PS1/2 Citrus3000psi's PS1Digital is coming along (DCHDMI / Wii Dual guy)

Looks spectacular ! second video shows lag free switch between 240p and 480i menus

I'm still not sure how much this is going to look better vs to a CRT, but it definitely looks like the best solution for flat screens by far and I love my DCHDMI to pieces (but I think 480p scaled translates very well even 20 years later, Dreamcast was truly ahead of its time)

Some info about this.

Like the DCDigital before it, the PS1Digital will also have WiFi functionality. The DCDigital currently only uses this chip to download firmware updates directly from the DCDigital project, but the PS1Digital will expand upon that functionality by doubling as a wireless Serial I/O Port. Considering that the PS1Digital replaces the PSX’s Serial I/O Port with an HDMI connector, this is a relief for users that enjoyed the Link Cable multiplayer features in some games. As an added bonus, the WiFi chip in the PS1Digital has been upgraded from the one in the DCDigital, providing a faster and more stable signal.
The FPGA in the PS1Digital has been upgraded from a MAX10 to a Cyclone10. The takeaway here is that the Cyclone10 operates at a lower temperature and provides more resources to the PS1Digital’s dev team, which could lead to an expanded feature set—advanced deinterlacing for 480i games and improved scaling algorithms, for example.
The PS1Digital has mod-chip functionality built in, which is based off the open source PSNee project. This functionality circumvents the PSX’s copy protection (all consoles) and region coding (NTSC-U and PAL consoles only), allowing you to access the PSX’s worldwide library. The PS1Digital can also generate its own clock signal, which has the affect of letting your PSX switch between 50Hz and 60Hz output depending on the software you’re running. To reiterate though, NTSC-J (aka, Japanese) PSX consoles have added region checks that the PS1Digital won’t be able to circumvent, so those consoles are only able to run NTSC-J games for now.
Dan confirmed that only SCPH-55XX and 70XX series consoles are currently supported, and may be the only consoles ever supported by PS1Digital. The PSX hardware platform has a staggering number of revisions and some of them simply don’t expose the digital signals that the PS1Digital needs to generate its HDMI output. The current mod requires four flex cables to function, so any accommodations for other console revisions would likely require a massive redesign. If the PS1Digital is a mod you’re interested in, it’d be a good idea to find a compatible PSX instead of waiting for the possibility that support would expand.
Lastly, the PS1Digital’s installation and operation shouldn’t conflict with the modifications required for the PSIO. For those unaware, the PSIO is a Playstation optical drive emulator developed by Cybdyn system that uses a mod chip and external hardware to run PSX games from an SD card.

Thanks for this, this is great info to impart on top of my lazy post haha

and I am aware DCHDMI = DCDigital now naming convention wise, but many of us are just used to calling it DCHDMI

--

People asked on twitter if it would be compatible with PSIO, and Dan confirmed it would and all of his testing has been done with a PSIO'd PS1.

Really looking forward to this when it launches. I'm hoping it supports more versions but if not I'll have to go find myself a cheap system for this!

Damn that's nice. They were working on a PS2 version as well but haven't talked about it in over a year.

They had a working prototype, but they decided a while ago that they wanted to make the PS1Digital before they released the PS2Digital. Hopefully this means that the PS2Digital won't be far behind

Thanks for the info! Didnt know that. Hopefully it follows soon!

Preorder price of $160

the combo of this and XStation ODE looks like PS1 is getting some much needed love at last

So it seems the PS1Digital will hit the shelves soon; Citrus3000psi wrote on his Twitter account that the first batch was on their way for those of you who don't follow his Twitter account. In the replies he also said the progress had been slow for the PS2Digital and that it would probably be finished some time in 2021

I know (but forget the exact details) that gamecubes display gamecube games better than the wii and wiiu can - and so getting a digital signal out of the gc is the basically the best you can get.

the ps3 can play ps1 games right? how does it compare to that?
I guess the ps3 emulates them, the one(!) game I tried played and looked fine though.
I know native is always nicer, just curious how 'experts' think about ps1 video on ps3.

PS3's PS1 emulator is a bit weird. It seemingly adds a slight blur to the image depending on the game (and wether its digital or disc based!). Sometimes it's razor sharp, sometimes you get the blur. No way to change it.

It's also got some noticeable input lag.

It's got quite nice scaling too up to 1080p, although not integer, which I think the PS1Digital does do, so the image looks crazy sharp on the PS1Digital.

I would say the PS3 is the most straight forward way to play PS1 games for the majority however.
