Yes, looks fine. I played the JP version, but it was pretty similar to the video (which has the US/EU (?) version)

Yes, mine is the EU version

Saturn Bomberman is the game that can be played 10 player, isn't it? Has anyone tried that?

you would most probably be pushing what the lr-yabasanshiro emulator could do on the Raspberry Pi.

i think it's lucky the game is even playable with 1 player on the Pi let alone having 10.

So im having 2 retroarch files for some resaon the game like
Astal
no bios show just run a bit slow but runing well ! with lr-yabuse with this retroach file -
https://pastebin.com/UzTrrtpr
and with the other retrorach file its just stuck show the bios and sega screen then black screen lr-yabasasnshiro .
https://pastebin.com/Kc4chD9w
if anyone maybe got the info more then i do it could help.

If i copy the same retroarch the lr-yabuse wont work... Or just showing the same issue with Yabasanshiro .
tried couple of things , so for know when the lr-yabuse works its using the sec' retroarch.

@shavecat Use the hle bios with Astal.

yabasanshiro -
really lags for me... :
but in
lr-yabause
runs really well !!

Hey guys,

Could somebody point me to a post detailing what the patch for yabasanshiro is meant to be doing?

I think I may have screwed up my installation of lr-yabasanshiro, but I can't be sure until I establish that.

If I am not mistaken, I think it was this: https://github.com/RetroPie/RetroPie-Setup/pull/3132

@Darksavior yep my problems were with the US redump. I tried the EU one and it runs smoothly.

So vulkan is near not sure how we could install vulkan or wait for your guys(Retropie) to release a image, but i wanted to talk about this emulator, i wonder if we will not need this fix version stand alone or lr version, so im hoping we can just use a upstream, but i hope you vulkan will fix this issue also im sure will boost alot of games from running slow.

@BuZz will vulkan run on retropie if i install vulkan or do you guys need to do some work under the hood? Thanks

@notthesame How is vulkan supposed to help with emulators not compatible with it ?

notthesame

I ask cos some devs are saying they got unoffical retropie coming soon with vulkan, just was wondering nothing more.

Is Vulkan supposed to speed up perfomance the way the people wish anyway?
I just read an article about it and the author had the opinion that Vulkan is kind of overhyped.
He mentioned something like "even if Albert Einstein would create the driver it will not speed up slow GPUs to Radeon6000-performance."

I believe it is from a libretro point of view, because opengl in a libretro core adds a lot of overhead (that's something we can't do anything about), unlike vulkan. As a matter of fact, people are often mentioning that redream standalone has better performance than lr-flycast, tbh it's not surprising and would probably be a different story if people compared apples with apples, aka flycast standalone with redream standalone. With vulkan coming on pi4, i believe lr-flycast (which has vulkan support) might outperform redream on pi4.

in theory vulkan is more efficient, which may or may not be perceivable in an RPI context, depending on the current bottlenecks. be mindful that few emulators have vulkan support in the first case. eg, no HLE n64 emulators have it.

He mentioned something like "even if Albert Einstein would create the driver it will not speed up slow GPUs to Radeon6000-performance."

of course. in fact, it could mean slower performance as a vulkan pipeline may have more sophisticated emulation compared to the feature-poor/abandoned gles pipeline, so the pi has more to do.

it’s still exciting for me, for duckstation, beetle-psx, yaba, ppsspp and flycast. eg we won’t have these mysterious precision bugs(?) discussed earlier in this thread (which also seem to manifest in duckstation), in vulkan, hopefully.

yaba

Again, yaba(sanshiro ?) doesn't support vulkan, i believe no saturn emulator does atm.

@dankcushions said in Is Yabasanshiro emulator coming on retropie?:

no HLE n64 emulators

Well, vulkan is low-level by definition, so yeah renderers using it tends to have a LLE approach of emulation, using compute shaders a lot to offload computing to the gpu, not sure it's a lot worse for mupen64plus and parallel-n64 than for the others.

hey everyone, back with more fun stuff and news , or thoses that dont know this.
this helps run yabasanshiro at full speed or atleast a few fps off like 57 or so, i have seen a few games with 45fps this game is VC 1 on the first stage (easy) i think its a bug since theres no target aim.
most of the games i tested ran perfect.
this is for yabasanshiro on rpi4 on retropie only.
im using composite cables, on a old tube tv running at 720x480 i cant run anything higher as this is default for composite and 240 is broken for now.
im not overclocking or anything like that, i do have 20.3.5 mesa on my desktop but you should be fine.

steps

 /opt/retropie/configs/all/backends.cfg

  open backends.cfg and paste  yabasanshiro="x11-c"

```
   save.
```

now launch the a game and see how it runs.

NOTE:
if your screen buttom half glitches, just turn on fps and should fix.
if the game seems to run with a bit of lag just turn off and on the frame skip.

thanks for everyones time if you have questions please let me know, thanks again and enjoy your retropie gaming :)

@notthesame Thank you for this! A friend told me it did work for him and noticeably improved performance when he tested out a couple games. But I can't get that far because when I add the line to the cfg file, my controller no longer works at all once I load a game. Any ideas why that might be, or a potential solution? Thanks either way!
