@BuZz Just installed, working now. Thank you very much! I did have to to do a fresh checkout of your branch (for anyone else reading).

The patch still won't apply for me, using the latest version of the two files, pulling yabuse 73c67668.

Hi all,

Just wondering if anyone has tried to update their Yabanshiro recently? I was thinking about giving it a go to see if there have been any improvements - I was trying to run ThunderForce V and it doesn't run very well on my Pi.

Then I see there have been some issues with more recent versions and wondered if I should leave my version as it is, and not mess around.

Thanks!
Adam

@adambegood No change. Since Thunderforce 5 runs at around 35fps on my pi4 at 2Ghz/750Mhz, I don't expect to ever be playable.

I'll have a look at the PSX version then...

Sorry for topic spam. I have reset my branch back to how it was in may (probably shouldn't have squashed my changes as had to usegit reflog to roll back).

I force a version from Jul 11th now.

This was before some big merges were made from upstream. Probably improvements for some games but now my test game virtua racer is working again, and due to the issues I mentioned above it's better for now to lock to this version until I have some time to feed some useful reports upstream.

You will need to do a fresh checkout of my branch etc probably.

Sorry for the ignorance but where do I locate your branch?

I've tried to update my Yabanshiro and it isn't working now, presumably because of me having the older patch.

Thanks for the help.

@BuZz Just tried to compile and got the following error message:

/home/pi/RetroPie-Setup/scriptmodules/libretrocores/lr-yabasanshiro/01_shader_hack_rpi4.diff failed to apply.

It seemed from a few posts earlier that the diff failing to apply had been resolved? Is there something I need to change in the original method of installation to get this to work?

Edit: I think I found @BuZz branch and changed the source in lr-yabasanshiro.sh to

gitPullOrClone "$md_build" https://github.com/joolswills/yabause.git yabasanshiro

It looked like it was working and I didn't get the failed to apply diff error, but in the end I got this error message:

Could not successfully build lr-yabasanshiro - Saturn & ST-V emulator - Yabasanshiro port for libretro (/home/pi/RetroPie-Setup/tmp/build/lr-yabasanshiro/yabause/src/libretro/yabasanshiro_libretro.so not found).

Any ideas how to fix?

BuZz · 1 Dec 2020, 23:33

It builds ok here. You probably have an old checkout or didn't reset to my upstream code after I force pushed changes.

Do a clean checkout of my branch in a new location perhaps. I recently rolled back and there are still issues with some games I tested due to GCC optimization of code with undefined behaviour.

Id rather not this become something I'm asked to help with sorry - the current PR builds fine but it's not supported.

BuZz · 1 Dec 2020, 23:43

@firebird_ws6 also don't switch it to my fork. My PR doesn't use my fork of the main code.

Darksavior · 1 Dec 2020, 23:50

@firebird_ws6 I installed it yesterday without issues.

Firebird_WS6 · 2 Dec 2020, 00:03

@Darksavior @buzz I'm still learning with building packages. I'm not sure what needs to change in lr-yabasanshiro.sh to make it use your branch. Currently the default is as follows:

gitPullOrClone "$md_build" https://github.com/libretro/yabause.git yabasanshiro

What would I need to change in this?

BuZz · 2 Dec 2020, 00:34

@firebird_ws6 what do you mean default?

The code is not in RetroPie by default and that line has been changed in my branch some time ago.

Firebird_WS6 · 2 Dec 2020, 00:39

@buzz I meant the files that quicksilver posted earlier in this thread. I'm still learning with Github, I think I found your branch (as opposed to your fork), which it looks like was updated just now. I copied the code into the files on my Pi4 so I'll give it a go at building again. Thanks for your help.

Darksavior · 2 Dec 2020, 00:55

@firebird_ws6 I'm using the scripts from here: https://github.com/joolswills/RetroPie-Setup/tree/lr-yabasanshiro

BuZz · 2 Dec 2020, 01:20

@firebird_ws6 nothing changed in the branch. I just rebased it so it contains recent retropie changes from master branch. You need to checkout my branch and build from there.

You can do this in another location. Maybe Google how to clone a Pull Request on GitHub. I think GitHub provides info on this also on the Pull request.

eg. To grab a copy of this branch.

cd ~
mkdir temp
cd temp
git clone -b lr-yabasanshiro https://github.com/joolswills/RetroPie-Setup.git
cd RetroPie-Setup
sudo ./retropie_packages.sh lr-yabasanshiro

If I update or rebase you can remove and redo or do git fetch origin and git reset --hard origin/lr-yabasanshiro

Firebird_WS6 · 2 Dec 2020, 01:46

@buzz @Darksavior Thanks again, that worked! It's installed and working.

AdamBeGood · 2 Dec 2020, 09:08

@firebird_ws6 Did yours work using Quicksilver's patch? I've entered the code that Buzz gave above:

cd ~
mkdir temp
cd temp
git clone -b lr-yabasanshiro https://github.com/joolswills/RetroPie-Setup.git
cd RetroPie-Setup
sudo ./retropie_packages.sh lr-yabasanshiro

That all seemed to work fine but I am still getting the message that the shader hack has failed to apply when I update lr-yabanshiro, so I wonder if I need to do anything with that patch - or if the above would have updated that also...

Edit: I've tried replacing Quicksilver's Patch file with Buzz's, but the result is the same.

This probably sounds mental but mine is running at 50 FPS consistently on yabasanshiro, I've played a little bit of the game now. This is with the patch not applying. I've found that Radiant Silvergun is totally unplayable now but most games are fine. There is some tiny glitching on ThunderForce but nothing major.

@adambegood Radiant Silvergun runs reasonably well on yabause, as does Guardian Heroes. Both run better on yabause than on yabasanshiro.

Yeah I've found Yabause is fine for Radiant Silvergun, but thank you. Currently between the two emulators, most stuff seems to work even if I don't have Yabasanshiro properly patched. Night into Dreams and Panzer Dragoon 2 seems to run decently also, it is only Radiant which is really banjaxed by not having the patch.
