SOLUTION: Long story short, 18 wheeler needs an original bios and does not work with the multibios
Hadnt played the game in a few months but worked fine previously. Turned the cabinet on everything seems normal at first; I choose the driver, goes the the USA map screen, then goes to the truck idling screen, then back to the map screen where the cities light up, gets to Florida but just seems to lock up there and you still hear the engine idling noise. Tried a different Naomi system that gave me an Error 1 so tried my Naomi 2 and it does the same thing as the first system. I try my Netdimm with the original Naomi 1 system and it doesnt boot up. I try the second Naomi 1 which I tested separately with the netdimm and worked fine but plugged in to the cab it doesnt boot up. I tried the Naomi 2 with the netdimm it does boot up loads the game (gives me motor error which was odd) and it locks up in the same place as when I have the cartridge in there. So I try net booting Crazy Taxi and although hard to play it works. Tried one of the SNK vs Capcom and started a game and it worked fine also, not that I could do anything other than punch
Other things I tried, tested voltage on power supply at the system connection and it was fine, tried a second working power supply also. Swapped I/O boards and same thing.
This is driving me bonkers, any guesses what is going on?
Thanks!!
