I'll say that when I see a DC and a 3DO core as well

But yeah, a PSX core would really make my year.

Well console wise we are still missing Jaguar, 3DO, 32X and CDI

As well as CD-32, hopefully that wouldn't be too much work to create, as it is so close to an Amiga 1200.

Can't mention Amiga CD-32 without Commodore CD, which is presumably easier as I don't think it has any special chips, while CD-32 has one that would have to be done.

MY childhood system.

After finally reading the patreon post, it feels like it's a drama between Laxer and Ultra which put the project to a halt...
It's really annoying when people can't keep it together. You understand why so many devs decide to work by themselves and are always unease to bring people in. You never know how people are gonna behave. We clearly don't know much, but it's just f ing sad.

Sad to see it go this way. Would appear from the outside to be an issue about % ownership of the project/proceeds which might explain the "friction".

Disappointed about the news, but Laxer has been very open and forthcoming with all information up to this point and at least all the work Patreons have supported has been put up on GitHub. I hope the community gets the rest too from Ultra.

There are no guarantees with developments of cores and I think most people understand that going in. I wish Laxer the best for his contribution and hope that maybe somebody else will grab the torch.

Meanwhile, there has been new progress in the Saturn core today

Maybe everyone who supported the PSX core development on Patreon should move over and support Sergey.

Not necessarily, I can't speak for either of them but there appears to have been some friction going on regarding implementation of the SPU (audio) side of the project.

Didn't know there was one at all. If I thought the PS1 might be difficult a Saturn core is even more crazy.

ultraembedd expressed on Discord that he'll share his portion of the code this week on Github so if he decides to drop the project it can be picked up. I don't know how far they've gotten, but an uneducated guess would be they completed 40-50% of the project. Robert Piep mentioned earlier on this thread that he'd consider doing it after the WonderSwan, so there is still plenty of interest. PSX will live on!

I hope Laxer comes back to this project.

If not, I might start with PSX after wonderswan.
PSX cannot be left undone.

I salute you sir! What a total badass. Consider me as a patreon if/when you do. And thank you.

Help us FPGAzumSpass-Kenobi, you're our only hope.

Yes CDTV, pretty much an Amiga 500 with a CD drive.

And a remote control

from ultraembedded:

" ## PS-FPGA project
Hi,

I have pushed everything I have for the current version of the PS-FPGA project to our shared repository that Laxer created:
https://github.com/PS-FPGA/ps-fpga

The repo contains submodules (from both contributors), so to clone it, you will need to run:
git clone --recursive https://github.com/PS-FPGA/ps-fpga.git


It contains everything we last demonstrated (unless I missed a file in the commit process), and excludes SPU (sound) and MDEC (fmv) as these are stubs / not integrated.

It obviously targets the Xilinx board at the moment (our development platform), but it should be reasonably straightforward to port to MiSTer provided (a) it fits, and (b) MiSTers DDR has enough BW / low enough latency.

I am taking a break from this stuff but hopefully one of us or someone new will pick up this project and run with at some point."

fingers crossed this core gets a beta release in the next couple years.

ultra's last comment there, about the core being ported from xilinx to MiSTer and if "it fits" is something the next team will have to figure out.
id imagine jotego's new DDR controller could be used, as it addresses bandwidth and latency (altho i have no idea how much bandwidth/latency is needed for the higher performing PSX games)

until then, its more handhelds and arcade cores for the foreseeable future.
which isnt a bad thing, but its kind of what i was guessing, now the MiSTer has reached the end of its limits for core development.

32X, Jaguar, Saturn and probably some other consoles I can't think of right now are still missing and probably doable, although MIA Jaguar and 32x isn't much of a loss game wise imo, but the Saturn development is apparently coming on quite nicely.

Logic wise the arty board that the PS1 team were using and the de10 are quite similar so it'll most likely "fit" with room to spare (can't imagine it even being as big as ao486). Just like ultra put, the question will be bandwidth and latency of the DDR on the De10, if it isn't up to the task then it might be the end of the road for PS1, at least as far as MiSTer is concerned.

Edit. I did actually ask laxer once how much logic they thought it will take up on the De10-nano the answer was something like 70+%.

There is already an early implementation of the Jaguar by ElectronAsh, hopfully he decides one day to finalise it.

We should be happy about what has been accomplished so far.

Seems like the remaining work is mainly about polish. Easier said than done, but Laxer and Ultra did get a lot done. Whoever decides to pick this up will be in a much better position than he would have been otherwise.

Imagine once the psx core is finished using jotego ddr memory bandwidth and then jotego will go and port the DDR arcade using the psx core.

Yes CDTV, pretty much an Amiga 500 with a CD drive.

Its a bit more than a regular Amiga 500. At least hardware wise. It supports remote controllers, and does not support regular mouse or joystick without an expansion.

Also its SCSI based. The CD drive runs over SCSI I think, and expanding it with a hard drive, uses SCSI as well. It also uses a special Kickstart for the boot screen and such.

Its probably not especially difficult to get to work though. I already has added some software ways of running some CDTV games using the Minimig core as it is now in some other threads, using special boot disks. But only some games work using that. I am surprised how much it relies on the CPU being a 68000 CPU. That explains why CDTV games wont run easily on an Amiga 1200.

Yeah, he did an amazing job I think. I do not feel my money were wasted. I had even tried to tell him to take breaks and such. Its all well and good to get Patreon support and feel obligated to put work in, but seems to he overworked himself.

I hope he recovers, and I am just happy that he and Ultra shared their source code stuff. Its amazing how close it is to a working Playstation I think.

I have been donating to the Patreon for a couple of years now, I am obviously sad, but I appreciate the honesty in just giving it up and not disappearing altogether.

I would obviously donate to any other Patreon who would work on the PS1 FPGA project.

same ^

and tbh, laxer is leaving a lot of money on the table.
his generosity with handing over his work like that is equally commendable, and the next team to finish this up will have a great head start !

Unless I'm mistaken it was always going to be handed over to the community as it was eventually going opensource at some point or another. The work by laxer, ultra, electronash and others is amazing.

oh, yes of course!
sorry if what i said was misunderstood.

what i meant on my previous post is that laxer stepping away is leaving a lot of work (and patreon dollars) for someone else to pickup. which is commendable for someone to just hand over the recipe and "leave the keys in the car".

its generous of them to make their work-in-progress open source and available for the public, which may have been made public eventually, but to my knowledge was not handed out during development of a core

Yes doing passion projects can run you into health issues as well. Been there almost, done that, I was glad enough to hit the break at the last minute. But I also did not have the responsibility to run a Patreon on top! So quitting/putting things into hiatus was easier once I could acknowledge, that I have a problem! I hope he recovers. And as well from my side, a ton of thanks for the work.

Truly sad to find out that the work that was being done on the PlayStation core came to a complete halt. Has anybody picked up on this project or it's completely abandoned?

Hopefully SRG320 can do it after the Saturn becoming the 32-bit FPGA God.

https://www.reddit.com/r/fpgagaming/com ... /psx_core/

TL;DR - laxer is still working on it, but at a very slow pace

and yes, it would be amazing if someone like SRG320 would step up to finish the PSX core (or at least help move it along)
