Re: Part number / identifier for PSX Parallel port

There is no part number for the parallel port. It was a custom connector used by Sony with a similar design to an old SCSI connector. The only company manufacturing this connector is Cybdyn Systems which they use with PSIO.

Re: NO$CASH Kernel Clone - New Expansion ROM Version

Sure, but please ignore my terrible handywork with the switch I used and how it was soldered in. It was a rushed job :oops: Basically the switch enables or disabled the mod. Hope it helps you :) http://www.psxdev.net/forum/download/file.php?mode=view&id=1381 http://www.psxdev.net/forum/download/file...

Re: Sony DTL-H2000 Troubleshooting, Info, Setup, Parts & Help

About the controller port, why is it needed to cut the board in half ? Can we wire each of the 2 ports to each controller ports on the board ? (after cutting in half) In the case with the DTL-H2000, the controller ports are separate but the board of the PS1's controller ports links both ports toget...

Re: Tilemap best practices

The trick here is to use a little instructions as possible so for every cycle of the clock, the system doesn't executes unnecessary opcodes which the compiler may have added in from the C or C++ code. On a processor like the PS1, reducing the number of instruction is not the biggest optimization, t...

Re: Tilemap best practices

You can code in C or C++ (doesn't matter). What it comes down to is how well the compiler can optimise the high-level code to low-level code. When you know the compiler isn't doing a good job with your routines, that's when you write it yourself in assembler to get the most performance out of the sy...

Re: NO$CASH Kernel Clone - New Expansion ROM Version

I think this is the reset line or interrupt line. I can't remember, but NO$CASH used it to tell the PlayStation when to start accepting data.

Yes. Exactly. It actually takes proper skill unlike programming today on machines with speeds so fast that well structured code and optimisation isn't required.

Re: Generic Power Supply

Hm, I've got to disagree on the looks of this supply. To me, it looks like a cost reduced clone of the original. I can't say much about the primary side, but look at the secondary! Where is the reset controller IC and all the filtering passives? The capacitors look small, and all I can read on one ...

Re: How to dump your CDROM BIOS (Firmware)

Why are you using your dumper program? Just use the one built into the HC05. Or am I missing something here?

Re: WTS:EmulationStation+Kodi PlayStation - Octa Core ODroid XU4 - 200USD

Cool project, but It's cheaper to spend $110 USD on PSIO and use the original Sony hardware which will give you much higher compatibility :)

Re: Code Injection into Existing PS-X EXE files

Thanks for the reply Shadow. As for your first point, I'm not exactly sure what you mean. What is the advantage of patching in a PS-EXE running on the arcade hardware before the game boots, when I can do it on my PC instead? A trainer is not quite what I'm looking to build. This is not a program th...

Re: DTL-H1001H

I've got a PAL PU-8 with the 40-pin HC05, but no S-Video. You's seems to be the Japanese model though, so that makes sense.

Hmm, could be! It looks like some sort of regulator or transistor. It's hard to tell if it's going to alter the video IC or motor driver IC. The photo is too blurry.

Re: How to dump your CDROM BIOS (Firmware)

Best thing to do would be to eliminate your Teensy microcontroller dumper and see if the HC05 is even outputting data. If you have an oscilloscope, I'd pop it on there and have a look. Otherwise, grab yourself an FTDI (IE: use something which doesn't require code to function). http://www.robo-dyne.c...

Re: DTL-H1001H

They replaced the HC05 with one that was programmed with the security stuff removed. Sony would have had a stock pile of them at the time and they just swapped them with generic PU-8 boards. The chips can still be bought blank from suppliers, so in theory, they could be programmed with the ROM that ...

Re: Code Injection into Existing PS-X EXE files

Why not just make a PS-EXE that loads before the 'Dance Dance Revolution EXTREME' PS-EXE, do your hacks, and then execute the 'Dance Dance Revolution EXTREME' from your PS-EXE as a new process?

As for injecting the code, what you want is a trainer. There is one on the forums here that you can use.

Re: How to dump your CDROM BIOS (Firmware)

Strange. My ISP is Telstra and I'm using Cloudflares DNS. Never had a problem with them.

Why did you have to code your own TTY handler. Why can't you just use a serial window and dump it directly (IE: echo all bytes received)?

Re: How to dump your CDROM BIOS (Firmware)

I did all that, as you can see on my photos. the only thing I did not is letting RX pin high at boot. As I said, I can't see your photos.
