Raspberry Pi 4B 4GB and the Sega Saturn

@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.

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

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.

Zering

@adambegood Night into dreams is a choppy mess for me, panzer dragoon 1 and saga are unplayable. Not sure if I have the patch.

AdamBeGood

@zering Have you got Yabasanshiro?

Zering

@adambegood Yes. It's an impressive emulator.

Weird .. how can it be so different for me? I haven't played much into Nights to be fair, but it seems fine initially at least (40-45 FPS). I've heard there are problems with Panzer 1 and that emulator. Saga seems okay to me, but I've only just started it up really so I can't vouch for it.

Zering

@adambegood Saga is frustrating. The pre rendered cutscenes are perfect. Then you get into the gameplay and it's choppy as hell and the sound is garbled and horrible. Panzer dragoon has graphical glitches that make it unplayable but Zwei is considerably better anyways. I've seen other games with serious graphical issues. Dark saviour has no image or garbled graphics. Enemy zero has perfect cutscenes but no video during gameplay. Deep fear is... I'm not sure how to describe what's going on with Deep fear.

Problem is so far I haven't been able to determine how much the issues I'm seeing are exclusive to my rig or if it's simply due to the experimental nature of the module.

I might give those games a go to see what happens on mine then. I don't think I've heard of any of them.

Edit: Tried Dark Saviour, also v broken on mine.

Considering saturn's VDP1 (the heaviest component to emulate, actually one of the first nvidia gpus, responsible for rendering 3D) is most likely idle when playing CGs, it makes sense.

Zering

@barbudreadmon Of course, I forget how bizarre the Saturn is. ^^

I noticed you have Kronos listed in your signature. How is that going? Any idea if we might see it in RetroPie?

dankcushions

@adambegood it’s already in retropie: https://github.com/RetroPie/RetroPie-Setup/blob/master/scriptmodules/libretrocores/lr-kronos.sh

but only for x86 as the system requirements are to steep for ARM

AdamBeGood

@dankcushions Ah okay, so not one for the Pi4 then. Fair enough! Thank you.

Firebird_WS6

@adambegood Yes it worked for me, not the quicksilver post though. I downloaded the correct .sh to compile it from here: https://github.com/joolswills/RetroPie-Setup/tree/lr-yabasanshiro/scriptmodules/libretrocores

Has anyone had issues with the music cutting out? the games run perfectly fine that i have tested, but the audio tracks keep cutting out for me.

ecto

@manwichman44 Same here. I always assumed that this is a "feature" of the imperfect Saturn emulation. It doesn't happen in all games though, does it? From the top of my head it happens is "The House of the Dead ".
I was just thinking: I have most Saturn games as chd. Maybe it has something to do with that? Some games won't work at all as chd for me.

Manwichman44

@ecto Well so far I'm having issues with Daytona USA and Panzer Dragoon so I'm not sure. It's almost as if the Pi's sd card can't process the music fast enough if that makes any sense.

@firebird_ws6 HI, I've been reading through this thread and I am a bit overwhelmed. I understand that you have given a link to the most up to date and working version of the .sh and patch but I don't know how to use it. As an utter noob I really need some help. Can I simply copy the text from the .sh and the patch, save them with the right names and place them in the appropriate folders (as given above by quicksilver) then choose the option from the experimental modules section of retropie? Also what is the correct bios required? I'd be most grateful for any help with this. I don't think its very complicated but very unfamiliar to me. Thanks.
