mupen 64plus texture flickering after update (January 2017)

[Capt_MorganCreek]

Has anyone else expierienced glitchy graphics with standard mupen64plus-glide after it was updated to the latest binary version?

Out of the box with Retropie 4.1 mupen with glide ran SM64 really nice without visible glitches. After updating the emulator games have flickering textures in SM64 and others like e.g. Smash Bros.

Is this a simple config error or is this a bug in the latest version?
Can you downgrade to the 4.1 stock version?

Here's a screenshot of how it looks in Super Mario 64:

And this is my configuration:

Pi model or other hardware: 3B
Power supply used: 3a
RetroPie version used: 4.1
Built from: Pre made SD Image on RetroPie website 5th November 2016
USB devices connected: Keyboard, HuiJia GamePad (N64 usb adapter)
Controller used: N64
Guide used: Official Installation Guide

@Capt_MorganCreek Try updating that specific emulator from source and see if that helps.

I tried updating from source, but I got following error message:

Could not successfully build N64 emulator MUPEN64Plus (GlideN64/Projects/cmake/plugin/release/mupen64plus-video-GlideN64.so not found).

Am I missing something or is there a problem with the source?

[BuZz]

@Capt_MorganCreek could be. I can't tell without a full log. I'll test when I'm next in front of my PC.

Just tested and had same issues with the flickering textures

have you tried "lr-GLupeN64"? lr-GLupeN64 is mupen64plus + GLideN64 + libretro. I have compiled it from the source and seem working fine with the 3 or 4 games I tested.

[Capt_MorganCreek]

@Tasio Yep, tried Glupen, but it's still slower than standalone mupen for most games, especially noticable in the more demanding ones. Since N64 emulation is a bit hit and miss I want all the emulators to work so I can switch them out :)

@BuZz I tried again today and had no luck, but this time I copied over the log file:

Should I try to update the setup script and try again, or would this mess with the settings?

[BuZz]

@Capt_MorganCreek looks like an upstream code issue - I will report it when I have some free time.

[Capt_MorganCreek]

@BuZz Cool, thanks!

Is there a place I can see changelogs of source-updates to emulators, so I know when to update?

[hooperre]

Just curious what resolution you're using. I found the flickering goes away at lower resolutions and am curious if you've found that to be the case as well.

[Capt_MorganCreek]

@hooperre Standard 320x240 resolution. I wouldn't like to go any lower than this, because I'm trying to set the system up as faithful as possible. And it's already pretty low :D

[hooperre]

@Capt_MorganCreek Ah. I only got it at 1280x720.

You would need to check the github / websites of the various projects we include - eg mupen64plus is managed here - https://github.com/mupen64plus

Some code was moved around recently on that project which has broken the arm/neon build - I have submitted a patch to them - https://github.com/mupen64plus/mupen64plus-core/pull/233

There was another error in your log for the GlideN64 plugin - I will look into that too.

Please try building from source after updating retropie-setup script

[Capt_MorganCreek]

@BuZz I'm really impressed how fast you submitted these fixes. I installed the latest version from source without a problem, so thank you!

But...

The flickering is still present and it is even more pronounced in the new version. I tested it with Super Mario 64 in Glide and Glide highres to see if there is a difference, but they behave exactly the same.

Is it possible to return to an older binary or maybe tweak some settings?

To reproduce my problem one can simply install a fresh 4.1 (2016_05_11) image, do an update from source or binary and try SM64 (european version). Overclocking seems to have no effect on this issue.

If it helps pinpoint a workable binary, this texture flickering has been an issue since about one or two weeks before Christmas.

[Capt_MorganCreek]

@mediamogul The 4.1 stock binary is definitely working, but I have no idea what the version is. Playing the games with a fresh install from November 5th works without flickering.

[BuZz]

@Capt_MorganCreek If you think it's a problem with this plugin - https://github.com/gonetz/GLideN64 it might be worth asking them - I will check when I have a chance.

@BuZz

I believe it's already a known issue. Looks like it was reported early last December.
