PSIO Supposedly Working

My 2p on this:

1) Compressed images would take too long to decompress each time you wanted to run a game, since alot of PSX games are quite small anyway i dont really see the need to compress them, personally i think the investment of £75 for a 2TB hdd to hold the games is worth it

2) again i dont see the need to have auto-patching such as this when you could quite easily patch them on the PC first -it would be quicker and you would have more tools available to make the changes you wanted.

3) Playstation lasers read at 1x or 2x i cant remember which it is so it would be very slow in making a full backup, again its just quicker to do it on the PC at 52x or whatever they read at nowadays, plus im not 100% sure i would trust an image created from the playstation itself unless you knew the laser was perfect which i doubt many of them are these days

just my opinion

 

A great design choice IMO would be to replace the cd-rom optical board completely (if it's discrete) or the laser assembly and replace the laser assembly by a sd-slot/usb port accessible when the lib is opened! That'd be rad!

 

..

 

This was discussed on DC-SWAT forums in the past, but the thing is, that CD assembly connects to board by analog bus, and CD circuit is onboard, so this thing could be possible only by connecting to digital signals inbetween CD circuit and main system. And moreover, PSX parallel port has all needed signals, and it's solderless, so no reason to replace CD assembly.
On the contrary Dreamcast has CD circuit separated, so it will be possible to replace GD-ROM with "DCIO", or how it would be called .

 

You could do it by feeding it analogue signals. There are pro's and cons to the using the parallel port, but it should work.

 

You're not hardware engineer, right?

This is hell to implement.

 

@RetroJunkie

You not recieved it yet? ..Taking their sweet time getting it to you aren't they.

 

Oh, yes apologies for not updating the thread - real life sure can be a pain!
We're waiting on an FTDI serial cable to help with debugging something or other.

Then I'll have to find video to make videos and such... when it does arrive I might take a few days off work to enjoy it! (INSERT SMILEY FACE HERE)

Good luck (This kinda works ;oP )

 

Unfortunately, it will not support HDD. I was told at the beginning it would be but the PSIO team dropped support for it. If you wanted to be hardcore about it though, you could get the Lexmark 256gb SDXC card and format it to fat32 (as long as PSIO supports fat32) and it should work. I'm considering getting a 128gb card myself for PSIO.

 

SD cards around that size are incredibly expensive. I'm not spending £200+ on one that's for sure. I'll wait and see what happens further down the line. I'm sure HDD support will come eventually.

 

i discover new ARM mcu w/ usb host feature. so, theoretically you can plug any USB storage device : usb flash, usb hdd, usb card reader...

 

Cool. Coming from a potential customer, it's a must in my opinion. I'm guessing most people on here would choose HDD over SD card every time.

 

how y play on PSP)))

 

Haha, does this mean the hardware that will one day be en route to me is already outdated? ;D

 

you will get reall thing. we only plan work w/ ARM.
also , you can be potential tester of new version. if plan become real.

 

If the mcu is from the same family i see no problems software and hardware wise, there are diferences between arm cores. Is that other mcu from the same mcu family? Example, nxp cortex-Mx

 

tusb3210 is 8bit c51-core mcu.

 

Just noticed the PSIO and DCIO threads are both tied at 27 pages each! What are the chances?
Also the PSIO hardware rev 1.1 has shipped and is on the way, should be with me either tomorrow or Friday.



Edit: Captain Awesome is my neighbour, he often gets mail for me while I am at work. He's on a pension and stays home most days.
Edit 2: Wait, that's the wrong way around. Does that mean I'm on a pension? It's late...

 

Nice to see that it has finally arrived! Is that an old IBM PS/2 keyboard in the background? Those are my favorites and I've got a box full of them.
