Is Yabasanshiro emulator coming on retropie?
-
All set... Going to use these four (4) settings that consider RLE vs. real BIOS and original res vs. native res:
yabasanshiro-sdl = "/opt/retropie/emulators/yabasanshiro/yabasanshiro-sdl -r 3 -i %ROM%" yabasanshiro-sdl-native-res = "/opt/retropie/emulators/yabasanshiro/yabasanshiro-sdl -r 0 -i %ROM%" yabasanshiro-sdl-saturn_bios = "/opt/retropie/emulators/yabasanshiro/yabasanshiro-sdl -b /home/pi/RetroPie/BIOS/saturn_bios.bin -r 3 -i %ROM%" yabasanshiro-sdl-saturn_bios-native-res = "/opt/retropie/emulators/yabasanshiro/yabasanshiro-sdl -b /home/pi/RetroPie/BIOS/saturn_bios.bin -r 0 -i %ROM%" -
Been playing around with the YabasueEmulate function. It's pretty much the core of the emulator. Anyone else here trying to improve performance?
After moving some of the execution order around some it seems it doesn't matter if SH2Exec(MSH2 executes before or after the SSH2. If that is the case why aren't these threaded to run concurrently?
I dug a little into them and I don't see any big hold ups. I suspect in some cases there may be a syncing issue but in those cases there is no work around anyway so who cares?
I did some rough profiling and while running the intro of Sega Rally(used it for consistency) I saw about 10 to 20ms of processing time for the master and the slave(so 20 to 40ms total time per frame combined).
I also checked the RPi cpu usage. Core 4 is pegged at 100% and cores 1 thru 3 average around 50% or less(using lowest graphics settings).
Does anyone know any reason this absolutely cant be done? I'm planning on starting work on it unless I get a real good answer as to why it wont.

@acidtech i think you should raise an issue at the github - devyimax is the only active developer: https://github.com/devmiyax/yabause/

fwiw, we tried this in the kronos emulator not long ago, on desktop there was no performance benefits, it was actually slower because of all the syncing.

@myzar Sorry for being dim, but how do you quit the Retro-Arena build without a keyboard?
-
@mechafatnick I'm awake, so jumping in.
The select button on the gamepad should be auto-mapped to the Yabasanshiro menu. Then you can select Quit. -
NVidia Vulkan driver. How'd I miss this?

@roslof duh! thank you. Didnt think to check the controller

Wow, just read this, thx for giving this information @barbudreadmon!
Well, i am no professional, but 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).
-
Would a Vulkan rpi driver (either for pi3 or pi4) help emulation of 3D games (like psx, n64, dreamcast, etc.)?
-
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.
-
@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 ?)
-
@barbudreadmon I was not referring to the rpi0-3 driver shown in the video, but to the official fully compliant Vulkan driver.
-
@saccublenda well, you were mentioning both, and my answer remains the same for the official one (which might be fully compliant, or not)

https://www.tomshardware.com/news/nvidia-engineer-vulkan-driver-raspberry-pi-quake-iii-100-fpsI 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

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!!!!!

@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
