The Dreamtray is an extension for your GDEMU. The fits into the housing of your old GDROM on the upper shell of your Dreamcast It is equipped with an extension cable and an SD connector to be able to deport the insertion of your SD card. It is also equipped with two buttons which manage the GDI and CDI images installed in your SD card.
Why the DreamTray?
Like many peuple, we have try GDEMU type ODE (original or clone ...).
We have show some small flaws with our GDEMU:
The Dreamcast remains with a gaping hole in place of the GDROM following the installation of the GDMEU.
When we inserting / removing the SD card, we request the SD card connector of the GDEMU (very fragile plastic connector on some version)
When inserting / removing the SD card, we request the SD card connector of the GDEMU (very fragile plastic connector on some version)
The SD card can slip from our fingers and fall into the console
The GDEMU is only mounted on GDROM connector, the GDROM connector of the motherboard is mechanically stressed each time the SD card is inserted / removed.
The management of the change of disc is limited to one button
Ventilation problem due to the absence of the GDROM reader. The ventilation system developed by Sega is no longer effective due to the hole left by the absence of the GDROM. The DreamTray will obstruct the gaping hole left by the absence of your GD-ROM, which will allow your console to recover its nominal ventilation system.
Power supply temperature rise problem due to the lack of load on the power rail of the GDROM drive motors (Edit: Solution available here : GDEMU Power Supply Mod) There are solutions in 3D printing, but the quality is disappointing, the end result is not good quality.

How to assemble and install the DreamTray?
The assembly and installation of the DreamTray remains very affordable if you have already handled a soldering iron. A video tutorial is available on youtube:
How to test your UP & DOWN buttons on your DreamTray ?
It is important to know that the buttons are active, but that the GDMENU software does not take into account the commands of the UP and DOWN buttons in real time, in the same way as the original button present on your GDEMU. To test your buttons in real time, you have to do it from the "Music" menu of the Dreamcast bios.
To do this, from GDMENU press the Y button on your controller
GDMENU will ask you this : "EXIT TO SYSTEM MENU ?" Confirmed by "YES"
Back into the bios, go to "MUSIC" menu You now have real time feedback to test your UP & DOWN buttons from the "music" menu. You will see your different GDI and CDI images disc scrolling
Obviously, the buttons are 100% active during your games, otherwise there would be no interest
The Net Yaroze is a development kit for PlayStation released in 1996.
Aimed at amateur developers, it was first marketed in Japan, then in Europe and the United States for a price of $ 750.
Similar to its big sister PlayStation, the Net Yaroze touches a matte black dress with a different texture.
It has an additional function compared to the standard PlayStation which allows to test Homemade games created directly on the PC thanks to the software delivered with the kit net yaroze (DTL-S3030 for the Japanese version and DTL-S3035 for the US version or PAL ).
The Net Yaroze has the ability to play Japanese games (NTSC-J), American games (NTSC-U), European games (PAL) and another additional format that we will see below.
To test your achievements, a transfer of data from the PC to the Net Yaroze is necessary, it is at this time that the hardware part of the Net Yaroze takes all its importance.
The Net Yaroze Kit includes a serial link cable (DTL-H3050), a "Access Card" dongle externally identical to a black color memory card (DTL-H3020), and a bootable CD that enables communication between the device. PC and the Net Yaroze.
The Kit also includes operating and reference manuals (DTL-D3060, DTL-D3070 and DTL-D3090) as well as two machine-matched joysticks (DTL-H3010).
The Net Yaroze is released under three different references:
DTL-H3000 : Japanese Yaroze Net Console (NTSC-J), 110V Power Supply
DTL-H3001 : American Net Yaroze Console (NTSC-U), 110V Power Supply
DTL-H3002 : European and Australian Net Yaroze Console (PAL), 230V power supply
The Net Yaroze kit includes:
DTL-H3000 (JAP), DTL-H3001 (US) or DTL-H3002 (PAL): "Net Yaroze" system (Black Playsation) DTL-H3010: Two PlayStation black game controllers matt DTL-H3020: "Access Card" black DTL-S3030 (JAP) or DTL-S3035 (US and PAL): Boot CD for Net Yaroze DTL-S3040 (JAP) or DTL-S3045 (US and PAL): A development CD for PC CD-ROM (SDK) DTL-H3050 -> Communication Cable DTL-D3060 -> Start Up Guide DTL-D3070 -> User's Guide DTL-D3090 -> Library Reference
Net Yaroze VS PlayStation
Net Yaroze and PlayStation are different in color and texture.
Net Yaroze is black with a slightly rough coating against the PlayStation which is gray with a rather smooth coating.
The Net Yaroze is free zone, it allows to read all the strange games when the PlayStation is zoned by region (NTSC-J, NTSC-U or PAL).
To have the best comparison possible, we compared a Net Yaroze to a PlayStation released at the same time (there have been many versions of PlayStation), so we named the PlayStation first revision of the PlayStation: the SCPH-1002.
Both consoles share the same motherboard: the PU-8, but some components are different.
The component that differentiates the Net Yaroze from the PlayStaion is the MECHACON (Mechanism Control).
Against all received ideas, the bios is not specific to the console Net Yaroze ! It's identical to a classic PlayStation!
For the rest, the Net Yaroze is identical to a Playstation SCPH-1002 (Power supply, optical block ...)
Boot CD Net Yaroze and MechaCon
In order to communicate with our PC, the net Yaroze needs to switch to communication mode and must be able to execute code coming from the PC.
For this Boot CD Net Yaroze is essential.
DTL-S3035 US ou PAL version
DTL-S3030 Japanese version
But why not use the Net Yaroze cd boot in a PlayStation?
Because the Boot Net Yaroze CD does not work on a standard PlayStation!
A little explanation about the safety of PlayStation discs is needed:
A PlayStation is zoned in its geographic area and this region code is stored in the Mechcon:
SCEI = Sony Interactive Entertainment Inc. = JAP Playstation Console
SCEA = Sony Interactive Entertainment America = Playstation USA console
SCEE = Sony Interactive Entertainment Europe = PlayStation Console EUR
A Net Yaroze is rezoned and has an additional xode region, it takes into account all the regions of the world plus a specific region to Net Yaroze:
SCEI = Sony Interactive Entertainment Inc. = JAP Region
SCEA = Sony Interactive Entertainment America = Region USA
SCEE = Sony Interactive Entertainment Europe = Region EUR
SCEW = Sony Interactive Entertainment World = Net Yaroze Region
On each PlayStation CD, the region code is written on a portion of the CD that only the PlayStation or Net Yaroze is able to play (which makes it impossible to copy a PlayStation disc). Net Yaroze does not play CD-R or Backup type burned games.
Depending on the type of Mechacon the console will accept the CD or not.
The Boot CD of the Net Yaroze has a region code " SCEW ", so there is only Net Yaroze who can read it!
Dongle "ACCESS CARD"
Sony has created a security dongle that locks the use of Boot Net Yaroze CD: "Access card"
This is the second security of the Net Yaroze. Because of the modchip or CHIP available on the market, Sony has locked the Boot Net Yaroze CD to avoid being hacked.
The dongle is placed in slot memory card 1, when the boot CD, it will check if the dongle is present.
If the net access card yaroze is present the program of the boot CD activates communication with the PC, otherwise it ends the program!
The serial communication cable "DTL-H3050"
To communicate with the PC, the Net Yaroze uses a connection close to the RS232 communication. the difference is just a reversal of logical levels and a different voltage level. In order to communicate, we must therefore use a reference communication cable "DTL-H3050".
It connects to the "Serial" port of the Net Yaroze and to the serial port of the PC.
SDK Sony Net Yaroze
The SDK for developing your creations on Net Yaroze is included in the Net Yaroze kit (DTL-S3040 for the JAP version and DTL-S3045 for the US and PAL version).
Everything happens in DOS system, but with the software « SIOCONS » translate «Serial Input Output CoNnectionS » which loads a memory your program on your Net Yaroze.
