I'm not sure what to make of the green lettering on this version.

Note how the rock obstacles in radradj are drawn compared to radrad.
The US set properly masks the fill color, whereas the Japan set lets the color bleed out into the full tile.

The green lettering is them getting the video connector pinout wrong - look closely and they've got RBG on 123 instead of RGB.

DAC sound pitch is fixed here:
https://github.com/mamedev/mame/commit/e441312d775cd66eb29a6690d2f2b4ceb273b6b8
The schematics say that Z80 and MCU clocks are from "EXTAL", but does not say which XTAL. At least it means it's not the 18.432 video XTAL.

The green background on title logo is also fixed.
The green road on the 1st level in that video, who knows, maybe a different color prom.

Nope I've read the schematics the wrong way around.
CKP1(3.072MHz) goes to a latch, that goes to both Z80 and MCU clock input.

And I see that MCU MR (Memory Ready) pin is active when MCU reads/writes from 8000-ffff (the shared rom/ram with maincpu). So this a better fix: https://github.com/mamedev/mame/commit/9aa8a793f977166396c5b51a3e413abb98e10eda
