Cruis n usa and Cruis n World (MAME) link 2 players?

[lirogames]

hello everyone, I searched here in the group, and I didn't find anything, I would like to know if it is possible to play these beautiful games in a link, both on the same pc and via lan .. ..

IIRC it's not working. There's some more info in this thread - http://forum.arcadecontrols.com/index.php/topic,161667.0/all.html

In Cruis n World I can't put it in manual shift. No choice option appears. The game starts directly on automatic. I already tried to solve it in the test menu but there is no option for that. Can someone help me?

The above info is no longer true. Someone else opened an issue in Mame regarding networking on this family of hardware (in reality it's a CPU mailbox bridged together similar to the Naomi multiboard system). There's even worse problems for other games that do not support LAN.

midvunit.cpp linking (Cruis'n World, Cruis'n USA): https://github.com/mamedev/mame/issues/9958

Bus network topology support: https://github.com/mamedev/mame/issues/9101

You can view a list of all the unsupported LAN capable games I listed here: https://github.com/Hydreigon223/mame/wiki/Arcade-Networking-QA

In Cruis n World I can't put it in manual shift. No choice option appears. The game starts directly on automatic. I already tried to solve it in the test menu but there is no option for that. Can someone help me?

Use Cruis'n World v2.4 instead of v2.5 because the latter was developed as a conversion kit for Hyperdrive arcade cabinets. Midway programmed this version to skip the transmission select due to Hyperdrive cabs not having a shifter to begin with.

Hydreigon, thank you very much!

I don’t have a manual option in my Crusn World so I will have to check that out.

I added custom race leader code to Crusn USA and Cruis’n World. As soon as these are linkable I will make sure the code works for two (or 4 for World) players. I will post the code tomorrow in case anyone else wants to do this for games that don’t support it back in the day.

Just in case a Mame developer or people working on Crusn link mode see this forum post, I noticed that the dip switch settings in the Mame tab menu show question marks for the dip switch related to link lan mode. I looked at the manual and the dip switch 6 is the link lan mode and dip switch 7 is not used even though Mame acts like it may be a lan option. Dip switch 8 is the master/slave switch though.

It looks like someone started to get Crusn USA Mame linked. It’s a work in progress but that is great news. This and the R San Francisco Rush project is awesome. I wonder if gpt5 will help when it comes out help speed up the development time on linking these.

Well...


The best way I can describe how that link works is "crazy".
Still need to find a proper way to "frame sync" the thing =)

[SailorSat]

consider it "done".
all that is left on that one is offroad champions.

Holy crap! this is amazing! thank you!  Are you going to release a fork of mame or submit the changes to the mame devs?

[SailorSat]

probably both as my current pull requests are in limbo for like half a year now...

also i don't think that the proof-of-concept implementation is of the required "quality" to fit in baseline mame
currently working on getting offroad challenge working... for whatever reason every single v-unit game uses a different protocol 

[SailorSat]

probably both - my latest pull requests are still not merged after half a year.

currently working on offroad challenge.
every v-unit game implements its own protocol, although I can see the logical progression with it .)

WHAT!? This is awesome thanks so much SailorSat! This is a holy grail for me. Is this working well enough to go ahead and put on my 4 player cabinet build you think? We just need to wait for the Mame build and then change the cabinet ids like in the video?
