Feature 1 Optical Drive Simulation Board: for GDEMU optical drive simulation board, with for GDEMU's expansion storage memory card holder, replacing the CD ROM drive enclosure. Fast game reading speed and smooth game process with replacement memory card holder. 2 Heat Dissipation: for SEGA Dreamcast console optical drive board with all metal card holder with two heat sinks, effectively improve ventilation and heat dissipation, read memory cards more smoothly, stable and wear resistant. 3 Compatible: This for GDEMU optical drive emulation board is suitable for SEGA DreamCast console VA1 version console (for GDEMU expansion adapter). High and stable performance ensures you enjoy your games. Perfectly runs the original version as a GDI image and is compatible as a CDI image. 4 Easy to Install: Game machine drive simulation board is easy to install, you can remove the original optical drive holder and replace it with for GDEMU, no soldering and no modification to the machine board. No harm to the host. 5 Perfect Replacement: The for GDEMU is a replacement for the memory card based optical drive in the for Dreamcast mainframe. for GD ROM, for CD ROM drives will inevitably wear out and fail (as all mechanical devices do).Item Type: for GDEMU Optical Drive Simulation BoardMaterial: ABS, PCBColor: WhiteHeight of Analog Board Holder Interface: Approx. 8mm/0.31inVersion of for GDEMU: V5.15bApplicable Products: for DreamCast VA1 Game Console (for GDEMU Expansion Adapter) for GDEMU V5.5, for GDEMU V5.15 and for GDEMU5.15BUpgrade: Changed Storage Card Holder, Full Metal Card Clip, Read Storage Card More Smoothly and Stable.Features1.

Please allow some errors due to manual measurement.2. You can install dc host for VA1 motherboard, otherwise it will burn gdemu! Remember not to plug and unplug for GDEMU with power on, must be careful.3. Since the console is no longer in production, it is almost impossible to provide spare parts. There is no active component to this project, so it is intended to provide a "one and done" solution.
