PlayStation - Delta Smartwave

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.

The DreamTray is an extension designed for your Sega Dreamcast equipped with a GDEMU. It fits into the empty bay left by the GD-ROM drive and allows you to relocate the SD card slot, secure handling, improve airflow, and add advanced features.

🌀 Restored airflow 💾 Relocated + secured SD ⬆️⬇️ UP/DOWN buttons 💡 LEDs (Power / Detect / Access)

Key points

🔧

Installation
Easy if you’ve already soldered before (2-pin header).

🧊

Mandatory
Console powered off + capacitors fully discharged.

🎮

Disrupted internal airflow

What DreamTray adds

Cleanly closes the GD-ROM opening
Restores airflow closer to stock behavior
Relocates the SD slot using a dedicated extension
Adds two UP / DOWN buttons
3 LEDs: POWER, CARD DETECT, SD ACCESS

🛒 Available now: Delta DreamTray

Get the DreamTray from the Delta Store: a clean, durable solution to relocate and secure your SD card, restore airflow, and add UP/DOWN + status LEDs for a smoother GDEMU experience.

→ View / Buy Delta DreamTray

🔒 Important safety instructions

⚠️ POWER OFF is MANDATORY

• Completely unplug the console (power + cables).
• Wait several hours for capacitors to fully discharge.
• Never work on a powered console.

👉 Read the full safety guidelines

Step-by-step installation

1 - Disassembling the Dreamcast

Goal: access the GD-ROM bay

• Remove the modem

• Remove the 4 bottom screws

• Lift the top shell

2 - PCB preparation

Goal: add the 2-pin headers

Note: solder joints must be clean. Inspect with a magnifier and avoid any solder bridges.

• 2-pin header on the DreamTray PCB

• 2-pin header on your GDEMU (not included)

3 - Connections

Ribbon cable + SD adapter

• Connect the ribbon cable to the DreamTray PCB

• Connect the SD extension

SD adapter connected to the ribbon cable

4 - Mounting

Positioning + bracket + screws

• Place the main PCB into the shell

• Add the retaining/support PCB

• Secure using the 3 included screws

5 - Reassembly

SD connection + Dupont cable + closing the console

Important: the included DreamTray ↔ GDEMU Dupont connection cable is required for the UP/DOWN buttons to work properly.

• Insert the SD adapter into the GDEMU

• Close the console and reinstall the screws

• Insert the SD card into the DreamTray

Inserting the SD card into the DreamTray

Testing the UP & DOWN buttons

The GDMENU software does not handle button inputs in real time (just like the original GDEMU button). To test the buttons with real-time feedback, use the Dreamcast BIOS.

Procedure
1) In GDMENU, press Y
2) Select EXIT TO SYSTEM MENU
3) BIOS → MUSIC
4) Test UP / DOWN (GDI/CDI scrolling)

✅ The buttons remain 100% functional in-game.

Diagnostics

If your GDEMU clone has SD detection issues, a small solder bridge may be required between two specific points. This fix improves reliability on SD sockets of variable quality.

This tutorial is for the Everdrive V3 Krikzz or Chinese clone
BE CAREFUL, krikzz's OS V2 Firmware will brick ALL Chinese clones, even some Everdrive made in Krikzz

1 - Everdrive MD V3 bricked!

You tried to update your Everdrive MD V3 with OS V2 from krikzz and you had this red screen:

Here you are now with an Everdrive that no longer works! It is bricked!
Despite a return to OS V1 & access to the everdrive menu, just after loading the ROM of a game it is a black screen.
Your everdrive will be able to play master system games without any problem. But no more Megadrive / Genesis roms...

2 - Why my everdrive is bricked

Krikzz has put a security system on OS V2 for everdrive MD V3, which makes clones unusable!
Yes, it is krikzz's desire to destroy the clones!

Even some official Krikzz everdrive were affected!

Here is a snippet of the OS V2 source code:

Don't panic, we've found out how to fix your Everdrive!

3 - How to unbrick the Everdrive V3?

The krikzz OS V2 modifies the code contained in the flash memory of your Everdrive.
To be able to unbrick it, we will have to reflash the everdrive flash memory to restart the loading of the Megadrive ROMs.

4 - Reinstall OS V1 on your SD card

To re-install OS V1:

1 - Format your SD card in "FAT32" format
2 - Create a new folder named "EDMD" at the root of your SD card
3 - Copy the OS V1 "MSDOS.BIN" in the EDMD folder (available for download HERE)

5 - Reflash the flash memory of your everdrive

OS V1 is in your SD card, however your everdrive's flash memory is still bricked.

We will therefore have to reflash this flash memory.
To do this, open your cartridge to gain access to the circuit board.

Locate the flash memory which is named "M29W640".
Now you have to desolder it, we recommend that you use a hot air station to do this!

Once the operation is successful, we are going to need a programmer.

We recommend the "TL866 minipro" programmer, but any adapter taking into account the SST39VF040 chip will do.

To properly reflash your everdrive, you will need an uncorrupted dump:
You'll find it here

Then flash your memory using your programmer:

Resolder the flash memory on the print circuit:

And enjoy the megadrive game library on your everdrive which has recovered all its functions!

Many GamePark 32 fail one after the other for no apparent reason.
Here is a tutorial that will allow you to repair your GP32.

1 - Symptoms

The symptoms are always the same:
Many people have noticed that their GP32 does not start after a longtime of inactivity (Blackscreen and red LED on).

First check to do: New battery and no oxidation in the battery compartment!

2 - The problem

After appraising and repairing several GP32s, we decided to publicly share our discovery.
The problem with GP32 BLU, BLU + and FLU is the quality of flash memory.

Over time, flash memory will corrupt on its own until it has floating bits. This corruption appears when the organs power off.
The flash memory responsible for this problem is named: AT49BV040

This GP32 onboard flash memory was manufactured by Atmel and has a size of 512KB.
Its small specificity: it was developed to operate with a loss of voltage. We're on a portable console.

All the AT49BV040 flash memories that we have had in our hands have failed.
But SST compagnie a make a compatible flash memory which allows us to replace it with a reliable and functional series.
Manufactured by SST Electronic, it is called: SST39VF040 in TSOP32 format

3 - Repair the GP32

If you have made sure that the battery compartment is clean with no signs of oxidation and that your batteries are new, then you can begin to disassemble your GP32.
Here are photos showing all the parts of the GP32 once dismantled:

By turning over the motherboard of your GP32, you will discover the AT49BV040 flash memory which is faulty.

You need to remove the flash memory from your motherboard.
We strongly recommend that you use a hot air station to perform the operation.

Before marrying your new flash memory, we need to inject it with a bios.
We recommend that you install the GPBios bios. Thanks to the latter, you will be able to change bios without reflashing your console.

For more information on GPBios: http://spadework.utopia.free.fr/gpbios/

You will directly find the binary file ready to be written to your flash here:
