That's not long, and either way it's interesting! Not to mention awesome that MAME networking is getting some more love :)

My bro and I would play each other all the time at the local arcade (love hearing the "Check Point" ;D). Would be epic if someone could get Cruis'n USA/World working on MAME with LAN support. One day i'm sure someone will figure it out.

Long long description of how these games communicate from a pending MAME pull request.
"A two way link (Cruis'n USA, Radikal Bikers and Surf Planet) is self explanatory. Connect the RS-232 cable between both pcbs and set the correct network settings on both pcbs. A >2 way link (Speed Up, Cruis'n World, Off Road Challenge, Cruis'n Exotica and The Grid) requires the connected pcbs network IDs in numerical order and a pcb to have a network ID set to 1/Master. The reasoning behind this is each network ID can only communicate with the network ID numerically next to one another due to the serial port split into two; e.g. ID 1/Master controls ID 2, ID 2 is controlled by ID 1 but controls ID 3, ID 3 controlled by ID 2 but controls ID 4, and so on in a large serial circuit. Disconnecting anything connected to ID 1/Master will unlink all the slave pcbs while disconnecting a slave ID pcb will unlink any pcbs that aren't connected to ID 1/Master.
I just discovered a lot of Konami games use that same procedure. The difference between the two is Konami has their rs232 connection altered to make use of a pin jack/LANC connector and wires most likely because of how compact they are.

Hey, that's progress. Hopefully one day someone could get the Cruis'n Games to link up. Would be epic. Thanks for sharing.

Hm... Sadly it is not that simple, I tinkered around with a cruis'n'usa board a long time ago and never got it working. some said the pal might be bad, or the wiring was "wrong".
Software side wasn't better either, I could get them "startet" in link mode, but they would not communicate at all.
*EDIT*
most likely those games require some sort of sync that currently is not hooked up, much like the sega game sync up their v-syncs

The main control is from the main cpu TMS320C31's built in serial port (split into two) in addition to two pals, u111 and u38. It depends on the main cpu's address at 990000 seemingly controlled by the COMINT at pal u111. Pal u38 identifies what address 990000 is doing. It's possible the original Cruis'n USA u38 pal, A-19669 doesn't have the code which explains why the pcb won't communicate with that pal installed. Risugami has a lot to say about how these pcbs communicate and only had success by decreasing the main cpu's clock speed because the current clock speed is "too fast" for both machines to read the changes (most likely emulation bugs). Without any sync at the CPU level, it's not going to link. I am desperately trying to get Risugami to release his linking code for MAME so someone experienced or I can take a stab at what is going on. Does anyone know that person to see if he has other forum accounts or a discord because I can't find him anywhere.
It's a lot of sophisticated info for something simple (hence why I prefer the shared ram method used in a lot of Sega and Namco games).
EDIT: Do the Namco games sync up their v-syncs? I have been told V-Unit games sync up their v-syncs too but either that info isn't true or it's a much different method (which may explain the problems I have with linking Cruis'n USAs on two bad LCD monitors). In my situation, the slave machine will flicker a bit every few seconds and cut after a screen transition for a few seconds. The explanation behind this is those LCDs installed may think the signal/sync isn't acceptable so the monitor temporarily loses its signal as a result.

It's weird. Lately as i've been messing around a lot more with LAN/Networking games, i've been experiencing this internet error randomly "windows could not automatically detect this network's proxy settings." It's a ---smurfette--- to fix and I'm not sure what's causing it. Maybe I need to strengthen my malware protections? Just curious if anyone else who uses LAN often experiences this error. May be completely unrelated. Thanks
