Is Yabasanshiro emulator coming on retropie?

steeeb

The best thing to do is probably to down a fresh install using the official image on the website.

Do nothing but install the scriptmodule, add Saturn roms and Saturn BIOS.

Confirm it works.

Then copy over your retroarch, confirm it works, copy over stuff one by one and confirm it works.

Probably the quickest way of seeing what is breaking it. If everything gets back set up how you want and it still works then it's something horky borky with your packages or drivers or something you changed and forgot or isn't important to you. It's probably the only way of finding the issue without much back and forth - and you seem capable enough to quickly to do that.

Just don't change too much in one go in case something breaks it and then you'll need plenty of back and forth and remembering what you did to undo stuff and that is usually pretty time consuming when 6 hours later you finally remember that change you forgot to note down - speaking from experience .

Good luck - and post your findings.

@steeeb you're reading my mind!

My last post on this, unless I find the root cause.

First of all thank you, all of you, who provided help. I absolutely love the support around here.

I executed exactly what @steeeb suggested and, as expected, with a clean system, Yabasanshiro boots all of my test ROMs (Saturn CDs) without issue. I then copied over all of my configs, /boot/config.txt and it still works perfectly.

So after 48-hours of doing nothing but troubleshooting, I'm now convinced that my issue (on my original SD card) is related to a low-level problem. Either something became corrupted or maybe a I have a bad driver that I've been unable to clean/flush and rebuild. A shame since everything else worked perfectly, but Yabasanshiro was my original Pi build's Achilles heel. Begs the question though: What is unique about Yabasanshiro? What does it call that other emulators currently don't?

I'm now likely to rebuild from scratch (ugh) since Saturn development, no matter how early, is important to me.

Again, thank you guys. Will report back only if I have anything that can help others.

Cheers!

@roslof for what it's worth, some games I've tried that work are Die Hard Arcade, Sega Rally and Virtua Racing.

Do you have sound in die hard arcade? The main menu has sound (albeit very quiet), but once I get it game i have no sound it seems.

pjft

@quicksilver I have no music other than cutscenes, but I have sound effects. The audio is fairly low on the emulator, though - maybe that's it?

If you're keen on playing Die Hard Arcade without sound, AdvMame is your best choice - the performance is much better than the Saturn version with the exception that it doesn't have sound.

Anyone have any idea what (12S) and (15S) might mean for saturn roms? for example: Virtua Racing (USA) (15S).zip vs Virtua Racing (USA) (12S).zip ?

I find quite a few saturn roms have these though the numbers vary. Otherwise the roms are the same.

@quicksilver quote from a redump team member hanging at the kronos discord :

That's the final stamp on the ring code that you could found on the backside of a disc.
Generally, for classyfing the revision and/or the number of the print/master glass used for a specific game.

quicksilver

@barbudreadmon so the difference should be largely negligible?

Dinierto

@quicksilver that's my understanding. Dreamcast dumps have the same thing

For anyone testing this emulator, if you have a game that won't boot properly it's worth trying with the hle bios option turned on. I was able to get virtual fighter 2 booted this way otherwise I just got a black screen.

Radiant Silvergun has severe glitches making it unplayable. Sometimes they go away.
Oc'd to 1900Mhz.

I have been doing some testing and I noticed that the glitches only seem to happen during the intro before the first level. The glitches don't continue into the game as long as you don't try skipping the opening cut scene sequence. If you skip the cut scene then everything glitches out during gameplay and becomes unplayable.

Yabasanshiro got a noticeable update to 3.2 but the repo hasn't been updated?

Yes, i already mentioned it, devmiyax is providing the sources a long time (weeks/months) after distributing binaries, which imho is against GPL license and the reason i basically withdrew from that core. When the sources will be available, maybe i'll sync, maybe i won't, tbh updating that core is pretty much like throwing dices, with lots of regressions every time, and i don't see that fact changing with its HLE approach, not that i think there is much choice when you want to emulate the crazyness of saturn on toasters.

Do you have the radiant silvergun issues with the sh2 interpreter ? If you do then there are still issues between yabasanshiro and pi4 mesa drivers, if not then there is probably something wrong with the dynarec.

Darksavior

@barbudreadmon I understand your decision. That's unfortunate. Glad I asked him on his youtube page then. I expect no response.

No change when using the sh2 interpreter. It must be the mesa drivers then.

@Darksavior There is no breach of license unless he refuses to give the source when its requested. All you need to do is request it.

I asked a few times, but every time he kept delaying it for weeks, so i just stopped caring about this core, it's provided as-is. There is no "time before releasing source code" concept specified in the GPL license, which makes me think it's supposed to be done immediately or at the very least as soon as someone is requesting it, otherwise it would just be ridiculous since you could basically release sources years later.

grant2258

Well i dont know about the time delay you would need to read up on that but considering it could be posted and such I doubt there would be an issue as long as it is done at some point.

It makes sense to delay for a few weeks when your running a monthly patreon else your just giving someone else your patreon donation potentially will go to another project using it instead. As long as he is releasing it eventually there shouldn't be an issue.

pjft

@quicksilver Interesting. Will look into it.

For me the glitches happened mostly at the 1st end of level boss, when he's shooting the massive lasers. Intriguing that it changes depending on what's been shown or not, though it does map to my experience on Die Hard Arcade as well. On random occasions some sections would be all glitched up, and not on others. Oh well.

There's no 'eventually', the license makes it clear you need to release the source on request:
https://www.gnu.org/licenses/gpl-faq.en.html#GPLRequireSourcePostedPublic

Otherwise, 'eventually' can become years and, de-facto, there's no source released.

grant2258

@mitu it says it must be done on request it doesnt specify a processing time as it can be posted by mail.

In an ideal world it would be right away. I think this is why newer emulators are going closed source or bsd type licensing ts not good in the long term either way but it is what it is a monthly donation for your efforts who gets it you or your competition.
