Skate323k137's NAOMI / Supergun project thread

[skate323k137]

I work at a web hosting company, so we're all pretty technically oriented folks there. Most of my co-workers definitely appreciate, if not envy, the setup. It was totally worth the several days of work (not to mention at least a weeks pay), especially when I finished up the sticks and everything worked perfectly.

I got some self-adhesive lamination today and put a top sheet on the sticks to really seal them up. Luckily I made it easy to drop out the buttons/microswitches, I mainly did that in case I need to "re-map" the buttons for different games. It's fine for six button fighters, but for games which only use 2 or 3 buttons I'll likely want to move the switches around; hence the separate ground wires to all the buttons.

Very nice! I'm imagining multiple boards that can be switched in, maybe unreleased Dreamcast games such as Airline Pilots or that Safari game?

thanks!

Yes, the NAOMI board is a cartridge system. There is a GD-ROM addon to support more games as well.

This list has it split by cart/gd-rom.

(sega-naomi.com is an excellent resource)

Apparantly, the airline pilot game uses 3 displays and 4 linked motherboards (!). The NAOMI is quite interesting, technically 16 of them could be linked together.

Carts I'm after and/or will eventually buy include Capcom Vs SNK, DOA2, the Power Stone games (I could technically wire 4 players for powerstone 2, if I can find an extra capcom kick harness), and If I can find them for a good price, zero gunner 2 and gigawing 2. If I ever get a gd-rom addon there's several more shmups/fighters I would most certainly want to seek out.

I'm very envious.

I will be certainly be doing something like this when I finally get real career and some actual money.

very impressive, and also very clean!

I wonder though, what was your inspiration for that button layout? Looks really far apart. More so than on an Egret panel even.

[skate323k137]

I've got big hands. I did intend the bottom row of buttons to be a little closer to the top row, but the curve makes it ergonomical enough. I usually use my thumb for the bottom row anyway, so it works out. I could easily drill out a new top sheet for one of the sticks and swap it in, it's just held in by four screws from the side.

I intend on making console adapters for the sticks by padhacking controllers to my same db15 pinout, at which time I could convert some of my other arcade sticks to work with the NAOMI and said adapters.

This is about as "clean" as it gets, as far as NAOMI setups anyway. Mobo, PSU, capcom I/O is pretty much bare minimum, and an ideal cartridge setup. I'd have to swap out or add another power supply for a GD-ROM add-on.

I also want to get a japanese BIOS eventually, but since the main NAOMI 1 motherboards are only like 70 bucks now (from the right sources) I may just get another one of those with a J bios rather than switch out the socketed EPROM bios. All I'd have to do is swap the power plug and USB cable to the other NAOMI.

[skate323k137]

Upgraded my bios to the latest japanese bios, and scored a network DIMM. Since emulation is cool to talk about on this board, hopefully this is too.

Basically, the DIMM board that stores the info read from a GD rom can be network booted, with the game image sent over a network. I can send makaron .dat rom's over my network at home, and play pretty much any NAOMI GD-ROM game now

I had to add a second power supply, the DIMM board was drawing too much power for the poor capcom I/O to put up with it.

That being said, I give you Ikaruga, on it's native hardware

This is fricken' AWESOME!!!!!!

I've heard of that, it would be sweet to have the whole GD-ROM library on a menu. Put a laptop in the Versus cab, have it all self contained. I have two Naomi's on the "E" BIOS so no network for me. It's on my to-do list of cab work though.

[skate323k137]

That would be awesome to have it in a cab. I'm waiting on my roommate to move out before I have room for any cabinets. I had to wait 6 months to get a good deal on a net dimm. people seem to want $200 or more for them, I snagged one for $90 on ebay as a buy-it-now.

I got the latest J bios (H) for $25 shipped, the guy on ebay selling them is very reliable. He also does re-programs for like $10.
