No I haven't but Phil Bennett fixed the road colour issue as he thank me for pointing it out.
Just wanted to let any MAME developers know that there is another TX-1 version not in MAME yet. The version is very like TX-1 (World) but on the middle screen it says TAZMI® TX-1 instead of ATARI® TX-1.
You look under "Then one must take it back a notch to playing the three-screen marvel, TX-1" & "Gotta get pole position!" you will see the same title screen as it is.
