PSIO Supposedly Working

I don't see any menu on the video. The Playstation loads code from any device connected to the Parallel port (like AR), but on the video, I only see the Playstation Bios.
So, when does PsIOS run?

 

It looks like it's an 8052 derivative - same as in the Cypress parts.

 

os in progress, it's software part and can be developed separately. you can even ask Gemini or tails (if they still wanna help ppl, not only blow sh..t here out of proportion), or you can do it yourself. but i can launch game from SD. not all but list is expanding time by time... cause there is no original information about handling of all cd commands. all discovers from practice. so theoretically, after a while we plan send/sell prototypes to testers, or who wanna add to them.

 

Yes, but you must have your code running somewhere, so, where ?

 

dont get the question... psiOS is code for ps1 and it's running like bios does.
psio is hardware- emulates cdrom drive by mcu/fpga + sd card

 

So.. is it really going to be SD card only? Or it will have a SATA interface?

You know PSX games isn't that small to fit a bunch on a SD card. It would be sweet to be able to use a 500gb HD for hoarding )))

 

Currently the PC tells PSIO what to load from the SD card. The PsIOS menu currently doesnt run (at least not in the videos)

 

pc just sets base lba address of image. in future psiOS show files/images names and launch game w/o pc. also pc loads firmware to mcu - in future by serail eeprom

sata possible - TUSB9261. also usb host by SAM3X. dont know when/what we got success but - work in progress... pcb is on the way

 

Not directly related to PSIO but is it known to be possible to feed the hardware CD audio, XA audio, and FMV through the parallel I/O port? I recall seeing there are audio inputs on the parallel port. But are XA audio and FMV read by the cpu and then fed into the decoder/other hardware? Or did the cdrom controller do that itself? I'm just curious is there really the potential to achieve results that match using a real CD. Same loading speed, no streaming issues with FMV, XA, or Red Book audio.

 

As far as I know, SD card only. I would expect SDHC of course, hopefully as high as 64GB will be compatible. SDXC maybe not. CD/DVD based media games are a different animal than cart, no flash maker can be expected to support that kind of storage.

 

xa/cdda will be decoded inside of psio. pio has serial sound interface - pcm style. i like sound not less than all of us))

 

what is SDHC? for example i use 16gb card - i think its sdhc - so it works. i mean - i dont see big difference on level of access to sd card - just read data from it. maybe there is limitation on file-system level - but it all can be solved. about sdxc - same : is there anyone can explain difference of sdxc and sdhc/sd on hardware /software level. i think - fpga can realize any kind of interfase you ever want.

"flash maker" - what is it?

 

Seriously?

 

i know what is this - under this question i mean what unusual in this card?. and i wrote i read data from 16gb card - that means psio can load from sdhc)) cause under SD - I mean all type of card : sd , sdhc... maybe sdxc

about sdxc i know less - so i asked someone who know?

 

SDXC cards using uhs 1 speed (most 64 gb ones afaik) can be formatted to fat32 (they come with exfat originally) and used just like SDHC cards. afaik sdxc cards using uhs 2 speed are not backwards compatible with SDHC cards so they need different hardware, not just reformat.

 

ok, i read also in googe))
i think we can make OS with supporting exfat - anyway it's a task for software level. another things if it uses some kind of complex/high speed transmitters: like LVDS or pairs , so current chip cyclone 3 from altera can't do it properly at high speed - but maybe main goal just read data at several speed - so it can work, if not we need use cyclone4 or mcu with sdxc controller... we will see

anyway - i notice how fast SD (hc, xc) can be - it can make hardware easy - as i remember ones ask why psio not use extternal buffer. with fast sd we can use less harware at all - almost direct reading from sd card

 

hummmmm.... CF support would give people the option to get at least IDE HD to work. And maybe SATA via an adapter.

Kind of like the original xbox.

 

IDE is a beast. soon it will be buried by Serial High speed interfaces at all.

 

That's two different things. Worrying about possibly having a disease is not the same as having your own explanation (theory) for something.
If you have a theory of a conspiracy as an explanation for an event, you believe that and that's it and it doesn't have to be in plural.
Conspiracy=A joining or acting together, as if by sinister design. Theory=a 'proven' hypothesis.
You don't go around worrying about it like a hypochondriac.

That's nonsense, just like saying a gamer could mean the sort of person who hangs out on unseen64. A gamer is someone who plays video/computer games on a regular basis, if that person reads gaming media or not is a totally different story.
The people you're talking about are usually refered to as "crazy" and have nothing to do with neither conspiracies nor theories.
Why are you afraid? Maybe you need to ask the wizard of oz for courage..

 

Not sure if SDHC is compatible with SD, I know the program for GC (swiss-gc) has to have different code to support SDHC cards.
