Is Yabasanshiro emulator coming on retropie?

this sounds to me like a possible "turbocharger" for the Pi0-3

that's hard to say, it would need proper testing, for software-rendered emulators the difference with gl should be marginal (assuming both drivers are of the same quality).

[saccublenda]

Would a Vulkan rpi driver (either for pi3 or pi4) help emulation of 3D games (like psx, n64, dreamcast, etc.)?

[dankcushions]

i am not too optimistic about that rpi 0-3 vulkan driver - since the hardware is not vulkan compliant, it will be missing many features, which is most likely to be a deal breaker for any 3d emulator with vulkan support

the rpi4 vulkan driver may be more worthwhile, but it's WIP.

[barbudreadmon]

@saccublenda Hard to say without proper testing, as mentioned by @dankcushions the driver doesn't seem to be fully compliant.

Also, pcsx-rearmed doesn't have vulkan support (neither gl), you would need beetle-psx-hw for vulkan support (not sure if it's a viable option speed-wise or not, was it re-evaluated on rpi after getting its dynarecs ?)

[saccublenda]

@barbudreadmon I was not referring to the rpi0-3 driver shown in the video, but to the official fully compliant Vulkan driver.

[barbudreadmon]

@saccublenda well, you were mentioning both, and my answer remains the same for the official one (which might be fully compliant, or not)

NVidia Vulkan driver. How'd I miss this?

I think its a good thing. I posted this over a month ago here was no interest in it for some reason. https://retropie.org.uk/forum/topic/24568/is-yabasanshiro-emulator-coming-on-retropie/72?page=4

[acidtech]

Oh it is a good thing. If nothing else its cool how well vkQuake3 plays. That will probably roll over into other games that used the same engine. The question will be how much the lack of some features will hurt it in regards to helping out other games. I'd hope the missing functionality could be patched by software, slower but compatible, which would make this much more usefull(eg drop in instead of requiring modifications to each game to get it working).

hello everybody, can someone please help me build the latest version om my rpi4. i believe that is 3.3.0 but i dont know if the source is already available for building.

Sorry for my english i'm from Brazil. Thanks in advance!!!!!

[notthesame]

@yurioberg no offical release Right Now, please wait for a correct version, these versions(retropies and mine) have crashes, glitches and audio cut offs, so please wait for a better version to come out, we don't have enough information to build offical and other issues, thank you

good news devilmax fixed the bug

https://github.com/devmiyax/yabause/issues/737#issuecomment-665060623

[barbudreadmon]

@myzar it was committed to a git branch dedicated to the pi4 and it uses additional instructions not required by any other gpu, looks more like a workaround than a fix imho

[myzar]

@barbudreadmon

well it's very similar to the workaround discovered here

https://github.com/devmiyax/yabause/commit/22db9a85812cb55333b33115553fd3644c5c1259#diff-74161bd6d86b14189e77e37496f30b8e

it's rounding the values, the branch is not really needed , anyway it works

[BuZz]

@myzar that workaround isn't a proper fix. Which is the point @barbudreadmon is making.

[myzar]

@Buzz i see i see i'm no coder so , i've only noticed that devilmax who's the emu coder used a similar approach

[robertybob]

Just to confirm, is this "workaround"going to be pushed to Retropie (for lack of a better description) or are we awaiting a proper fix?

[ash0904]

@myzar has anyone been able to get bios to work with this new version of yabasanshiro?

[ash0904]

@ash0904 ok so nvm i got it to work with bios.
i used this command
<command>/opt/retropie/emulators/yabause/yabasanshiro -b /home/pi/RetroPie/BIOS/saturn_bios.bin -i "%ROM_RAW%"</command>

[Krakatoa]

@ash0904 What's the reasoning for launching the bios?

[ash0904]

@Krakatoa better capability and performance
