It’s…a lot, lol. I am on the home stretch of refurbing my Naomi Universal Cab, and have had a Naomi NetDimm setup for a number of years now.
Here are the pros and cons of owning one:
-Amazing library (arcade wise, only second to MVS or CPS2)
-Cart (and disc)-based games make arcade “board” collecting easy and fun
-Works well with HD displays as it can natively output 640x480
-You can use a modified PC PSU with it.
-Net bootable games with a Rasp Pi or even your smartphone!
-Many games can be played with a Dreamcast controller, and support the VMU
-Most of the Naomi library was already ported to the Dreamcast in fine form.
-Requires a lot of parts to set up.
-Often will require two PSU units to run, and is very temperamental at that.
-While Naomi mainboards are cheap, all of the other stuff needed (JVS I/O, PSU, etc.) adds up fast
-Games that require specific hardware (inputs) are largely unplayable do to such requirements.
I have traversed through all of the rings of Naomi-setup Hell and come out the other side, so feel free to reach out with any questions!
If you do want to go down this path, look for a ‘Capcom JVS I/O’ It will make your life a lot easier, to begin with.
It has a built-in sound amp, provides the necessary 3.3 volts, and can be powered via the JAMMA edge with a regular switchable arcade PSU. (And if any of this doesn’t make sense to you right now, if you continue on–it will! Lol)
