Which is the best I/O?

everyone recommends a separate PSU directly to Naomi. If you are using the power adapter from the Blastcity maybe your Naomi 2 is not getting enough power. The Capcom I/O is what everyone recommends and I think that v2 is the preferred version but don't remember why or how to identify it.

Ayup Capcom NAOMI Converter98701 ver2.0 is what ya want to use
I have tried quite a few different ones and that is the one I found to work the best.
Also @SNK-NEO-GEO is correct .. or at least with the set ups I have done. Run a dedicated Sun power supply for the Naomi itself and run the I/O with the JAMMA harness. I am actually in process of putting together another set up for my Blast City. I will let ya know how the final configuration works out. I am in a holding pattern at the moment waiting on a few bios' to be shipped to me. I however have two other NetBoot rigs up and running .. one being my Atomiswave project https://www.arcade-projects.com/forums/index.php?threads/us-atomiswave-set-of-cabs.6702/ where I actually showed testing and setting up the I/Os and what finally let me be able to actually run every game.

My plan, for the one I am putting into my Blast, is to use the -001 loom to power the JVS and the Sun PSU to power the Naomi 1. The Naomis are VERY picky when it comes to power.
The 120v for the additional power supply is coming right off the 120v for the cabinet using a connector I got from @Lemony Vengeance

The answer to this question depends on what you intend to play.
@SNK-NEO-GEO and @Dreygor I don't believe power is his issue, as he mentioned he has the Naomi connected to the Blast PSU NOT the Capcom IO (aka he is only using it as a JVS IO).
He also mentioned some games boot and some do not... Again if this was really a power issue nothing would be booting, or it would have some randomness to it (sometimes X boots and sometimes it crashes).
@tonyt76 when you say...
Do you mean you get a screen that looks something like this?

I only want to play joystick games, no gun games or driving games. For example 18 Wheeler and Metal Slug 6 do not load. I see a black screen after verifying memory and then nothing...The answer to this question depends on what you intend to play.

Well 18 Wheeler is a driving game, so you saying "I only want to play joystick games" then following it up with that title is a little strange. 
Metal Slug 6 is officially an Atomiswave game that was converted to run on Naomi by Darksoft... But these releases only seem to work on Naomi 1 (not 2 sorry).
You can see Metal Slug 6 Naomi conversion with violence patch applied running on my Vewlix Diamond + Naomi 1 (stock Taito JVS) here...

You are correct, but actually I was just loading a bunch of games to see how many would or would not load, and 18 Wheeler was one that would not load.Well 18 Wheeler is a driving game, so you saying "I only want to play joystick games" then following it up with that title is a little strange.

Right, that needs an analog supporting JVS IO... Typically not the kind of IO you would find inside a Blast City.
I guess you could have a special Sega panel made up, or maybe the Naomi Universal driving panel fits onto a Blast?
It would be rather unusual looking I think.
MS6 tho has nothing to do with the IO and everything to do with the Naomi 2.
I'd be willing to be that NO Atomiswave ported games will boot on it, but as I don't own one I can't test that.

Yep. I got it running all the stick and button games from Atomiswave, Naomi 1 and Naomi 2.

Who was it that couldn't boot the Atomiswave ports on Naomi 2?
@Dreygor I thought you had mentioned that at one point?
Did they not work at first then you changed something to make them work?
Yea I found the post you made...

From that same thread @Derick2k was saying he had the same black screen issue with Naomi 2.
I'm pretty sure all of my Atomiswave roms end in .bin on the sd card but I will check this evening.

Yeah I swapped to the Naomi 2 with a Capcom I/O v2 and everything started working. The Atomiswave games had some kind of weird check going on that was stalling out, but I don't have any issues now.
However moving forward I am not going to be using the Raspberry Pi netbooting with the set up going into my Blast City. I will be using the Orange Pi style being developed by @Finisterre and @fsckewe which basically lets you use a USB stick as a compact flash. Boots right into the game .. no tinkering around.

As they should... I wasn't suggesting that was the fix... Only that @Dreygor had the issue in the past.
I've never owned a Naomi 2, so I only know what I've seen posted.
You are NOT the first person who has reported that black screen issue, but I've never been able to replicate it on Naomi 1 (so I think it only affects 2 but IDK).
Oh so it IS IO related after all?
So strange that the V2 Capcom IO works but the V1 IO won't (I really didn't think they had a functional difference).
Did you have to rename all of your Atomiswave games to .dat?
The Recommend IO for a Blast City is the Sega JVS to JAMMA IO. Sega even made an official JVS Loom for this IO with the proper power connectors for NAOMI.
I don't know why anyone is recommending you buy a SUN PSU for a Blast since the Blast's PSU is already better than the NAOMI SUN PSUs and supply the proper 3.3V
Here is the manual for the official Sega Blast City JVS Kit which includes the above IO along with the appropriate harness (literally the only two things you need): https://wiki.arcadeotaku.com/images/9/97/SEGA_cabinet_JVS_conversion_manual_.pdf
The reason the Capcom IO doesn't work for some games is that it doesn't support outputs (ie: lamps) and a number of NAOMI games will not boot unless the IO supports this.
