I found a I/O pcb on eBay a few months ago, and after some really solid cleaning I got around to testing it on my Rev 2 mobo.

As far as the layout between a rev 1 and driving I/O boards are concerned, they appear to be identical. Seems like the bios is controlling the functions of the board itself, as my bios is marked with a D revision...which I am highly assuming is driving.

I don't have a Rev 1 I/O board to test my theory on, but my guess is if you bios swap the boards you can convert a fighting board to a driving and vise versa.

Now I just need to wire up a wheel and pedals. Unfortunately my I/O board came with no wiring, so I need to rebuild both harnesses into the board and then figure out what pins are what. I haven't found a schematic for the driving games yet so that'll be fun......

and I did boot past network check screen using the pinout ground diagram on Jamma Nation X. Glad that exists!

I found a Roads Edge schematic that might help http://crazykong.com/manuals/RoadsEdge.man.pdf last two pages

The problem with the schematic is it does not seem to tell you what pins go from the 34 and 32 pin connectors on the I/O board TO THE JST connectors. Considering I don’t even have the harnesses, I’ll have to figure it out some other way. I know a few people who have them so maybe someone will take copious photographs so I can do it visually. That’ll cost some real beer money though lol

I'd ask Xian Xi or NeoTurfMasta, seems like they have the most info on these HNG64's

Lukemorse1 has a video similar to what you're attempting

Yeah I have the pinout for where I have to install leads from the wheel / stick to the connectors on front of the I/O board. What I don’t have is a wire map from the JST housings to the two row surface mounted connectors on the I/O board. One 34 and one 32 pin connector. That’s what I don’t have a schematic for
