actually we know, how to improve firmware, on sw level. but it can be not enough, for example xa decoder is performed by ARM, so future improvement is to move decoder and other logic into fpga, so the mcu will act mostly like HC05.
additionally, if there's unknown issues, we plan to analyze how original hw works, so the special hw is in development, it's based on original cd-rom ic like cxd1815/cxd1199

Yes. We actually don't know exactly why they are skipping and what the programmers did, but it's most likely because of sync issue with the CD-ROM controller. We are looking into it however and trying to debug why it happens. This is also why Parasite Eve 2 lags and then crashes entirely (it's much rarer now though, but it still does happen).

A dedicated debug board is actually being made by Yuri to diagnose this issue further. Photos soon.
I noticed after the firmware update before last- when you improved CD-ROM Buffering, the skips started happening at faster intervals. from 5-6 seconds to every 2-3 seconds. You guys may be on to something there.

Re: Official PSIO News and Development Thread

I'm considering doing a Frankenstein project on a future PlayStation and PSIO. What I want to do is mount the PSIO internally by removing the 90 degree 68 pin parallel port connector and either replacing it with a vertical mounting replacement or just hard wiring the PSIO directly. A low profile LED would be applied somewhere on the shell wired from the PSIO's current LED access light so I wouldn't lose reading confirmation. So here are my questions:

1.) Is there a vertical mount replacement available for the parallel port? (I looked but couldn't find one.)
2.) In the event that no parallel port replacement is available, is it possible to buy a PSIO without the shell and port connector? I understand that this would be a no-warranty type of sale considering it'd be a bare-decorated PCB being sacrificed for the sake of my little project.
3.) What wire AWG (thickness) would you recommend for this project?

The goal is to have my PlayStation be fully functional with a PSIO, but the PSIO be all hidden underneath the grey shell of the PlayStation. SD card access would be granted by an extension cable via a feed through access slot cut out or something to that effect. Removing the shell of the PSIO would help in working within the limited space internally and may allow me to not cut a rectangular PSIO shape out of the metal plate. Having a vertical mount would help me facilitate this project a bit easier but if I had to hard-wire a PSIO PCB directly to the pin-holes of the parallel port I'm prepared to do so. I'm OCD and have a lot of free-time on my hands so this could either be very bad or very good. :lol:

New improvements have been made to the firmware. Final Fantasy VIII (8), Team Buddies, Road Rash Jailbreak and Rollcage have all been fixed. An update will be released later today...

As for your question MateriaMind,
1) No.
2) Yes, but not at the moment. I want to design a special version for use for such applications (also for the PSone too).
3) The same as the Switch Board. 28 AWG.

Excellent- Glad to hear this, thanks for your response!!! Also, thanks for both of your guy's work on the upcoming firmware. I'm off on weekends so consider this weekend being solely dedicated to testing!!!

I don't think it was actually submitted, but the new firmware will most likely fix that issue also ;)

I'm using Kinston SDXC 128Gb card. No problems so far. This is a card which is unofficially confirmed to be working.

I've been using a 64 GB card without any issues. Thing is, PSIO doesn't technically support SDXC because it doesn't support exFAT. A special program is needed to use FAT32 on cards greater than 32 GB, which makes it a non-official way of using such cards. I'll need to verify with Yuri if the FAT libs we coded are even setup to address such a highly formatted value...

Note: Tempest X3 has been fixed: http://www.cybdyn-systems.com.au:82/browse/CSGC-7

The new firmware will be released tomorrow, alongside an updated Menu System.

Does that mean that you can just use the 32GB of a bigger than 32GB card or that you'll be able to access all of the storage?

You will be able to access all of the storage.
The reason why 32 Gb is maximum officially supported is because it's maximum size of SD card that can be formatted in FAT32 using standart tools in Windows 7. More than that defaults to exFAT, which is not supported by ps-io.
I have successfully formatted my 128GB in FAT32 with EaseUS Partition Master.

Correct. That's why PSIO says it only supports a maximum of 32 GB because it's the industry standard. Windows can't format anything over 32 GB unless it's exFAT which PSIO does not support. So, what I'm thinking of doing is actually adding a FAT32 formatter to the Systems Console program so that users may format cards greater than 32 GB, and I will update the manual, box and guides to include this new information when it's done.

I meant by extension Yuri as well, I keep wanting to revert back to the old Shadow and Cybdyn monikers. Both of you guys are definitely in a league of your own.

Ah, sorry. I just like to make sure I don't take all the credit because Yuri is a big part of it all :P
Haha, yeah, but because we've grown into a business, we've had to take a more professional approach ;)
