In my case, it's two factors.

I don't want to put any more money into playing my PS1 games, but I also love PSIO as a device. I personally find its installation a piece of cake if you're familiar with SMD components, so I don't consider the soldering a minus at all. The cartridge format is wonderful - it fits the console so well and I don't have to open the lid to remove/insert an SD card. Finally, PSIO is capable of a lot of extra features. We only need to get the compatibility up there and a lot of gates will open.
Because we don't know when we will die, we get to think of life as an inexhaustible well. Yet everything happens only a certain number of times, and a very small number really. How many more times will you remember a certain afternoon of your childhood, an afternoon that is so deeply a part of your being that you can't even conceive of your life without it? Perhaps four, five times more, perhaps not even that.

I don't like talk off topic. But.... Why Cybdn make ODE? PSIO not going to be 100% accuracy with games only ODE? Sorry, i just don't get it.

Because it doesn't require any soldering. We will still work on and support PSIO to try and achieve 100% compatibility.

No! Try not. Do. Or do not. There is no try.

Ok... it's reasonable about soldering. Good to have option to solder or not.

Ok, thats i want to hear. It's not good for company business if you drop support or make update very
slowly & not active because of the launch of new ver of PSIO (ODE like). As a result, we were engaged in beta testing so that you release an improved version of psio (ODE like). I think most of us will not be satisfied with this. Just hope this will not happen. :)

Of course. Let's say that I switched shoes and was a customer, bought a PSIO and then the company stopped supporting it, I'd be furious. So yes, of course we'll still support PSIO :)

Well as for a development update, currently we are fixing Need for Speed, South Park Rally, Resident Evil 3 (and the weird DUAL SHOCK freezing bug) and Jackie Chan.

My guess is that MKT will be an easy fix. The game is probably asinine about the timing of CdlDemute.

Ah, yep! We are looking at Mortal Kombat Trilogy now too. I confirmed that is broken. I don't see the programmers (Avalanche Software) actually calling CdlDemute, so CdlReadS may call it internally if the flag is false since that's all I can see when the game is un-paused. We will check what the original HC05 is doing from our disassembly of it.

So long as my PSIO still gets some kind of use when paired with the new ODE I'm happy.

I wouldn't care if you released slow updates as long as you're still making progress, but the updates also seem to be helping you find issues. Double edged spoon, it seems.

Time for another little update. "Jackie Chan: Stuntmaster" is almost fixed and working. We had a major break-though with it and found a major bug in the way the CD results buffering was handled. This should improve some other games too and make them much more stable if the programmers were doing some clever low-level buffer accessing to speed up load times. Final Fantasy 7, Resident Evil 2 and Resident Evil 3 might be some of them. More testing is underway :)

Hell yes! I kept saying the buffering on PSIO is borked. Some of the major issues had to be coming from this bug.

Can't wait to see Jackie fully fixed. I knew that fixing it was the key to maturing PSIO's firmware. I'm so happy you guys finally got hands on an analyzing tool powerful enough to crack this.

We had to make our own tool to analyse it well enough, but we finally got there :)
Once we finish with Jackie Chan, we want to get Vib Ribbon working.

Here's to all our supporters and to us attempting to now try and reach 100% compatibility on PSIO.
