Thanks, not to mention if you disable the traffic, the AI cars are random generated, I think it's probably due to the bad chip thing that causes the game to freeze.

I'm unable to reproduce this in this in the latest version of mame. It could have been a CPU or DSP core bug but idk which version fixed this. Tried it on both standard and time attack modes.

Never seen that one, because ZR107 hardware doesn't run like normal in newest build.

This doesn't seem fixed in my testing of current Git. It is possible it is based on the car chosen, but I'm not sure.

@Tafoid, I found what causes the bug. It happens if the pcb network ID is set to any ID but 1. In previous mame versions, the network ID DIPs were incorrect/reversed (network ID 1 in previous versions were actually ID 4) so that may have been why this bug was submitted. I'm now starting to think this may be a 'BTANB' for multiple reasons. Konami probably intended on having unlinked Winding Heat have their ID set to 1 because of their possibly buggy network code. A pcb that has their ID set to any ID but 1 probably expects one or more machines to be connected. Because there are currently no other machines in the network, it may cause some glitches.

Someone with a Winding Heat pcb needs to verify this (along with its network test which has the cursor jitter when it isn't supposed to).

Network related. This behavior no longer happens regardless of network ID.
