Description

Game Name?

[Nekketsu Koukou Dodgeball-bu Soccer-Hen + (Other NES games)]

MD5 Hash? (right click the game in the game list, Properties, Verify tab, Verify Integrity button)

[963b9583bd83fcc22e92a8ba1e5bf1d6]

What's the problem? Describe what went wrong.

[On my new computer, when using OpenGL, the Nekketsu game is black screen, only some sprites viewable. I've had issues in other nes games aswell, like Legend of Zelda, with the title screen being jumbled]

What steps will reproduce the problem?

[Boot Nekketsu with OpenGL, aswell as any other NES game]

Is the issue present in the latest development version? For future reference, please also write down the version number of the latest development version.

[5.0-12904]

Is the issue present in the latest stable version?

[Yes/No and version number here]

If the issue isn't present in the latest stable version, which is the first broken version? (You can find the first broken version by bisecting. Windows users can use the tool https://forums.dolphin-emu.org/Thread-green-notice-development-thread-unofficial-dolphin-bisection-tool-for-finding-broken-builds and anyone who is building Dolphin on their own can use git bisect.)

[First broken version number here (if applicable)]

If your issue is a graphical issue, please attach screenshots and record a three frame fifolog of the issue if possible. Screenshots showing what it is supposed to look like from either console or older builds of Dolphin will help too. For more information on how to use the fifoplayer, please check here: https://wiki.dolphin-emu.org/index.php?title=FifoPlayer

[Attach any fifologs if possible, write a description of fifologs and screenshots here to assist people unfamiliar with the game.]

What are your PC specifications? (CPU, GPU, Operating System, more)

[i5-7200 2.50 GHZ, Nvidia GeForce 920MX, Windows]

Is there anything else that can help developers narrow down the issue? (e.g. logs, screenshots,
configuration files, savefiles, savestates)

[Main reason i created issue is that DirectX backends are supposed to be the issue for NES games, especially with nvidia drivers,so OpenGL not working on this computer, but DirectX works perfectly is weird. Changing of ubershaders to synchronous doesn't affect it either]

Have a fifolog of a match in game, which actually displays the sprites, but the background is completely green glitched.

Do you have EFB copies to RAM on? I think certain NES games require it. If somehow the INI isn't loading, that could be the issue.

Isn't an INI issue, as that setting is on by default. Is true though, if efb copies to texture only is on, it gets worse, the green background doesn't appear, only the sprites.

The game renders properly when I run your fifolog, suggesting this is a graphics driver issue.

Yep, I just tested one of my families computers, and OpenGL works on there, so probably is a driver issue which can't be fixed. Thanks for the info.

I'm not as a familiar with the MX line, do you know what generation of NVIDIA that is? Even if we can't fix it, it'd be nice to know what card is having a problem.

Just checked, I've realised something which doesn't change the issue being a driver problem, but changes the graphic card itself. My family has two Lenovo Ideapads 320s, I use one of them, but i assume they were the exact same model, having the same GPU, but actually this model has a different GPU, being Intel HD Graphics 620 from 2016. Sorry about this, I should've specifically checked the computer I'm using.

So this is due to a lack of geometry shader support I've learned.

Dolphin has no fallback for this currently.
