VCD Player for PSX (software based)
Just released my VCD Player for PSX, fully software based, without needing extra video/audio hardware. The VCD player is included in my kernel clone (which can be used as BIOS ROM replacement, or as Expansion ROM, ie. with Datel or Xplorer cheat devices). The kernel binaries are in included in no$ps...

Re: NOCASH PSX-BIOS SWAP
In theory, yes, assuming that you didn't mean CPU pin 22, and that caetla uses only the first 128Kbytes of the chip, and that you've somehow removed the action replay I/O port accesses.

Re: NOCASH PSX-BIOS SWAP
Chip select for BIOS ROM is CPU pin 97. Chip select for Expansion ROM is CPU pin 98 (or Expansion Port pin 4). The latter would map your ROM similar to those used in cheat cards, but of course without reprocuding their internal I/O ports, nor the weird 'paged' memory mapping used in some of that car...

Re: Chipless Modchips
Okay, if that's reliable then I could do that, too. But I still need a tri-state output instead of open-collector, so the 74HC126 chip should be still easiest. At best, I could omit the two wires for the SYNC and WFCK pins, I don't have a PU-22 board for testing the software-generated clock though.....

Re: Chipless Modchips
I am still trying to figure out the best way for the "External Expansion ROM version, for newer boards (PU-22)". It would need the DATA signal and a WFCK signal, and of course the circuit should be inactive when disconnecing the expansion ROM. I have tried to output a merged "DATA+WFCK" signal to th...

Re: SCPH-100 series Service Manual request
You don't happen to have a nicer PU-18 scan by chance? Maybe even a PU-7 / PU-8 *anything*? That'd be great! :) Would be great, I hope that scans show up someday! For PU-18 (aka SCPH-5500/5501/5502/5503), I've spent some days on 'remastering' the existing scan (the one with the messy top-down image...

Re: No red beam on laser - motherboard issue
There's no red beam. It's infra-red, I doubt that any humans could see the beam, no matter if it's working or not. Worst thing I could think of is that the beam might burn your eyes when gazing at it. EDIT: Or well, yes, there's some faintly visible red light when gazing at it from some viewing angl...

Re: UniROM V6 - New stuff and things.
I've recently tested the Secret Unlock commands on a console with japanese/asian cdrom firmware. Of course, the commands won't work, and don't unlock anything on such consoles, and I thought that the console would just ignore those commands. But actually it turned out to be worse than just ignoring ...

Re: Question about rare Dual Analog-controller
There should be some way to get the buttons back working. I don't know which is the best (and longest lasting) method, but some ideas would be cleaning the contacts with contact spray or some other liquids, or 'repainting' the contacts with conductive silver, or search for 'remote control buttons' f...

Re: PlayStation PAL Series Colour/Color Modification (PAL60)
The clock shape (sine/square/other) isn't the issue. The first problem is how to synchronize the color clock to the GPU clock (that will give you a perfectly stable picture with "perfectly stable" color artifacts). And the second problem is how to de-synchronize it again (by adding some small timing...

Re: Question about rare Dual Analog-controller
No, I didn't notice any lag. Or do you mean that ugly 500 cycle delay being needed in the serial transfer? You'll never notice that with the offical kernel - since it's always using that even bigger delay with more than 2000 cycles - no matter what kind of controller you have connected. It's only an...

Re: NOCASH PSX-BIOS SWAP
A19 would be for 1Mbyte chips (the SCPH-5903 actually has that much memory, probably because two teams worked on developing that console, and each wanted to have their "own" 512Kbytes of memory (technically there has been no good reason for using that much memory)). For a 512Kbyte chip, store the 25...

Re: PlayStation PAL Series Colour/Color Modification (PAL60)
That 8pin chip you have there is a PIC microcontroller that you are using to "amplify" the 2pin oscillator? Uncommon solultion, but if you have the PIC in there anyways & think that it should work then it's okay. Otherwise 4pin oscillator would be easier. Also, since you said that the colors came ba...

Re: Read and write PS2 memory card with Arduino
I recommend using resistor voltage divider instead of zener diodes as you get a finer control of the voltage. That method is fine if you need a reference voltage, but it isn't too suitable for supply voltages. The memory card will also act like another resistor wired to ground, so the voltage will ...

He is saying that the flashing tool only works with some chips. In your case, the one with the SST chip.
