Which is the best I/O?

yep, we welcome all the donations made for games preserving! :)

sadly all "cool" games was preserved a long ago, and there left only "nobody cares" type of games, like mahjongs ;)
btw, not a long ago we got uber-rare one for NAOMI "Sega 4 Players Mahjong MJ"
perhaps @Gakman will be interested to put it in collection

Or maybe just create an easy printout guide for what games require what cab settings in the Naomi.
For Joystick games:

Vertical Games Require monitor to be set to vertical
Horizontal games require monitor to be set to horizontal
make sure cabinet type is set to 2 player


I'm not exactly sure what else you need?

I don't really care about the cab settings, I want to know what games demand what JVS IO features.
Super detailed shit like... Game A will run on Capcom IO Version 1 but not a Version 2.

Not to mention all the BS like... Game B only uses 6 buttons, but for no discernible reason demands the IO report 24 active buttons to boot.

For stuff in the Game A column, sure we don't really need a patch just the info about it.
For stuff in the Game B column, we need patches because that's f'n stupid!

Which is the best I/O board for a Naomi 2 in a Blast City? I am currently using the Capcom I/O but a lot of games do not boot.
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.
@twistedsymphony thank you this helps a lot!
 
So the plot thickens...

I turned the blast off to see if MS6 would boot up again. 6 tries in a row (failed)!

I am running a Multi-bios in my Naomi 2 with the bios currently set to USA.
 
have you check/adjusted your voltages?

Intermittent problems like that are usually indicative of a harness or power supply issue.

I have not done this yet. I have Lemony's JVS extension harness with the two volt meters on it, but i'm not sure how accurate they are compared to a good digital meter.

If anything the 3.3v and 5v were a little high. (like not 3.3 or 5 exactly)

That should be fine.

have you ever cleaned the connector between the NAOMI and the DIMM board? I've found this is a significant bottleneck for the power. and if it's not completely clean it can lead to games not booting and people needing to "reseat" the DIMM board often.

Also note, the NAOMI2 with a DIMM board can take up to 2 minutes to boot. I'm talking 2 minutes from power on until you see the NAOMI logo. so make sure you're not just giving up before it's finished booting.

I'm sure you've seen my compatibility chart: NAOMI Net-Boot BIOS and I/O Board Compatibility Chart

I went though nearly every NAOMI game with every JVS IO at my disposal

If you want to know which games might give you grief on the Taito IO due to lack of input look at the Sega JVS JAMMA IO column for "works**" that double star means that it needs the expansion header, meaning it expects 6 buttons per player.

From that the only 2 joystick games out of everything I tested that might give you issues are Gigawing 2 and CVS2.
In my testing Atomiswave games seem to have NO IO requirements at all, which makes sense because the Atomiswave doesn't use an IO board.

you're welcome to fill in the blanks, or add another column to the chart for the Taito JVS IO. Let me know and I'll give you write access.

At some point I'm going to go through them all again using original carts since I have a nearly complete collection of joystick games on cart now.

If you want the best compatibility though the Sega JVS Type 1 works with EVERY game in the NAOMI library except Sega Bass Fishing Deluxe.
 
Thanks T!
Yea I need to take a crack at Gigawing 2, I think it will be another patch for the Taito IO but I'll report back.

I did consider changing the IO in the Vewlix to the Sega, but I didn't want to hack up any wire harnesses and that official Taito 60pin adapter is (like everything else they sell) big $$$.

I also hate the idea of non-stock parts in my cabs.
Adapters for game boards I'm ok with, but swapping out OG parts of the original cab just dont sit right with me.

OK last night I ran a couple of experiments with the hardware I am planning on putting into the Blast. Basically it's the whole set up I plan on using but I borrowed the Bios' from one of my other rigs as I am waiting for the set for this to be delivered.

What I found is that using just the power from the power supply in the cab it would run all of the normal Naomi games .. however it would not run the Atomiswave games. But when I separated the power and used a separate power supply for the Naomi 1 it would run the Atomiswave games just fine. I did take a multi-meter and check all of the voltages from the cab's power supply and everything was nominal.

I swapped back and forth a few times with different games and got the same results.

Soooo I am going to go with the dual power supplies as it lets me play the Atomiswave games.

This is also using the Orange Pi solution, not that that should make a difference.

@Dreygor thanks for posting this! Can you post a picture of the top of your Sun power supply? I want to see if its the same one I purchased.
 
@twistedsymphony is it possible to use the Sega JVS Type 1 I/O in a Blast City? If so, do you know what I would need to hook it up?
you can use any IO board you want if you're willing to build a custom harness for it.

I wouldn't bother though, the Sega JVS to JAMMA IO I suggested earlier has nearly as good of compatibility, and requires little to no changes to the wiring.

What game do you want to play that your current IO board doesn't support?

AFAIK the only games that have issues with the Capcom IO are those that require output for lamps, which are mostly driving/sim games. The only digital control game I know that doesn't work is Virtual On since it requires lamp output.
 
@twistedsymphony on your spreadsheet, what does the Naomi 2 column mean on the Naomi 1 tab? That you also tested that same game on the Naomi 2?

Also, if the cells are white, does it mean that it didn't work, or you did not test that scenario?

it means a NAOMI1 game being played on NAOMI 2 hardware

For all columns the key is as follows:
white = untested
green = works
yellow = partially working
red = does not work
