MKDD Tint Issue RPI5

There's also a ticket regarding it here on mesa/v3d, it's something on their radar, although I do notice when I attempt to run dolphin standalone with Vulkan backend it defaults back to OGL anyway, so it's fair to say there's other Vulkan development needed for it to function on the RPI 5, still early days really

I appreciate the sources everyone, but what if I tried downgrading dolphin to version 5.0-6152, where the issue no longer persists? Is that possible with lr-dolphin, since dolphin and dolphin-emu break, and would it be worth it in the first place? Just an idea I had, and I am indeed looking for alternatives.

I also tested with software renderer despite its extremely slow nature, and on standalone dolphin, the issue was fixed. Although, on retropie, the issue persisted and it didn’t slow down at all. Maybe I am not switching the drivers correctly, because I go into the quick menu, switch what I need, and press restart below the resume button. Am I doing anything wrong?

AwesomeKingClem

Uhh, is this thread dead? Do I need to make a new one, or..?

@AwesomeKingClem Not sure what you expect to happen ? You reported a bug in the emulator, same bug was reported to the upstream project. There's no need for a new topic and unless a fix is provided in some way (preferrably by the upstream project), there's no update necessary.

AwesomeKingClem

@mitu Makes sense. I really didn't have much prior experience with forums.

AwesomeKingClem

@mitu Well, do you or anyone else know of any good temporary solutions like gecko codes, downgrading dolphin, or maybe I am not switching drivers correctly?

Re: MKDD Tint Issue RPI5

This was a post I made a month ago, and I would like to know if there are any temporary solutions to this issue. I got the normal Dolphin emulator working rather than just lr-Dolphin. Are there any gecko codes I can try, could I downgrade Dolphin, maybe edit the in-game files, or am I not switching drivers correctly? I do apologize if this counts as bumping, but Mario Kart DD is an amazing GameCube game, and I can't leave it unplayable.

Please don't open another topic, feel free to bump your old topic if you'd like, but there's no need to open a topic with the exact same support issue.

..Anyone?

abj

@AwesomeKingClem I suggest you to ask and in the dolphin discord server : https://discord.com/invite/dolphin-emu

AwesomeKingClem

@abj I can't access Discord.

abj

@AwesomeKingClem No problem, i will report it tomorrow and when i have a answer i will post it here.

@AwesomeKingClem
This is what they tell me in Discord:

reply1: sounds like broken graphics drivers, not much to do about that

reply2: Your graphics drivers lack support for dual source blending. Normally Dolphin can make up for this by using framebuffer fetch, but your graphics drivers seem to lack that too

reply3: use llvmpipe to fix it

AwesomeKingClem

@abj Well, I looked through everything I reported, and my best option may seem to be to use the normal Dolphin emulator (not lr-Dolphin) on Vulkan llvmpipe. I wasn't able to test it yet, so it may be worth a try.

AwesomeKingClem

@abj I tested it, and now it works with the tint completely gone! The only issue I have now is that it runs PAINFULLY slow, even with a 30fps gecko code. Any suggestions, or any other forums with solutions?

abj

@AwesomeKingClem
Sorry, i am out of ideas.

AwesomeKingClem

@abj Meh, I will try to find what I can. I greatly appreciate your assistance! Thank you so much!

AwesomeKingClem

@abj Definitely could've used this earlier :P

@AwesomeKingClem Did that dolphin fork install for you? I get various errors where it's looking for a different version of pangocairo even though libpangocairo-1.0-0 is already installed by default
