Raspberry Pi 4B 4GB and the Sega Saturn

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.

@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.

sergioad

@t1moth I am also wondering how to install it, why it is not on the RetroPie setup?

T1moth

@sergioad I think it is not in the retropie setup because it is unfinished and someone other than the developer has used a patch to get it working. I have now managed to get it to install by copying and pasting the files from here: https://github.com/joolswills/RetroPie-Setup/tree/lr-yabasanshiro/scriptmodules/libretrocores and placing them in the directory /home/pi/RetroPie-Setup/scriptmodules/libretrocores/. The diff file needs to be in a folder called lr-yabasanshiro. Make sure you save them with the correct .sh and .diff extensions. I know this is a clumsy way to do things but I have not really got to grips with git yet and this worked for me.

sergioad

@t1moth I think I will wait, although being able to play SFZ2, NW, MM8, MvS, XvS and other cool 2D games on their ultimate form is enticing

@sergioad alot of reasons its not on the list and
, It is not ready for noob users, issue it has is the graphics get scrambled in random, crashes in few games, not all games run at full speed some 3d do like battle arena toshinden remix from what i have tested it runs great but with vsync off so things are reversed or damaged, this is just some reasons but once you install it runs most games great, with newer updates to mesa some games i had are now broke like die hard arcade and some run better, i did play dracula x the whole game thru out the castle and plays perfect no glitches, only glitch i did see is in the water cave where the fish dudes come out.

Most games do run great and enjoyable but games like virtual cop 1 or 2 run slow, you can play export and it runs faster not sure if it speeds up yo make the game harder or what.

I have tired alot of imports most worked but games like xmen vs street fighter no go crashes and runs super slow.

Id say it is enjoyable and playable on rpi4 with no overclocking

Stay away from Doom has alot of glitches and bugs so no go and besides its not the best port.

But This is mainly why i bought the pi4 for this castlevania on saturn and runs at full speed.

A list of games that run
Dracula x
Batman forever
Battlemonsters
Battle arena tosihden remix
Elevator action 2
Darious gaiden
Golden axe the duel
Daytona usa 45fps to 60 so not bad music does skip
Shinobi
Magic carpet
Marvel super heroes
Mass destruction
Street fighter collection
Street fighter the movie
Street fighter alpha 1 and 2
War craft 2
Mortal kombat trilogy
King of fighters 96
Bomberman
Clock work knight 1 and 2
Contra legacy war
Hercs adventure
Ironman manowar
Legend of oasis
Rampage world tour
Umk3
Raident slivergun
Alien trilogy
Astal
Coton 2
Crypt killer
Three dirty dwarfs
Tomb rider

This mostly why its not on the list but retropie needs a some what work friendly emulator for the community im sure once some things pick it will run most games at full speed in time will tell.

To install try to find a how to or im sure someone can help i could never get it going since i had my own version fixed around the same time buzz and retropie team fix there version.
