Sega-Naomi

So question on this, no rush, I fired up Shikigami no Shiro II on my NAOMI setup at home, gives me an error saying the game isn't supported by my motherboard. It's got a Japanese G Rev 21576 BIOS in it, and ran GGXX:AC before I got it. I can't do too much experimentation, because all I've got is a Capcom I/O, and it doesn't power the motherboard and GDROM at the same time properly. All hints point to that my setup should run the game fine.



As for the Capcom I/O, I know I need some work there. I'm reading the other threads a bit too, but I'd like recommendations for the best setup. My cabinet is currently powered on an ATX power supply, and besides thru JAMMA from the I/O, there are no other power sources. Everything all together it's starting to seem like it's more trouble than it's worth.

wrong screen settings? report the error code so we can say for sure.



settings for the mobo should be screen set to vertical and 2P cab.

There's a vertical setting? I haven't seen that on any of the DIP charts online.



Aaand actually with a bit of fiddling, I got it to test menu. See what you mean about vertical there. We'll see, DJ Infinity suggested a newer rev. EEPROM, so I might pick that up, if anything eventually for Exzeal. Question, if I can get it to power sometimes by hotplugging the motherboard (i.e. turn on the cab, then plug power into mobo+GDROM) is that unsafe?

I had similar problems with various games. I was going through my stash of games to determine which ones were supported on US bios.



I got to V-NBA and got the "not compatible w/ main board message"



I know for sure my V-NBA will run on US BIOS.



This happened with a couple other games as well.



Not sure if there are some persistant setting being stored in ROM/RAM that would cause this to happen.



Like you, I finally got the various games working by cycling power and removing and reseating ROM board.



Not sure, but I think if you hold the test and service button on start up this causes some kind af hard reset.



Wish I know the exact sequence.



If you try to run a verticial game with cabinet set to horizontal you'll get a different message. Something like "gamecabinet settings incorrect" not the "not compatible w/ main board message"



I got the "not compatible w/ main board message" alot when I was swapping games around alot. Eventually they came up and ran. I wish I knew what the secret decoder ring was to keep this from happening???



(Because it is very frustrating when it does happen) :smt013

Yeah, appears like that problem is gone. Now I just need to deal with a new power supply, since every time it loads and goes to reset, I can't get it to power on again. Ah well, like everyone says, Capcom I/Os aren't as great as I thought.

Hot plugging is NOT a good idea

Yeah, besides the plug and play aspect of it as far as the kick harness and RCA connectors, I find it actually more limiting than the Sega Rev.B I/O adapter!

Unless its error code 02 it's probably the rom or dimm board not connected correctly. Push harder
