Re: [WTB] NTSC Video Oscillator

You can find these oscillators on aliexpress. they're much bigger though, but you can glue the oscillator to the rf shield and route the wires through to where you hook up the signal. Here's an example of how I do oscillator mods on PS1s: https://retrofreedom.com/ps1dfo.html NOTE: It's not exactly 5...

Re: [Hardware Mod] NTSC/PAL reference oscillator mod for PU-18

hey there :) I have a similar tutorial on my website. How to have dual 53.2 and 53.69mhz GPU clocks for correct PAL and NTSC timings. https://retrofreedom.com/ps1dfo.html BY THE WAY: On PU-22 boards and up, colour subcarrier is fixed regardless of oscillator fix. You also therefore need to mess with...

Video tutorial: How to get pure RGBHV (Red, Green, Blue, Hsync and VSync) output on a PS1 SCPH-75XX

Hi everyone :)

Thought I'd do this video:
https://www.youtube.com/watch?v=_-Xs0QJ ... e=youtu.be

PS1 natively supports hsync/vsync output (aswell as csync) on its GPU. This video documents it.

Hope this helps someone!

Re: Forcing NTSC mode in BIOS on SCPH-1002 PU-8 PAL PS1 (with the older 160-pin GPU)

NoCash specs say this (see: https://problemkaputt.de/psx-spx.htm) - I only connected pins 3 and 4. I'm curious: does the onechip actually analyse instructions going through or... is it just a timer (so are pins 2 and 7 clock signals? I'm gonna find out!) NTSC-Boot BIOS Patch Typically connects to tw...

Re: Forcing NTSC mode in BIOS on SCPH-1002 PU-8 PAL PS1 (with the older 160-pin GPU)

starting new post due to different subtopic... The reason I'm wanting to do this is because with the oscillator changed, PAL subcarrier will no longer be correct (but NTSC one will). I guess I *could* lift cxa1645m's pin 6 and 7, pull pin 7 high and hook up either: * pin 6 via 3.58mhz oscillator. ak...

Forcing NTSC mode in BIOS on SCPH-1002 PU-8 PAL PS1 (with the older 160-pin GPU)

Hi, I want to do this but can't seem to find the info anywhere online, not even pinouts. My aim is to do what the OneChip does on PAL PS1 slim, whereby it forces the BIOS into NTSC mode. The reason I wish to do this is because I want to hardwire NTSC mode on the CXA1645M video encoder by lifting pin...

Re: chipped PS1 and PS2 consoles for sale via minifree.org (and PS1 PSIO installs)

I see. So it's just a bunch of pricks ripping people off. I'd stick with the official PSIO product anyway. While I have some dislikes of the author (judging from the tone of some of the things he writes on his website), the PSIO is *awesome* BTW, I actually ordered a PSIO but forgot. It arrived a fe...

Mod HOWTOs: clean CSYNC (better RGB quality) and dual PAL/NTSC oscillators (fixes TV compatibility)

Hey everyone :) I'll get right into it. All of the information here is based on my reading the PS1 hardware schematics and from doing my own signal analysis (multi-meter and scope) NOTE: dual PAL/NTSC oscillator fixes vsync timings on both PAL and NTSC. On PAL console you cut trace to 208-pin GPU's ...

Re: chipped PS1 and PS2 consoles for sale via minifree.org

i find the homepage of psio really annoying though. right now it says: PSIO is a Flash Cartridge that plugs into your PlayStation’s Parallel I/O Port. It allows you to instantly see your games running from an SD Card on real hardware making it the only way to genuinely play backups on your console. ...
