Re: Hilarious comment this morning by gf...

Maybe your girlfriend is a C programmer but you're a SmallTalk programmer? That sort of thing is forever causing off-by-one errors.

Re: Extract 3D models/Tools

I suppose this is the Blender PSX support: Impressive, but sadly the tense is wrong: The Blender Game Engine originally was able to deploy for the Playstation One architecture. This video shows the demo CD made by Ton Roosendaal to attract investors to Blender. A working playstation with the demos ...

Re: Playstation SCPH-1001 Laser

Just an FYI, I have a couple DTL-H1101 consoles and they feature the poor quality laser assembly. There doesn't seem to be a PlayStation without a poor quality drive, at least when compared to CD players as a whole. Saturns never seem to have any sort of problem... maybe that's where the extra $100...

Re: Playstation SCPH-1001 Laser

My understanding was that, electrically, the different mechanisms are interchangeable — with only the physical aspects changing (length of cable, whether it has little feet, a few millimetres here and there in shape around the top). Is that not the case? Anyway, I took the easy way out and ordered a...

Re: Playstation SCPH-1001 Laser

I replaced worn out laser unit couple months ago, cost about 15 dollars. Got it from here: dx.com OEM-quality product and works fine. And they even got the different versions of it, because there's different kind of drives between the SCPH-models, so make sure, that you open your machine and read t...

Re: How to disassemlbe/edit PSX BIOS ?

The BIOS has got nothing to do with how modchips work (not including stealth). Modchips were made by hackers reverse engineering the system to know exactly what they had to do in order to get the PSX to boot copies. They spoof a signal between the CD drive and the outer hardware to make it look lik...

Re: PSX Blaster (USB Comms Link)

Should we still expect prebuilt blasters to become available? If so then what's the relative timetable versus PSIO? Will one become available before the other?

Re: How to?

It sounds like possibly you don't know how to program in general? If so then the PlayStation isn't a good learning platform. The tools are awkward — the compiler is out of date (especially by virtue of predating C99) and you're unlikely to get a debugger to work. I don't think there's any means to p...

Right. Here's a bootable ISO and the latest EXE. This project has now been tested on real hardware and a screenshot from there, in glorious composite, is attached. I also threw in a few more ships, as I continue barely to tax the hardware despite hugely inefficient code. That second bit is why I hav...

Replacing the SCPH-1001 CD drive

Backstory: I haven't owned a PlayStation for about a decade. I bought one in pursuit of this hobby. Being useless at soldering, I therefore needed a modded one. It's an SCPH-1001*. Per the desire to avoid crazy prices, I went to Craigslist rather than eBay. The seller warned me it was a little tempe...

Re: Testing interlaced code; no real hardware to hand

Although the topic has strayed into much more interesting territory in the interim, I just thought I'd mention that I've managed to try the latest version of my code on real hardware at last and all works well. I threw what I had into the Codeblast competition because at the time there were no other...

Should I reply to myself? I've no idea of the etiquette.

I'm sure it won't be your code at fault. Either No$PSX (less likely) or my setup (more likely) will be to blame.

I hope to be able to see the video soon.

Does PsyQ expose the furthest extent of your .exe...

... or in any other way provide such information as would allow the arguments required for the InitHeaps to be obtained automatically? Or do PlayStation .exes not work like that? Are they theoretically relocatable?

Re: SDK Project part 3 Sonic

It gets this far and then No$PSX hangs, on my machine anyway. So, ummm, it's not for that emulator. On my machine.

Can you describe the program more in depth anyway, for the curious?

Re: A noobie question

Good, so we all agree that if we were to take a poll "does the PS3 have anything to do with PSX/PS1" then the overwhelming answer would be 'yes'. Putting that unhelpful detour aside the question stands: does the PS3's PS1 emulator, of whatever quality, run CDRs if the console itself is a developer/t...

It's:
  • made by the same company; and
  • designed to play commercial PS1 games.
All versions of the PS3 are explicitly sold as backwards compatible with the PS1. Many people therefore use them for playing their classic PS1 titles.
