Introduction
This topic aims to guide you through the installation of the chip "Delta SmartWave" in your Sony PlayStation 1 console.
Features
The Delta SmartWave allows your console to automatically adapt to the GPU frequency and video subcarrier based on the region of the inserted game (50Hz or 60Hz).
If you try to play an imported game (e.g., JAP) on a European (PAL) console, you may end up with a black and white screen. This is due to the incorrect timing required by the game compared to what is present in your console.
A 60Hz game (JAP or USA) should normally be played on an NTSC console.
A 50Hz game (PAL) should normally be played on a PAL console.
Thanks to the Delta PSNee (available at the
Delta Store >>), you can play all games on your console.However, the console's frequency is not modified, which results in black and white images.
Some people use an RGB cable to improve the quality of the video signal.
The RGB cable will return color to your games, but will hide the frequency issue. For purists and OSSC owners, it is essential to correct this.
That's where Delta SmartWave comes in!
Through intelligent detection, the Delta SmartWave automatically adjusts the GPU frequency and video subcarrier with great precision, correcting all the previously mentioned issues.
With the combination of "Delta PSNee" + "Delta SmartWave," you will have the ultimate console—no need to own three different consoles for each region (PAL, JAP, USA).
Finally, we remind you that Delta SmartWave was designed to be soldered without cables!
Delta SmartWave est plus precise et plus intelligente que :
- PS1 MFO / MOFO (Multi Output Frequency Oscillator)
- PS1 DFO (DUAL Output Frequency Oscillator)
No need for programming or unpleasant surprises like the mods mentioned above!
Delta SmartWave is an intelligent solution that adapts to all situations, without asking any questions
Delta SmartWave: A Major Advancement Over Traditional DFO (Dual Frequency Oscillator) and MFO (Multi Frequency Oscillator)
1. An Intelligent Microcontroller for Precise Adjustments
As the name suggests, the SmartWave is “smart.” It features a microcontroller capable of automatically detecting the console version (PU-7, PU-8 early, PU-8 late, PU-18, etc.) on which it is installed. This allows it to precisely adjust its frequencies to match the technical specifications of each model, unlike DFO/MFO, which do not cover all variants, such as the PU-7 and PU-8 early.
2. Universal and Automatic Compatibility
Frequency management varies between PlayStation versions. While DFO/MFO often require modifications or are incompatible with certain models, the SmartWave automatically detects the region and console characteristics, adjusting to the correct frequency (PAL 50Hz or NTSC 60Hz) without manual intervention.
3. An Ultra-Precise Frequency Generator
The SmartWave integrates the most precise frequency generator available to date, ensuring perfectly aligned frequencies with the original specifications of PAL and NTSC consoles. By comparison, DFO/MFO use approximate frequencies, often with high decimal values. While functional, they are significantly less optimized.
4. Easy Installation and Optimized Performance
Unlike DFO/MFO, which may require complex manual configurations, the SmartWave is easy to install, without additional wiring (*one wire required for PU-7 and PU-8 EARLY). Once in place, it operates autonomously, offering unmatched precision and eliminating video synchronization issues or black-and-white display problems.
The Issue of Regional Frequencies
When a PAL PlayStation is used with an NTSC-J or NTSC-U/C game and the original composite video cable, the display appears in black and white.
An RGB cable can restore color, but this only solves part of the problem…
The real issue lies within the GPU (Graphics Processing Unit) and the video subcarrier:
1. The console’s GPU is clocked differently depending on the PlayStation’s original region.
2. PlayStations use region-specific crystals (PAL or NTSC), which can lead to underclocking or overclocking depending on the game being played.
This discrepancy, while subtle, is noticeable:
• The GPU and other components do not operate at their optimal frequencies.
• This can cause slowdowns or a loss of fluidity in certain games.
Why Delta SmartWave is Different ?
Delta SmartWave directly adjusts the GPU clock frequencies and the video subcarrier.
Thanks to its intelligent management system:
• It automatically detects whether the game is PAL or NTSC and adjusts frequencies accordingly.
• It restores perfectly aligned frequencies (PAL 50Hz or NTSC 60Hz), eliminating any underclocking or overclocking.
In Summary
Delta SmartWave vastly outperforms DFO and MFO in terms of precision, compatibility, and intelligent frequency adjustment. It offers an innovative plug-and-play solution that adheres to the original console specifications, delivering an unmatched retro gaming experience.

1 - Identification of your PlayStation console
First, locate the label underneath your PlayStation console.
On this label, identify the model of your PlayStation.
In this example, the model is “SCPH-7502”. While this reference provides important information, we need to verify the exact motherboard revision.
To do this, we will need to access your console’s motherboard.
2 - Disassembly of the PlayStation console
Below, you will find various videos.
The goal is to access the motherboard. You do not need to disassemble the console’s power supply. Please do not touch it!
3 - Identification of your PlayStation motherboard
Please identify your motherboard using the following photos :
