Notes on how I got Ringout working on my driving cab.

[Finisterre]

I was trying to get RingOut to netboot, and I got an error about needing two IO boards. How can I make this happen? I have a few spares.
"Two jamma I/O boards are required for this game" is what I am seeing.



I tried to wire the secondary card to the 5V Power out, on my first card, and then used the secondary USB port on the first to connect to the second card, but then I got nothing for either card inside the JVS test when I did that. I recall 12v is only for lighting effects, so it is not needed.

Looks like I can boot RingOut now! It turns out that my original attempt was thwarted by a bad USB cable. Upon a second try things worked as expected, and I had two JVS nodes in the test menu. I was able to successfully daisy-chain the power from CN8 on the first board to CN7 on the secondary board.

I create the image with the following instructions.

1. Download a mame image of Ringout
2. Concatenate the mame image into a netboot image by combining the *.ic* files in the proper fashion
$ pwd
/Downloads/ringout
$ ls
mpr-21770.ic2 mpr-21773.ic5 mpr-21776.ic8 ringout-key.bin
epr-21779.ic22 mpr-21771.ic3 mpr-21774.ic6 mpr-21777.ic9
mpr-21769.ic1 mpr-21772.ic4 mpr-21775.ic7 mpr-21778.ic10
$ cat epr-21779.ic22 > game.bin
$ dd if=/dev/zero bs=1 count=$((0x400000)) >> RingOut.bin
$ cat mpr-217* >> RingOut.bin

3. Push the game as you normally would
# ./netboot_upload_tool 192.168.1.95 10703 RingOut.bin

Here are some pictures of Ringout running on my 18 Wheeler cabinet, I'll update further as I get it playable. It was previously freezing when I coin up, but this appears to be tied to some region issues. I moved my Multi-BIOS to USA and it stopped locking up, and the attract mode actually works properly.
