last 2 times I played it it crashed around the 10-15 minutes mark.

Sorry for my delayed response, I was helping my mate move this weekend and had very little time to mess with my PI or to check the forums.
What I did to replicate this process was to start a game like "aerofighters assault" where the game is in constant motion. This seems to work well with replicating the glitch. Downside, If you just let a normal game run, the graphics may start to "blur" without crashing if the game is sitting idle. I have found that the crash seems to be tied to forcing the game to process new graphical input while the game is in "blur" which happens around the 15 min mark very consistently. If I let the game sit the graphics will just blur but the game will recover because it is not processing anything new graphically. These are just my observations.
My process: I set a timer on my phone for 12 minuets and let the game sit idle until that timer goes off. Once 12 minutes pass, I pick up the controller and play for a couple of minuets until the "blur glitch" starts to happen. This is where I have noticed that if i let it sit, the game will blur and often recover, If I try to interact at all during the blur it will freeze and require a hardboot.

I cannot speak outside of my 4.3 load that I have on my computer, but from a fresh install on a brand new PI motherboard, brand new SD card, I got the same issue to replicate with the stock N64 GLIDE core both before and after updating it from source. I do not have a base version from previous loads to test, but it seems to be an issue both before and after updating from source on 4.3.

@simonster I've had times where the glitch either didn't happen, or I suspect sometimes it comes and goes so quickly and doesn't always cause a crash. Part of the reason why I thought my case was causing the glitch previously.
-
@quicksilver oh well! Thought I was on to something for a moment. I am trying to run top in SSH at the same time to monitor memory/cpu usage and see if it is memory related.
