Besides, I doubt many beginners will be running dual sdram, and even if they do, they are not really missing much with having only the single ram versions as default. Unless an exclusively dual ram core arrives, 😉 (3DO)
Not sure. It knows if you have an analog board plugged in with the new 9.2 boards
menu core would need modification i think
This is what keeps me from pulling the trigger on a dual ram build upgrade right now. Can't justify dropping the $ on an upgrade to just play a few saturn games better ... especially when I have a real Saturn already hooked up haha.
Hopefully a beefier successor comes out within a couple years and doesn't break the bank.
There’s an option on the single ram core that takes care of most of the performance differences anyways.
Flip that on for the handful of games that need it and you’re good.
It didn't fix Grandia the last time I tried (sorry I know ppl are tired of hearing about that game lol) but yeah, mostly good eh.
Grandia doesn't load half the time on my Pseudo Kai either. might try the tinfoil mod on the cart.
weird about it not loading on the pseudo Kai
the trick is you have to make yourself a hat too
it's been reported before on the kai compat list
apparently better RF shielding might help
lol yeah
I have good TY CD-Rs and have tried various burns, it loads most of the time but will hang on the main menu at times or music will not load properly etc
The last time I tried Grandia on the single core (within the last month), it was slower across the entire intro from the initial FMV until you take control of your character by 4 seconds on normal timings, and 1.8 seconds too fast on fast timings.
I'm waiting the last changes on the SCU from srg320 before redoing some new tests.
Normally some DMA timings will be tightened and that could be better in general.
I have the same problem, the backup cart doesn't work properly, I reported that some weeks ago in this discord, the backup cart set in the main menu is always corrupted when booting the core. this also then affects this save games which are images of backup carts. Thried the set yesterday as well. It looks like the same issue I had when playing sakura wars 2 3 weeks ago.
I have been experiencing the same issue with the backup cart on the latest stable Saturn core. I was trying to retain my ghost data in Sega Rally. If I do a soft reboot back to the Mister menu and immediately go back to the Saturn core, the backup cart seems fine. As soon as I power down the Mister, power it back on, Sega Rally complains the backup cart needs to be formatted.
@ocean wasp @formal barn There's definitely something going on. I now seem able to create a save game cart of the usergames on Dezaemon 2. I was hoping to create several "carts" of various Dezaemon 2 usergames that I enjoy playing. It seems to create a cart, I then save the cart and rename it to the same as the .chd (for example if I want to create a save file of the user game called "DAIOH-XX Demitasse Ver. gamma" from the Dezaemon Save Manager Vol.2" I would then rename the save file to the same as the usergame chd (Dez 2 - DAIOH-XX Demitasse Ver. gamma) which is initially named the same as the save manager chd. While it saves the most recent "cart" and plays fine, it won't then reload the previous carts of usergames I've made. I think I'll leave it alone for the moment.
Yes , tested 🙂 works fine
saroo speed loading breaks some games i thought
saroo breaks games full stop
Ah, ok but something like neogeo cd core
Choose cd speed
neo geo architecture is so streamlined compared to the Saturn.
i don’t think you can really turn up the speed without significantly rewriting the architecture you are emulating; much like the Saroo
iirc, neogeo cd changed the cache size in later hardware revisions, which allowed for "faster" loading, but the drive itself was still a 1x drive.
but yeah i guess it does have a toggle to increase the "read" speed of games, even if it's technically a hack
saroo re-impliments not-an-insignificant portion of the mo-bo
add it to a different core, call it "turbo" lol
I already answered, because it's not possible without breaking other things. Speeding up the CD player doesn't speed up loading times, and the SH-1 is the most limiting with polling time.
The SAROO completely bypasses the CDBlock and reimplements it in its own way, but includes game-by-game hacks with an external database.
That's not viable.
is this the teleporting barry fix?
Yes
Poor Barry
That doesn’t sound good. If I get an ODE I just want to bypass using discs, not modding games.
it's not. people using SAROO are playing a SAROO as much as they're playing a Saturn.
SAROO core wen
saroo fans will never be playing saturn...
Ok so I’m not out of line? It just sounds so wild that you gotta patch games.
MiSTer N64 core says hi (kinda)
i got a Satiator as an ODE of choice, i wanted a MODE but had issue contacting the creator so i got a Satiator instead. works great but idk if it has Saroo's problems or not lol
a lot of homebrew games have issues on SAROO or just don't work at all because the firmware creator hasn't made bespoke patches for them (he only cares about the retail library)
Ok you’re right 🤣
bubububububu that’s different!!!!!!!!11110
I mean it’s a slightly different thing
it does not
the Satiator doesn't emulate the CD block, it just tricks the Saturn into thinking it's reading from a disc when it's actually reading from an SD card. it accurately reproduces original CD-ROM seek times so as not to break some games that expect a certain length of CD loading time to set themselves up.
Ok that’s what I would want
i hear good things about fenrir and it's relatively inexpensive compared to other ODEs so you might want one of those
yep Fenrir is good too
Unless your name is Týr, then it’s awful.
AMIRITE @strong osprey @twin canyon ?????
no one knows norse mythology
Anyway, I appreciate all efforts to get consoles working on mister
but I keep my saturn with MODE for a reason
mister is just very convenient, but if im planning on playing through a game, start to finish, i'll just as soon break out the console
I'm the opposite really. Id have to setup my Saturn downstairs with my ossc.
i do like the saroo's faster load times, as it helps a lot in games like sonic 3D blast, but as discussed above this is achieved through bypassing the CD block and using all kinds of weird hacks and patches
it's funny to think that playing saturn games on mister is probably more accurate than playing them on real hardware via the saroo
You can enable the normal CD loading speed globally though for the Saroo.
Yes!
I was just reading the discussion and at the same time the image with the updates appeared.
srg320 is not sorg, just to clear up an all too common mistake
He works elsewhere during the days.
I cannot say much more.
DCC and Open Bus tests are green now, the core is recognized as a VA2 mainboard model (SG RAM for the main memory).
SCSP is okay, like always -all green-, no regression found.
I'm waiting the other tests to finish, some are rather long and extensive.
SCU tests are green except for a DIVU extreme case (some 64-bit division results). Mednafen and Ymir are using the same algorithm but srg320 have a doubt about it.
The current VDP2 test is all green, but testing only very partial parts of the chip (celeriyacon is working on it since some times).
Normally, all regressions from last time should be fixed, but some tests are needed.
I'll let you test it for yourself, because I don't have time and I need a break for a few more days, but I wanted to follow this release closely.
Why this release in particular?
Some important changes with the latest internal tests from celeriyacon.
On the SCU, on the VDP2 and the DCC + open bus.
I also like to help Ymir sometimes and see their progress on their end.
But some healthy competition is also 'fun'. 😉
Who will be the first to pass that test, or that other test.
srg320 seems to be someone who enjoys challenges when I talk to him.
thanks for the clarification
Changes that make those components pass tests that the core didn’t previously?
Absolutely.
Nice
Just some magical touch here and there.
3DO core coming along nicely I see 😏
In a way, every bit of progress on the Saturn is progress on the 3DO
The real progress is the Saturn core we made along the way
celeriyacon provided some more complex VDP2 tests a moment ago.
srg320 will look at them tomorrow.
was there any time in the past where the 'backup cart' saved/loaded?
ok, there was
unstable for December works correctly
current release/unstable the backup cart is broken
fixed it; PR sent
I was just finishing to create the issue ticket.
So, I'm adding the PR to the issue log, thanks Zakk.
This seek delay fixes brought back the slight animation/audio desync in Albert Odyssey's intro on my setup. The sound appears to be slightly faster than the animation. The current stable mister main doesn't have this issue.
please try this file
Will give it a try and report back.
This gave the same result. The sound is just slightly faster.
ok one sec
We tried everything with srg320 these last weeks on some parts of the core.
Some tests will definitively fail with the SCU DSP DMA on Single RAM systems, even after adding the timings option.
They require absolute accuracy and precision on RAM-H, that can't be achieved on that configuration.
The dual RAM system could pass, but at the limits.
For the end user, this won't change anything, simply for the future preservation and documentation of the Saturn system.
No change in terms of animation/sound sync. Sound is still slightly faster.
sorry for so many files and thanks for testing 🙂
You're welcome. 🙂
Should I reopen the issue over at github or wait for further developments?
you can reopen 🙂 please let me know if there is a change with the last file
Oops. Missed it. Will give it a go now.
No change. Sound is still faster.
Robby, don't pin those! 😏
Instead, peg them
lol, tagging me in the saturn channel like i'm supposed to care about the lamest system ever created oolololol lamer
mario? no? only a blue dumb hedgehog
Not even, you get Bug and you like it
will B4 get a saturn port
Depends on if we hit that Kickstarter reward tier
The Bug! fandom is dying.
Like if you're a true bugger.
what is dead can never die
the crow is a real feel good game on all levels
opens with a father and son being shot and dumped into the lake
Didn’t someone die playing that game?
probably
Me every time I boot up the Saturn core
Gif deleted!!!!!
Ok maybe that’s too far lol
Zet-sensei should be given the title Liaison to the Gods.
@ripe valley @warped saddle I was able to do a quick test with "Saturn_unstable_20250718_111e11.rbf" on my lunch break and I am happy to report that the backup cart saving/loading is working great so far. Sega Rally retains my ghost data after powering down the Mister. As I would expect, the save file increases from 64kb to 1,088kb now that the backup cart is writing properly. I will do further testing with some other games tonight. I will also test the dual ram build later. Thank you for pushing this fix.
Tested it myself, worked fine so far. Only some dezaemon things worked not as intended as it stuck with devil engine on the cart regardless of switching the saves. But maybe I'm too stupid will test some more
Just a follow up. “Saturn_DualSDRAM_unstable_20250718_111e11.rbf” is also playing nice with the backup ram cart.
It didn't meet timings though, I'm told. I also couldn't get a build that met timings
Single SDRAM wins again! 🏆
Why does single ram win?
I think it met timings
but I honestly don't know how to check
kuba told me and I trust kuba implicitly
Single ram has better timings than dual ram?
the build met timing which means, right now, it is theoretically more stable
the dual ram build may have weird bugs under certain circumstances....or it may be fine
You met timing
ur mom tho
Damn. Lost again.
I was just testing the backup ram save/load function. No long term play. Just quick loading of games, powering off/on the mister, etc. Making sure the backup cart save file wasn’t getting screwy. Good to know about the timings though.
Nah, I am a noob 🙂 so I wanted someone to verify me, I failed with good timing ( dualsdram)
Another bad build maybe?
As of yesterday I have not encountered any problems with the latest unstable dualsdram core, let's not panic 
It is perfectly fine to panic in such a situation.
Image if worse comes to worst and there will be 3do development
I am convinced that the development of 3DO is going well
Knowing srg320, this is exactly how it is
3DO is low priority, even now.
I left some more homework to srg320 during last night.
Oh well 🤷
Due Monday: Battletoads
srg320 can't work anymore on it.
Due Monday: fix every quirks of the VDP2.
I assume he doesn’t have the pcb anymore?
Ever? Or just priority-wise doesn’t make sense for now?
EDIT : Chances are slim, but no zero. Some sentences between us were open to interpretation, so I'm doing that edit.
The exact term is : suspended.
For the most part, he lost almost everything and/or cannot access it anymore.
||I'm not doing politics, but you know the reason why quite well.||
Ohhh
is this the battletoads arcade game we're talking about here
That sucks
It was a victim of escaping Ukraine
So he’d have to start from scratch? Bleh
Too bad that game is good times
I could see starting over being depressing on something like that
EDIT : Some sentences between us were open to interpretation, so I'm doing that edit.
He thought about it, read the code on MAME, and decided to keep the core as is at the moment.
Is it only hardware access or did he not push the code due to understandable reasons?
His code for Battletoads is all on GitHub isn't it?
Yes.
Hardware access and costs.
(I need to go for today.)
Oh so lost the pcb. That is an expensive one
Last time someone sold it near me they were asking $800 😦
Hey do we know when SNAC for the digital pad may be available for Saturn? Thanks!!
doesn't that already exist?
i most certainly have been using a snac adapter with a saturn controller
Yeah MA sells Saturn snac for his products
Not sure about other options if you don’t want to live in the SNAX / reflex adapt ecosystem
Saturn SNAC is available and I believe most if not all Saturn controllers work with the Saturn core. At least I can confirm the virtual on twin stick, mission stick, racing wheel, 3D pad; and lightgun all work.
...all except train controllers.
lol that’s the one system I don’t have a Densha de go controller for
He didn't escape; he just isn't where he used to be.
krikzz survived a bombing a day or so ago
Last I heard, krikzz was in Spain. Didn't know he went back. srg320 never left, he just moved.
I'm not sure he went back. he was posting about a bombing that happened in his hometown; the pictures were not his
I didn't want to say more about his situation, yes he moved to a safer place, but he must have left things behind to the occupied zone.
So, that's considered as lost (even from his words when I asked one day).
That's unfortunate, but at least he's safe.
Zet, as a tangent since you are able to communicate with him- any chance he might release his logic analyzer work? He uses a de10 nano, right?
He uses the de10-nano yeah.
Presumably his gear could be replaced? If there are things he is after I am sure people in the community would be able to help get them to him.
Most of the gear was replaced already.
Oh, what is the blocker?
The arcade board, I presume
Yeah if that’s it they rarely come up (checked ebay and AP real quick and nothing to even buy) and people want $800+
I don’t think most collectors will loan stuff too willingly either even though it’s just rotting on a shelf with 300 other unplayed pcbs, it goes against their mental illness to do so 😜
If makes me sad thinking of all the retro hardware that has no doubt been lost in Ukraine in the last 3 years
Was ordering some retro graphic cards right before 2022 and best deals were from Ukraine. One order I made just as things were starting (on ebay) I let them keep the money because they couldn't send it out
Not trying to turn chat into politics chat but yea it all sucks
Hey team, is the STV core available from update_all or do I have to do any extra work right now to get it? I ask b/c I haven't updated my MiSTer in forever, and I decided to just run updated all, it's now at 2.3.1, but I don't see STV or SEGA STV anywhere in my folders. I should note, I don't have any SS games saved on my SD card, but I do see the core.
It's an arcade core, you would see MRAs for the STV games in your Arcade folder. Not a core you load and choose a game from.
Thanks, so update_all doesn't grab the MRAs?
I guess, what I'm saying is I ran UA and don't see an STV folder or Sega STV folder in my arcade section.
I believe it just throws them in with all the other MRAs in the root of the _Arcade folder, and does not seperate them. I don't know if Arcade Organizer supports STV yet to filter them out like that.
What''s the recommended games for STV to check out?
Let's see... there's:
Your Mom Forever
Your Mom Boomerang
Your Die Hard Mom
Your Mom Zone
Your Mom: The Duel
Groove On Your Mom
Your Mom Action
Your Radiant Mom
Your Mom Sliders (or Your Steep Slope Mom in the US)
I would start with those.
Batman and your mom is my favourite
Radiant Silvergun, Die Hard Arcade, Soukyugurentai , Cotton2/Boomerang
Shienryu, Groove on Fight
Radiant Silver Mom
burning moms
All these Awbacon alt accounts! 
Elan doree
Is there a fix for the vertical oriented STV games so that they're in the right orientation? I could totally be missing something, but I went to play Shienryu, and it's not rotated. I didn't see an option to rotate anywhere.
there is not, unfortunately
bummer, oh well. thanks!
Dont forget Saturn BombYourMom
and Three Dirty Moms
(yes I know these arent STV)
Hey, I watched that video too!
Who is in charge of Arcade Organizer so I can put a bug in their ear about getting this organized?
The AO uses information from the Arcade Database to organize the MRAs. Please report any miscategorization you see in your _Organized folder there if it is due to incorrect metadata.
Its probably this that needs updating https://github.com/MiSTer-devel/ArcadeDatabase_MiSTer/blob/main/ArcadeDatabase_CSV/ArcadeDatabase.csv
I’m going to update arcade organizer soon
Vacation time now
That is why I decided to get a Satiator
I liked that it is more true to being like a CD
Also, I want to play games in the optical disc drive and seemed (to me) the best option for both CD plus ODE
I also got the MODE and that's been solid, but I thought I'd like just one more device for no good reason.... really... lol
Congo the Movie: The Lost City of Zinj, a Saturn-exclusive FPS, is much maligned partially because of how difficult it is. But it might be worth revisiting now that Bo Bayles has discovered a swath of previously unknown cheat codes! He reveals them in his latest Under the Microscope:
@warped saddle Are you and SRG still working out MRA and alternatives? I wasn't sure if everything was still just in _Arcade, or if you have started doing some weeding
there's no real alternatives for ST-V, like only a handful and I put them in the alternatives repo
What do you think about Dynamite Deka going to _alternatives? If you're good with it, I'll add it to today's massacre
seems fine. I don't really care that much. I think there's another situation there with that Tecmo soccer game
still can't get saturn to save games
i lost track of the latest core github
which unstable build is
MiSTer_unstable_20250723_07fb7c ?
if you're using backup cart you need latest unstable Saturn core, as the backup cart was broken previously for maybe a month-ish.
just grabbed the newest ones
the newest release has cut the debug option to turn on/off sprite layers
i use that feature myself for screenshots so i’ll copy an old core for reference
i am mainly worried about OSD save issues .. have lost so many playthroughs because it would save
mainly Lunar SSS
which memory is the best to choose at the moment? .. have only been using DRAM 4M
can't wait to get a Hi-Saturn.. finally get to use my SAROO Sp Edition
also picking up a VCD/SVCD card
i don't think the saroo works with the vcd card does it
not that you'd be missing much
it works with the SAROO .. at least the version I have.. also supports 8MB Memory according to the new firmware
already confirmed with J&T Studio.. even confirmed that it works with a 1.5TB SD Card
creator of the saroo said this so idk if it would work with any games that make use of it
I guess J&T doesn't know their product.. their website is basic with no explanation
Still planning to buy a VCD card though... Am thinking of buying some games on the side regardless if needed or not
They are also getting harder to find
Wow .. I feel stupid over this whole saving ordeal... Kept mistaking the healing statue for a save point
Explains why the OSD wouldn't save
games with vcd support should still work if you play from original/burned discs i assume
saroo is still a great product imo. it's hack-y but a good, cheap solution to play saturn games with much faster load speeds
would love to see how the 8M memory translates on the mister though
How does VCD card work with Saroo if they both occupy that slot
Oh, I'm thinking of Satiator
I got the whole VCD thing out of my system using burned games and a real VCD card
Better FMV quality for sure in a handful of games
Vatlva !
Gungriffon
Really, Lunar is the one
I also watched martial arts VCDs on a CRT, pretty sweet
I'll have you know I own both the SEGA card and the JVC one
Sorry for the lack of update, urgent family matters and traveling to another country for the next days/weeks.
You didn't miss much so don't worry.
srg320 is working on the core on his side and I follow some time or when a question appears.
I just checked out some Ymir issue reports that I might be interested in when I get back, they have a tester who only uses ultra obscure games.
Obscure, even for me.
Doing some comparisons and checking that everything's alright.
Bye, for now.
Ymir best Saturn emulator on PC?
It hasn't reached Beetle Saturn (Mednafen) levels of high compatibility yet, but it's slowly getting there.
And people are also slowly catching on to the emulator, considering it's a new kid on the block, and the people are already loving it.
In 1 or 2 year(s).
The most easy part is done.
Now, it will bé much more difficult.
Where are we at now with the Saturn core? Is there much left to be fixed? I feel like have been a foot from the finnish line for months now (always the way with projects I know)
The whole VDPs need a refactor, the SMPC too.
I sometimes wonder if Saturn homebrew devs use the core for testing their games and software.
QA and whatnot.
Not those I know of.
Either they don't see FPGA as viable, or missing some knowledge on the FPGA environments.
Most of the system work, but we were not accurate enough for being future-proof.
Damn, that sounds like a lot of work
That's the current step being done right now.
As an aside, can someone provide a one liner for Saturn to be added to here:
https://github.com/MiSTer-devel/Wiki_MiSTer/wiki/Cores-supporting-RTC
It doesn’t support RTC, does it? I thought you could only update the system clock
I thought it was added a couple of months ago?
Does the clock not take time from RTC?
bruh
I didn’t think so. I thought it was just temporarily saveable and didn’t get reset on an (in core) reset
this has been in the core properly working for over a year
So at least now you can play nights at Christmas or whatever it was called
Thanks. I was wrong
I was going off my memory of the commit in Dec where everyone thought it was implemented but it turned out it wasn’t
If someone wants to give me a line I can add it to that wiki page tomorrow, am out now (or someone else can go update it)
Saturn sales data from right before the Dreamcast launched
SAYS A LOT
But the top 10 has good games and Super Robot Wars
Is this the place to talk about the ST-V core too or is that for a different channel?
Nah, this is the place 🙂
I was trying out a few ST-V games and could not get DaeJeon! SanJeon SuJeon to work, it just says cartridge error and to press the service button
Service Mode shows no cartridges installed, I checled the rom and bios and both match the CRC, even tried copying them to mame and that ran them fine
I think you need the unstable STV for that one
I take that back, I know you need the unstable STV for that one
if you grab the unstable, rename it to the date on the current stable, delete the current stable from /_Arcade/_cores, and then copy the unstable in there, it should work and update all won't grab the stable core
Oh, so it's going to be fixed in a future update?
yeah exactly. it needed a new piece of hardware
I see, thanks.
Look at you not linking to my story 😛
(Or to the SX thread I got it from)
Oh I’m sorry! I got it from another Discord.
cheating on us 😕
What issues should I be looking for when playing Dark Savior via CHD? I’m about 25% through the game and haven’t noticed anything broken.
Well you should first check if the game is good, if it isn’t then Dark Savior is working correctly.
oh that's one of those multi index games. it's just going to be wrong audio in some cases
if at any point you've had a thought like 'this game sure uses this music a lot' that's probably why
I have the disc but haven’t played it in years. Nothing has stood out yet.
The flex you should truly be in awe of.
This is the thread where that sales chart comes from: https://segaxtreme.net/threads/dreamcast-game-sales-in-japan-almost-full-list.25805/
The Database used for this list is from the Sega Dreamcast Magazine as well as its successor Magazine Dorimaga published by Softbank Publishing in Japan.
The Start Point used to be Sega Dreamcast Magazine Issue 8/2001 published on the 16 of March 2001. Starting from Page 61 there is a full List...
It has lots of other numbers in there, too
Yep! Lotta good stuff in there
Top tier jank
Me owning this is 100% Gamefan’s fault. They were overly kind to it in their review.
It's fun as hell with friends
Found 2 obscure games not working on the current core.
Left 2 issue tickets to srg320 already.
Otherwise, the core is pretty solid now, even against the latest versions of Mednafen, Ymir, SSF and yabaSanshiro/Kronos.
I tested the current core against all their respective opened issue tickets/known issues as of today.
is there a list of games that require fast timings to match original hardware
no not really, most here can name a few heavy hitters that perform terribly without it.
but no one who insists on singleSDram has sat down to play side by side with original hardware and catalogue their findings
that's unfortunate
You can't always detect when a game needs them.
Sometimes it is just a scene on a whole J-RPG game.
Or a specific action, like on Decathlete.
not for me!
DUAL SDRAM 4 LYFE
I need to check once more Zero4 Champ DooZy-J Type-R.
I left a note on the compatibility list that it used to work on a core from early 2025.
And I will probably need someone else to test it too, just to be sure that I don't miss something here.
single ram gang will not take this slander lightly
Just cheked, black screen on Zero 4 Champ too, latest unstable main and core.
The last time I checked the game was on 2025-01-11.
And left is as Playable back then.
I need to go for today.
Terra Story blacks screens for me as well.
I hope the issues lie on the SH2.
Is Radiant Silvergun still showing slowdown while using the seek weapon?
It did on original hardware didn't it?
MiSTer wins again? 
Probably. I don't recall any difference between the Saturn hardware playing it vs MiSTer but there were some reports earlier that someone noticed it had slowdown.
Might not be identical slowdown on both - but I'm sure I remember getting killed playing on real Saturn due to frame drop/slowdown. I don't have the hardware any more
I remember people saying they prefer the JP ST-V version because it removes the slowdown, compared to the real Saturn version
Ooh! Neat
Shouldn’t this be pinned?
It seems like a decent enough amount of discs, especially with the Saturn core being the only one to support index 2+, that it’d be worth a pin.
Or am I just being stupid?
Or, wait, maybe this and the attachment should be turned into one message and then moved to #help?
I think some of that is pinned in here?
Not at all, it’s a great thing to have pinned so thank you for thinking of that.
I have it linked as part of the Important Info pin which also lists a bunch of other things users should be aware of - #1046941029296779344 message
The Saturn is the only core currently to support indexes beyond 1, so the Saturn is prolly the only core that needs this.
Do you know what indices are used for? So weird that only the Saturn uses it.
it's so you can index into different parts of an audio track
although funny enough you can't jump directly to an index easily, so I kinda wonder why they did that
I mean... it kind of should be a blanket statement not to use CHD on this core because of all the games that have issues, and the potential for others
the only one anyone ever noticed was Chase HQ anyways. not exactly a list of popular software there
I could probably come up with a way to fix it but I was kinda hoping mame would
The list is small and obscure enough for me to not really care 🤷♂️
I don’t blame anyone for caring but I haven’t noticed any issues and even if there were I wouldn’t notice them anyways lol
It’s those two and Dark Saviour for the “big games” right?
And Princess whatever
Let me rephrase, games I have heard about lol
And the WWF games, I guess
somehow i've heard of timegal
But you can play In Your House on the PSX core
But it’s not a big list, that’s for sure
SPACE JAM nooooOooo
I have that on the PSX core 😅
the only one I’d care about is Dark Savior, I don’t mean the other games aren’t cool, just either play them on different systems or I’m not interested in them
its probably worth a few lines in the readme or something, its enough games to come up from time to time
yah
Didn’t somebody do a good readme for the core a while back?
Yep: #1046941029296779344 message
I love the SURGAH SURTURN
Robby getting in touch with his inner Bubbles...
Some more tests and reports to the compatibility list today (60% of the whole worldwide library achieved).
The good news - no other regression found and all the games tested today are working correctly so far.
Core is done! Pls close channel and peeps move to the 3DO channel now 
The core is not done at all in terms of accuracy and peripherals.
Overruled!
Did ash's fix for lightgun on the 480i menu screens of scud get merged?
i’m sure it wasn’t
It needs p2 set to light gun also, otherwise the menu loops
why must saturn heads always opress us innocent 3do likers
the 3do oppression will continue until moral improves
Not sure if that's been tested on real hw, surely it works with just the gun you play with in p1
In fact, I was away for 11 days, so srg320 could have work on the 3DO.
We haven't talked each other since then.
Damn I hope not
@ripe valley is the hero we need
...and the one we deserve!
Is there a way to officially add japanese ST-V games in Arcade Organizer? I added the MRAs myself but it keeps erasing when updating. I only play Radiant Silvergun in Japanese (nobody plays the crappy USA version).
on the OSD you can choose the alternative bios (japanese one)
and save the settings to make it start every time on this settings
BIOS select is grayed and stuck on Default. I can't change it. Tried in games and in the unstable cores too.
And I have the lastest cores too.
weird ... i have to check again tonight
If you have lastest unstable core I don't know if the latests mra were retreived also
I don't use update all on my side
You need to use the unstable stv core. Also, I know zakk has a PR to add Japanese versions to /_alternatives, but there is a bug in the verification script that needs to be fixed
What peripherals are missing? I thought everything was sorted out with snac.
When using the OSD is there a "JP BIOS" directory at the top inside of the ST-V directory? The games should be in there if you use update_all.
Arcade > ST-V > JP BIOS
Analog triggers on 3D pad, the Twin Stick, MIDI, Keyboard + FDD Operator, Video Card, NetLink.
Some of them won't be supported or maybe really later.
He means supported or replicated through USB so SNAC isn’t required.
And I don't know the future plans of srg320.
Good to know, thank you both!
My vision should be to finish as possible the accuracy on some chips, even with the current state of the core.
We have acquired some recent knowledge on the SCU, SMPC and VDPx chips these 2 last months, thanks to celeriyacon.
Lack of Analog triggers in the Saturn core is a MiSTer main issue. I am under the impression that adding support for an additional two axis for analog triggers is quite a lot of work and until the Saturn core there wasn’t a reason to implement it. Even then, it’s debatable on the amount of effort being “worth it” for such a small handful of games that support it.
Not my opinion of course. But it’s the gist I got when I asked around.
sgr320 added the RAX sound board for... one game.
I won't be surprised if he wants to do other parts too on the Saturn.
it was so sad
Well hopefully someone is willing to work on input.cpp to add analog trigger support. There are a few arcade games that could benefit from it too.
We need to support the Photo CD Operating System.
Otherwise, moondandy will throw a tantrum.
and negcon emulation on psx core too!
Damn I keep forgetting that. Maybe that puts it over the edge for Sorg?
its kinda hard to describe why its needed for that
it seems pretty fine already but you can't accelerate and brake at the same time
Right because two buttons are analog
yeah and 1 trigger bizarrely
and that has support in like, maybe a hundred games? practically every racer on psx would benefit
has anyone contacted Sorg about analog triggers/buttons?
practically every time there's a complaint, nobody even bothered to ask 😄
That’s what I do!
well do it harder
lack of analog trigger support in main entirely prevents playing Sega Rally's later revisions with analog steering and gas/brake since the controls can't be remapped. one of the main features of the definitive version of the best game on the console doesn't work over USB. it's extremely worth it to get that working.
I think so too but I don’t know how to add support 😥
this is in response to "Even then, it’s debatable on the amount of effort being “worth it”"
strong, strong disagree
it's a strange situation. sorg said he'd think about implementation in a github issue a very long time ago. it will be pretty disappointing if this (analog triggers over USB) is just not in the cards for MiSTer at all for whatever reason. playing Sega Rally with analog controls on a modern controller is really fun and feels quite different than digital
given the state of the Saturn core, its worthwhile implementing
Yes but you aren’t the one who has to do the work and neither am I.
You are only mentioning one game that would use it and even then it’s fully functional with SNAC.
So to the person who needs to implement it, there already exists a solution and it’s called SNAC. See what I mean?
The challenge is putting together enough of a convincing argument for the person who has to do the work, unpaid work mind you.
Beggars can’t be choosers
Just gotta be good debaters lol
master debaters you might say
when someone in a position of authority says "Even then, it’s debatable on the amount of effort being “worth it”, the most important thing i can do is say "actually it's entirely worth it". that's not begging or anything inappropriate. robby can be a bit defensive about the capabilities of Mister and downplay missing functionality. it's important for people who recognize the utility of those features to push back and say, no those actually are important and should not be downplayed. SNAC is not really aligned with the original intent of MiSTer, which was to be able to use modern displays and controllers, etc. i don't think Sorg himself thinks SNAC makes USB analog trigger support superfluous or he likely wouldn't have even bothered to claim to be thinking about implementation
I’ve got no authority, I’m just a dancing monkey they keep on board because I make memes lol
Yeah good point, my intention wasn’t to read as “maybe it’s not worth it” but rather it’s something we gotta convince someone it’s worth doing.
And I’m trying!
lol
i appreciate your efforts
I appreciate your passion, thank you. I’ll be better about how I express myself. Apologies.
you're all good. i just want to offer my personal view because playing Sega Rally with analog is literally the one thing i want to do with the Saturn core but cannot. i don't really care for SNAC, my Saturn controllers are fine but part of the joy of MiSTer is using modern equipment that's not normally natively compatible with old consoles
I’ve never been a fan of “just buy more stuff” as an answer. I get why it’s said but ultimately you just want to provide support when possible and not require people to keep investing money.
Maybe I’m wrong, I just like that idealized approach.
But yeah I literally play Sega Rally at least once whenever I boot up the Saturn core. Holy shit it’s so good.
the absolute best!!!
i just don't want to have to hang onto my saturn just for analog sega rally or have to get a snac setup just for that one game
it's important to me! i will do anything i can to help get it across the finish line. for now that seems limited to just voicing that it's still very important to me! 🙂
(part of it for me is the Saturn 3D pad has relatively springy triggers - with analog trigger support i could use a pad with short-throw which is way better for my carpal tunnel)
For sega rally, a racing wheel works pretty good. Even being limited to digital gas and brake.
I bought the console as at the time the core was missing the Snac arcade racer wheel, or light gun and other peripherals, even though it was in the cores menu but I'm not sure what the core does now, although I do have a Snac lead.
Robby the personality hire
What kind of resources do we need for the Movie Cards to be supported? "Larger" FPGA? Better ARM?
Not being snarky or jokey but I think the biggest barrier is finding someone interested in working on it. I am unsure about the technical hurdles but Slamy is addressing something somewhat similar with the DVC addon for the CD-I core.
But a lot of software for the CD-i requires that addon so the “need” is more for that core.
someone working on it for this core is probably not going to happen, the fpga is basically full at this point
There is also only one game that requires the video card, which is dubious since it's just another version of Lunar: Silver Star Story.
The SEGA Saturn already has a version that doesn't require it.
Netlink support would be nice, and that is the type of thing srg has been happy to hand over to the arm side in the past.
But what if I want to watch VCDs through Saturn on my Mister? The Saturn controller has play, pause, stop, fast forward, and rewind buttons for a reason.
Basically if it can’t play VCDs what’s even the point of having a ‘Saturn’ core?
Listening to the startup sound?
I heard the Saturn has games
I think you're confusing it with the Playstation
Definitely not confusing it with the Jaguar or 3DO though 
You haven’t lived until you’ve played Nanatsu no Hikan
Oh damn it’s a horror adventure game. Ok I’m interested!
Yeah see! List redeemed!
So if Sega does what Nintendon't, and Nintendo has games... what exactly does Sega do? 🤔
Has better games!

You mean I fell for Nintendo hype?!
I've always thought Nintendo was overrated myself. I'm sure I'll be roasted over hot burning coals for saying that.
Even today, they just don't really do much for me. I don't own a Switch 2 and don't care if I ever own one. I barely touch my Switch. The SNES was definitely fantastic, I think it's the best console they ever made but nothing else ever did anything for me
Half my personality is based on liking Nintendo so I feel like you’re directly attacking me!!!!
Hey it's great for those who absolutely love it. I totally get it and respect. I love the Mario games and Metroid!
MiSTer turned me into an unapologetic Sega fan lol
I don’t know what that means but I’m trying to say I like Sega very much now
😂
I've hit a point in my life where I just love video games..some consoles are better than others but that doesn't mean even the lesser ones don't have something to offer
And besides I love an underdog. I had a 3DO when I was 12 and I absolutely loved that thing.
Keio Flying Squadron 2 is one of those Saturn games that Europe got while North America didn't. That meant no English 60hz version of the game existed — until KoolFiller's new patch! Get the details in DoubleDime's story:
https://www.segasaturnshiro.com/2025/07/31/keio-flying-squadron-2s-ntsc-version-now-in-english/
SWOAH SUPER COOL
saturn shill
Hah! I think we are well covered with CDi for Photo CDs, so I don't think anyone will be disappointed if the core doesn't also support Photo CDs. Would be good if it got keyboard support though, that could be ported over to Mega Drive core as well. I read that people have rewired Saturn keyboard port so it can work on Mega Drive and there are homebrew that support it
Finally, I can play it in English in NTSC mode. When I played it 6 years ago, it seemed to me quite interesting
The analog triggers were only on the 3D controller right? The one that game bundled with NiGHTS? I would say that's worth it for that game, though, did it even make use of them as analog? I recall them only being for doing tricks. Weird that it would be bundled and not make use of the triggers too.
Oh nice! Wasn't that a game that even used Japanese characters for it's numbers? Though I had no idea there was already an English PAL version
the pal version is entirely in english but the dub is pretty terrible
the option to play with english graphics and japanese voices is absolutely welcome
Does the dub version of this patch add the PAL dub to the Japanese version? Or was it redubbed?
This translation patch takes almost all the PAL-exclusive English text and voices and applies them to the NTSC Japanese version.
Included in the post is another patch that only translates the text. KoolFiller says, “This version keeps the original Japanese voiceovers, movies, SFX, and the Japanese title screen.”
I like the dub in a so bad it's good way, which to be fair fits with the general campiness.
There’s no subtitles to the videos so heads up if you decide to use the Japanese voices.
Just copied it into place, will play later
Are there any major differences between the titan/saturn versions of Guardian Heroes?
Probably the biggest difference is that it's not on the ST-V
i assume they meant guardian force lol
The Shanghai port on there is great btw
On where ST-V?
Yup
Pretty sure its on saturn too
This teeny-tiny article needs some work. You can help us by expanding it.
Shanghai: Triple-Threat, known as Shanghai: Banri no Choujou (上海 万里の長城) in Japan, is an entry in Activision's Shanghai series of games. It was released for the Sega Saturn in 1995, then later ported to Sega Titan Video arcade hardware.
The Saturn core have slowed down quite a bit these last days, as srg320 seems really busy elsewhere (no 3DO), and I need to be with my family at the moment.
Please be patient until our mutual returns.
no expectations, duder. and if you feel anything other than that, let me reiterate: no expectations 🙂
I expect no expecatations.
We've gotten more than we expected. Thank you for all of the hard work
Speaking of 3DO and Saturn, in regards to games that don't convert to CHD well without issues due to having multiple Indexes. Is it specifically if they have an Index 2 and later, or if they have more than 2 indexes?
I was doing a scan for any of my CD games that have "index 2" or "index 02" in their cue files, and I only had four results, three Saturn games which are on that list, and Disk 2 of a 3DO game
Thing is, it only had two indexes, Index 1 and Index 2. Wasn't uncommon for games even on PSX to have two indexes, but generally they were listed as Index 0 and Index 1
So it having more than two indexes that causes the problem? Or having an Index past 1 that causes the problem even if you only have two indexes total?
anything past 1
@celest lake im on a de10-nano not misterpi
if that changes things
also dual ram if that also changes things
dual ram changes things
board flavor does not
it is not present on the dual ram build of the core
just single
manual download
They are coming up with a solution for dual ram builds
but right now it's all manual
unless you use the WIP database
then it will come down with update all
err unstable updater I mean
add these to the bottom of your downloader.ini if you want all the testing cores
db_url = https://raw.githubusercontent.com/MiSTer-unstable-nightlies/Unstable_Folder_MiSTer/main/db_unstable_nightlies_folder.json
[ajgowans/wip]
db_url = https://raw.githubusercontent.com/ajgowans/wip/db/db.json.zip
It will put them in the /_Unstable folder, so they won't muck up your normal folders
if only the de10 could handle a core with a dual sdram toggle
So then disk 2 of the 3DO version of that game (Braindead 13 if that helps) also can't be compressed to CHD even though it only has two indexes because it lists them as 1 and 2 instead of 0 and 1?
it can be compressed but the info about track 2+ is lost. without knowing if the system/game actually uses those indices I can't say if that matters or not
played a little of grandia 1 on saturn core to see what the game was like, i can dig it
probably play it after i finish 2
I am going to assume it does, since it's a FMV game and the index 2 has a specific time listed
Ok then, guess that's also a 3DO game that if that core even comes out I can't compress to CHD
that time is also like 4 seconds before the end of the track, so who knows
Oh it’ll 100% come out and I’m guessing about a year after it’ll be close to perfect
Is it an infrastructure problem? (As in, the MiSTer framework doesn’t have support for checking for the second stick)
Or is it just a MiSTer thing.
I think it is more fundamental, so a core can only be one or the other, it can't be both single and dual ram
Dyatona USA Championship Circuit Edition used the triggers to have analog acceleration and brakes. The gears were set on Y B Z C ( gears 1 through 4, respectively), so one could change the gears like it was possible on the arcade cabinet.
Could have sworn I have seen cores that have a (greyed out because I only have one) option to use one or two sticks of ram right in the settings
the psx core has a setting to use ddr3 or the 2nd sdram for audio, but that's not the same
I'm resuming some Saturn research and already sent it to srg320 earlier today.
StrikerX3 also found some flaws in the Saturn test suite and I shared those findings with srg320 as well.
srg320 is alive and kicking.
We discussed about some recent discoveries on my side and shared some thoughts about the flaws on the Saturn tests suite.
The flaws won't affect the core and srg320 already knew about them.
And for some discoveries they will be added to a next version of the core.
wonderful
I try to give an update, we are working on it, less regularly but we are still doing it.
"I'm Batman"
are srg320’s efforts all core accuracy focused or has he been able to address any user-side feature requests
Most of my work with him is about accuracy and bug/issues resolutions.
When it comes to user requests, he's usually surprised us, especially me.
So I can't comment because I don't have any information at all.
it is great that he is safe with the situation !
Sure the situation is worse ...
srg320 asked for some more tests to be added on the VDPx tests suite today.
He is working intensively on the chips' accuracy and timings.
Ironing out the last quirks on them.
In some cases [on the VDP2, for context], FPGA is simpler and more accurate than software emulation.
Maybe this will also improve the adaptive dithering blending? Right now it's pretty inconsistent between games.
does the vdp1 mesh option even do anything currently?
ah i see, thanks for the clarification
i tried it in sonic jam's sonic world and didn't see any change, so i guess that explains it
The ultimate mesh transparency hack
The audio and animation are back in sync during the intro of albert odyssey with this build.
Hi all,
Am I the only one who's experiencing issues with Decathlete on the latest (20250718) ST-V dualram core? If I keep the attract mode running in a loop, I get untextured models during some cycles, as it was when the core was in active development. The most affected is 100-meter dash, but sometimes, this is reproducible with other disciplines as well. Usually, the first or second attract mode cycle is affected. If you can't reproduce, try restarting the game.
I can also reproduce this on the single-RAM core, although with different disciplines. In my case, it was the long jump.
My setup includes Mister Pi 2nd batch (Dual SDRAM) and HDMI output. vsync_adjust for ST-V is set to 0.
Is this with the stable version of the core? Or the unstable?
The unstable version of the core. These specific builds: https://github.com/MiSTer-unstable-nightlies/Saturn_MiSTer/releases/download/unstable-builds/ST-V_unstable_20250718_111e11.rbf
Cool. I’ll take a look later today
I can't reproduce it since at least 2 hours.
Let's see if TheJesusFish will have a better "luck".
I can make a screenshot if needed to show what I mean.
it sounds like it's pretty obvious, yeah?
Should be, but you never know for sure :).
I wonder if @celest lake TheJesusFish can turn bins into cues
A screenshot should be better, so I can be really sure what we need to search. @tribal needle
You're too fast, @marble laurel
😂
I was going to test new things on the SH2, but srg320 released the update just before.
The temporality 😅
Here's what I mean.
On the next attract mode cycle, the models are textured properly.
fear is the mind killer
That's normal behavior, it's the mascots of the game.
I see. Thanks!
The game cycles between the players characters and the mascots.
I guess I don't get to stare at track and field sports for an hour
now my whole morning is freed up
happy saturnsday
I will finish my current job workflow, test the new findings on the SH2, report to srg320 and do an update of the 32x core later today.
An announcement here.
The core has passed all currently known tests (DCC, SCU, SCSP, SMPC, VDP2 & SH2).
From one of the least well-documented consoles a few years ago, we now have one of the most precise cores in the MiSTer ecosystem.
The work is not completely finished as we have to check other things on VDP1 and some future tests of celeriyacon.
srg320 asked me and celeriyacon to test and verify some really obscure system quirks.
Sorry that’s me, I wear my gimp suit out on the track when practicing for the big event.
I need to check the 32x compilation and upload it within the next minutes.
Keeps me motivated you know?
oops, didn’t mean to interrupt your awesome news
Ok pins updated! Make sure to grab the latest main too.
Bad day for 3DO fans
A Saturnday can never be a bad day! Even as a 3DO fan!
Weren’t there some 32x games that didn’t work before? Do those work now? I want to say some Sonic game but that’s pretty old info. I don’t care about 32x so I’ve never once tried the core or paid much attention 😉
Just Star Wars Arcade freezes on a specific stage.
There hasnt been an official release for 32x for a year, maybe it should receive one after so many changes have been made since.
It’s funny they did those ports of sega model 1 stuff for 32xeven though it’s weaker than Saturn which also couldn’t do sega model 1 stuff anywhere near 1:1
I guess not when you consider there’s a “port” of vf2 for Genesis
as long as the gameplay transfers 🤷♂️
Regarding VF1 and VR ports, gameplay was spot on, surprising really. Fact is, at that time, I couldnt tell it was a downgrade graphically, blamed it on a 14 inch crt and composite.
They are great ports
We were huge VF dorks and spent countless quarters on it in the arcade and of course bought Saturn on release for it. I have to say despite being a less than stellar port and we knew that being so familiar with the arcade yet I and my friends sunk a stupid amount of time into it because like you said they nailed the feel even if they didn’t nail the visuals
Having a 32x core that I never touch is the height of luxury
It's luxurious
This is me
I could play an accurate representation of 32x at any time..but I won’t affected rich villain laughter
wait when did the new cores drop
can’t tell if this is specifically ST-V
or both
Well, Crusader is specifically Saturn related
Namely?
Are we at the point where we should get a new 32x build released with the fixes on the shared parts from Saturn and updated .sys? Is there anything that is working in what is live currently that isn't in the zet sensei dev builds?
Some SCU DSP overflows for me & study the HRES register latch position for celeriyacon.
Parts that aren't inside the tests at the moment.
It's just for extreme accuracy -and being future-proof-.
Right now:
- Knuckles Chaotix crashes during the attract loop randomly on the stable. This is fixed on the unstable
- Star Wars works on the stable, crashes on level 2 of the unstable.
So, comparatively, the stable is still probably the better option? Unless Zet disagrees
We need to fix Star Wars before doing a stable release.
We could skip the issue on Chaotix on the current stable, but not the one for Star Wars on unstable.
I'd like some tests on Mortal Kombat II, I'm not up to the task and I don't know exactly what I need to check, but others seem to check it regularly.
My own agenda was also to help on the core before the release of the SuperStation One.
Being able to load discs with a very reliable and accurate core.
The stars are aligned, better than we have thought.
Sadly, we can't fix everything with the single RAM build, limitation of the RAM bandwith.
So, the fast timings option will stay for now.
Do you know if SRG is planning another stable? Or is it going to be a twice a year thing
I need to talk with him tomorrow.
Leave that on the 32x section instead of here, please. Concerning Star Wars arcade (it was for Wark before he removed his message).
So, we could trace better our testing.
yeah sorry, if it wasn't clear, I was talking about saturn 🙂
I was replying to wark about Star Wars, he removed it from here and added to the 32x section.
I'll check with him tomorrow, but for now, I'm quickly testing a few games.
ahh gotcha
maybe one day we will have a Sega Saturn inspired MiSter built around dual SDRAM spec
probably just as easy to fully fork the work at that point
When I saw the core presented at a previous Tokyo Game Show with a Saturn case, and knowing the people behind it, I thought, "Don't even try it, you..."
They won't contribute to the development of the core by enriching themselves through the work of others.
I must prefer to see Taki succeeding on the SS1 and probably see a Saturn variant one day from him.
potentially much cheaper, none of the analog circuitry would be required just a small secondary bank of ram
Unless they wanted to do some switch between analog and digital mode
or really customize it and make it capable of SDRAM and dual output
Rock is Sponge!!!
Is the core as accurate as Polymega yet?
Far better than the PolyMega, as it is based about an older version of Mednafen and we surpass it on every front.
Shienryu Saturn is broken.
The sprite layer is missing.
Is it a VDP1 or VDP2 issue?
We haven't touched on the VDP1.
So, VDP2.
Same for Panzer Dragoon Saga.
I saw the regression too on the character name select screen.
Maybe a bad build?
No, we touched the HV counters, so something broke with them.
I need to check with srg320 tomorrow.
Ah, probably old code messing with the recent changes.
No more 3DO.
Looks like enabling fast ram timing does some screwy things to the BIOS load screen? An entire layer completely disappears ie. on the JP splash the copyright text goes, on the EU screen the Saturn logo and copyright text disappears. Resumes boot once disabling fast timing on single SDRAM.
I will check the build tomorrow, I just saw that too.
Sorry, I was joking
no, polymega veury goos
Wait... so PolyMega is not better than MiSTer?
...cancels order
it even has mega in the name
Exactly!
can't trust anyone anymore
I thought Robby was supposed to be looking out for us...
I have a pile of Raspberry Pis all because of him.
Turns out, they really weren't better for games.
I don't need 15 Pi-holes...
are you sure? surely no ads will get through
The current update_all downloaded core version date should be the same as the manual one in the pins, right? (Sorry, I’ve been terrible busy and absent)
Give Google time, they’ll find a way to get even more on YouTube
No, the one in update_all is currently outdated. Please download the latest unstable builds if you want the most recent changes.
Apologies if this is covered off and I've missed it, playing the SotN ultimate 1.1 on the single ram core and it seems super choppy. Tried 2 different MiSTer devices and same on both. Youtube footage looks much smoother than what I'm getting (I know its a terrible port but i don't think that's the issue)
choppy how? like skipping frames or
Apologies for the awful video, but its like Alucard is in slow motion
have you tried the retail disc without patches?
I'm pretty busy and redoing the compilation of the core at the same time.
I will check within during the next hour.
Yes, original unpatched Akumajou Dracula X is the same
Annoyingly my Saturn is not accessible at the moment to compare with real hardware so it might just be me misremembering
this is definitely slower than usual
i remember it running fine on previous versions of the core though, so perhaps there's been a regression (assuming you're on the latest unstable)
I beat it on real hardware a while ago (original unpatched) and don't recall it being that slow but also couldn't be certain I wasn't confusing it with the PS1 version either!
yeah, the ps1 version is definitely smoother, but the saturn version should be faster than your video at least lol
Delete your core config and try again with default settings
I am using latest unstable build, issue seems worse in save rooms so that's one way to reproduce
//media/fat/configs/
Stable core has no issue (25.06.13)
Are you fat shaming his configs?
Robby no longer loves fat babies, only phat babies
//media/phat/configs/
The single core is at the extreme limits in terms of Fitter operations (99% of the FPGA is necessary).
Tha could cause some troubles and timings issues.
Does dual have lower usage?
2% less.
I wrote a new story about the Saturn core's recent progress:
https://www.segasaturnshiro.com/2025/08/08/saturn-mister-core-now-passes-every-test/
Lemme know if I messed anything up, heh
You forgot to write that FPGA gaming is CYCLE ACCURATE and a PERFECT recreation of the hardware. Also you didn’t mention that if you don’t play Saturn on a MiSTer you might as well BE DEAD,
Maybe not that last one
you better watch it buddy or I'll quote you on that
Same for me, latest dualsdram
No emulation.
Thanks for confirming, glad to know its not me going crazy!
I mean, that could still be possible but that’s not something srg320 can fix.
You make an excellent point sir
At the moment, I don't know why Kuba-J have the slowdowns on the Dual RAM, but not me on my system.
I can look
The current concern we have comes from side effects encountered after changes to match tests, parts not yet added, or new discoveries about timings between different ICs.
celeriyacon's technical tests are essential for development, but there are still elements not taken into account at the moment or adjustments to be made without disturbing the current result on said tests.
Good to go.
DSP overflows are fine on the current unstable core (I don't have to do anything on this and srg320 was already correct).
We have to wait for some changes and additions to the next Saturn internal tests suite.
StrikerX3 (from Ymir) also has access to it; we are working as close as possible to the situation.
I can confirm the single ram version of the unstable has a problem with SOTN
trying dual ram
I tried on both the previous unstable main and the current
dual ram has layering issues with the loading screen
it is slightly faster but still slow compared to the stable
checking a different mister
this is the one that I hold in my bare hand while rubbing my feet on shag carpeting
Thanks, I'm adding a note on the issue ticket.
We will need several days.
Poor little DE-10 Nano, we are asking too much now
Confirmed on De10, MisterPi, and QMTech
but here is the fun bit: only seems to happy in the save room?
save and loading rooms
Save room and the CD transistion rooms (corridors).
ya
The sprites are also flickering when you move, like the candles.
ahh yep, I see that
So, I opened 2 distinct tickets.
I'm tempted to search the previous core code, and only add the SH2 module and the change on the SMPC.
But I've been working too hard today and need a rest.
Thanks for investigating all 👍
Do you know if srg320 plans to include a save state option ?
we know he’s never announced plans to do so
likely there isn't room
and the whole core is at 97/99% thing
yeah there's no way
save it for replay2 or whatever
he doesn't really write cores with save states in mind
maybe snes style
lol thanks for playing along with my dumb joke
Do any emulators other than SSF even have that feature?
Pffft, big deal! That guy who originally wrote Nesticle is making a transistor-accurate emulator! Let's see MiSTer compete with that! 
It can’t 🥺
Ymir have it since weeks.
Don't think I ever tried that one, will check it out.
StrikerX3 is working very hard on it.
Keep in mind that the emulator is only about 6 months old in total.
Your dumb jokes make up around 95% of the posts within this server 😂
Burn!
I hope we don't get out of server space for dumb jokes though.
I'd like to think if the Saturn core is only 99% full there's space in the remaining 1% capacity to fit in a knock-knock joke
Knock knock
Who's there?
Robby
Robby who?
Exactly...
The good news : the recent issues are related to the VDP2 changes, after my current internal tests today. The other changes on the SMPC, SCU and SH2 are correct.
The bad news : I can't revert the changes on the single RAM core, as the code no longer fits within the limits of the FPGA in terms of the number of cells required.
So, srg320 will need another trick when fixing the code.

Saturn core is officially dual SDRAM only now!!!! 
The single RAM core will always be just a little bit less accurate.
For the end user, nothing will change.
Random but I really enjoy Biohazard 1 on the Saturn more than I do on the PSX.
I like all the quirks that came with the Saturn port. Like how they dealt with transparency
Thanks @ripe valley, glad you worked it out. Been thinking of going dual ram as there's a few other games that need a tweak in single ram or is that not a thing anymore?
I really do not see any downside to running dual ram if your using hdmi with your mister.
He’s right though, I’m on here way too much.
It looks fantastic imo. Higher polygonal models too, right?
Especially with how cheap ram is now. (Paid under £20 for mine shipped from Taki)
I will only use my Mister via hdmi.
I think? It's quite an impressive port and it looks amazing
I have two, one DE10 and a QMTech but both have analog boards, although QMTech stays pretty much HDMI only so i can probably work something out on that.
Never properly played Resi on Saturn, I have it but my muscle memory is so used to the PlayStation controller for those classic Resi games its hard to adjust
Guys, this is srg320 you’re talking about. He can just write some code to increase the number of LEs in the DE10
Il be honest. I really like playing Resident Evil on the Saturn controller (well M30)
It feels so nice
I wonder if tank controls will come back in fashion with the switch 2. Imagine playing RE1 with controls like Drag x Drive
My M30 arrived yesterday, those classic fighting games just don't feel right with anything without six face buttons
For SOTN/Akumajou Dracula X + Shienryu, this is a regression and should be fixable with some work.
For games like Fighting Vipers and other 3D games with a similar physics engine, there's an option called "Fast Timings."
On Grandia, we tried everything, but the game requires very precise access on RAM-H for some moments.
The "Fast Timings" option will resolve most issues, except for three textures in the game after a few quick tests.
I am a tank control scheme enjoyer
I wonder if you can twiddle the ram overclock bits directly from a core
Yeah it's a cracking controller. I use that with an SN30 (for SNES connected via a Timville 4daptor), ultimate 2c and the 8bitdo PCE controller
My controller situation is well out of hand so made a conscious decision for Mister to stick to an M30 for classic Sega and anything else a DualSense... Sadly as NES is my favourite console I'll probably have to concede and keep a wired controller for that hanging about. I must have hundreds of controllers all over the house and the adaptors to match
Ah. I just ended up buying 8bitdo controllers. For nes (and other consoles that use a 2 button layout) il use the PCE controller.
celeriyacon added and said 3 weeks ago about a test for the VDP2 called "H/V CNT, TVSTAT, IST Timing" that it will be brutal.
We probably won't be able to successfully implement it for a long time (for srg320 and StrikerX3).
The test is successful with the latest unstable version (and all others).
So I expect the latest regressions and required LEs won't be a problem for some time.
We really are so fortunate to have such talented and dedicated people doing all this work
Now if only they’d realise that they’re squandering their time by not working on the Virtual Boy instead 
I went abroad for a semester back in the day and when I returned everyone had switched from Genesis SFII over to PSX SF Alpha. The downgrade in controllers was shocking to me
Give me the JP Saturn controller any ole day
I tried the N30 and it's 99% there but it feels slightly off, i think i just spent so much time with the OG controller that nothing else works
That is a great controller, for wired i built a Daemonbite and use the OG Saturn pad but just needed the M30 for the convenience of wireless in the living room. Got an 8 month old learning very quickly how to get around and wires feel like an accident waiting to happen!
I toadally understand. I use M30 wireless on the MiSTers. The USB Genesis is for my PCs typically, but would be great for MiSTer also
I have a large # of Saturn controllers, but the cords get so kinked and are annoying
Plus various adapters, RetroPad32, other stuff
Got a couple of those 8 button ones recently. Absolutely recommend.
RetroPad32, attach any controller to any console
mostly
Also supports PCs via USB
I looked into those but they seem super difficult to find
i havent heard that name in forever lol
wish these were still a thing
are they not?
Early days of MiSTer
I feel the same with the saturn port, it has a charm to it that I don’t quite feel as much on the psx port
if they are, i can't find them for sale anyway
Sexy detail
I think that was Antonio Villena's very first kit
Looks like he's been busy
Not sure about those rough edges tho?
Anybody got a lightgun recommendation for modern screens? Seen loads of conflicting info
describe your goals/setup
Supposedly GunCon 3 is good, but I could not get the alignment
Always offset from the sights
I don't wanna waggle a reticle around
IIRC there are DIY sensors now for GC3, which saves money
yeah, if you want a “good enough” solution. grab a wiimote and sensor bar, or guncon3 and rely on a reticule to keep accuracy like a wii game
if you want to go from good to great, gun4ir
Is it possible to play Point Blank etc. on PSX using GC3? Don't the PB games require extreme responsiveness?
If anything will push me to make space for a CRT, it’s light gun games
I feel like CRT is the only actual answer if we're chasing authenticity, sadly
I have a behemoth HD CRT for PS2
IIRC that display causes issues with certain games
I have a CRT and Guncon 2 and seeing all pros/cons for LCD solutions sticking to CRT is probably the solution
I can def recommend the retroshooters reapers on a modern display. It has replaced my crt and snac guns.
How hard would it REALLY be to start a CRT production line again
With TESLA money and resources or something
I say when you’ve got gun4IR set up properly, it beats the original experience for accuracy. it beats crt’s with sheer screen real estate Virtua Cop on a 65” OLED is sinfully good
Sounds great to me
OLED, Tink 4K, gun4IR? That would cover everything but ... 3D (Famicom glasses, etc)
Friggin CRTs
yeah its fun
No, I’ve stopped producing it and my other stuff too for good-ish
that's very sad to hear 
I’m still able to make one here and there for some specific use cases: for example, I made one for one user here so they could test it on the Switch 2. And it worked! 😃
What a huge accomplishment
Srg320 is a beast
I just talked about it live on the SHIRO! Show actually
Saturn is probably one of the most difficult systems to emulate accurately, or so I heard
But srg just kept going
100% comitted to quality
He's in it for the long game
The Saturn MiSTer core will go down in history as one of the greatest gaming preservation accomplishments.
And these efforts will carry over to the next project where new HW should allow for more freedom
Just add a script in update_all to download more LEs
Though, damn, I didn't think the Saturn would use up that much of the FPGA. The N64 and PSX cores don't use close to 99% right? I guess this means no possibity of MPEG or Model 2 support on MiSTer then 🙁
SRG is a founding member. This ain’t his first rodeo
Found one with a good d-pad? Most modern dual-analog controllers seem to have a poor one that constnatly registers diagonals when you keep switching from left to right, especially on NES. Was trying to find a good dual-analog controller with analog triggers and hall effect sticks which has a d-pad that dosen't suck 🙁
I know this is a joke, but I am curious if the DE-10 can support 3D modes over HDMI. I do have a 3DTV, would be neat to play Virtual Boy on a big screen in 3D
don’t be sad for bonuses not implemented inaccurately, be happy for the core experience being so accurate.
wanting more done poorly is the path to RPi
Oh yeah, and there was that recent hack that allowed Virtual Boy games to run in full color
True, we don't need the MiSter to become Nesticle2 or ZSNES2
That fan grille in the left eye... should have also just done that for both eyes and added a connecting line to go for that full 80s shutter glasses effect
the perfect glasses for scanline fans
This has become one of my favorites: https://www.8bitdo.com/ultimate-bluetooth-controller/
Bluetooth®. Compatible for Switch
I think thats exactly the one I already have, just the wired version of it
As well as a slightly upgraded version of that one
Not really came across any issues with my 2c. However I know some people do not like the d pad on it
Yeah, it's hard to pin down. Not sure what to do to find a good one outside of just buying several controllers and testing each one. 🙁
I noticed that it's easy to tell with Contra on NES, mashing left and right on an NES controller works fine, but on many modern controllers my character will randomly aim up or down when I do that
The Dual RAM version is fixed on my side.
The Single RAM will need some more time.
Dual ram redeemed
I left a TEST version to Kuba-J and TheJesusFish.
If they don't find anything out of place, the build will be shared, otherwise it will be returning to the drawing board once more.
he became famous when he showed up out of nowhere with a fully working snes core. circa 2018?
mister would not be the same without him. sega cd, pc engine cd, then saturn, hit after hit core
They're perfect. Exactly the white point I've been looking for.
Thank you, by the way. 🙂
Totally unrelated but... Thank you for RetroNAS!
Oh yeah... that too. 😏
I believe it’s a story of legend that he developed most of the SNES core (if not all of it?) without even having one. All done from documentation or something like that
Someone who’s been around longer will know the story though
I almost said the same thing 😂
…and it was good
he developed all of it 100% by himself without an actual snes, yes. He based himself on Byuu/Near's Bsnes
since Byuu was focused on preservation and accuracy, he had the ultimate source of documentation to build a snes emulator
not to mention Byuu had every chip decapped, including the on-cart chips like SFX
Indeed
the power of srg320 to recombine the atoms of the universe with the power of his mind into a replica of your beloved childhood gaming thingy (he’s never even seen it before)
“I could go the the shop to buy a SNES oooooor I could just create one myself”
i love how he kept calling zelda "that fairy boy game"
Yeah that’s my favorite story too. Built an entire SNES at the bare copper level and never heard of Zelda.
he's not wrong lol
well wait, there wasn't a fairy that followed him in the SNES version
now all we need is to have Sorg implement analog triggers so I dont have to use my saturn 3d pad all the time
like I get the aprehension but analogue triggers makes a simulated negcon controller viable
If he can add rumble to snes
I can assume analog triggers is feasable
it's not apprehension, it's just a shitload of work and he's the one that has to do it
and he didn't add rumble to the SNES core, it was someone else who forked it
fair enough
he needs to add rotation to the DV infoframe first. everyone else is in line behind that
also they are unrelated. rumble was easy because it was already there due to psx core
(your welcome)
is the negcon 6 axes or 4?
4 i think? twist, 1,2 and L (1 and 2 are the tall buttons)
I feel like 95% of people's needs would be met by just allowing some way for per-core axes mapping of the existing 4 axes
