Not only that, but the other colours look bad too, look at the larger picture in the other report: http://www.mametesters.org/view.php?id=3102 (ignore the red enemies). The sea is about 20% green 80% blue, as opposed to 100% blue in MAME, and the land border is more defined.

Any resistor networks between the PROM/video chip and the connector on the PCB? -- I've hardly any knowledge on resnets myself though.

Oh, and could a PCB owner measure the clock speeds? It might fix (or at least help) the completely off-tune music, current clocks:

MDRV_CPU_ADD("maincpu", M6809,XTAL_18_432MHz/6) /* ??? */ (3mhz)
MDRV_CPU_ADD("audiocpu", I8039,XTAL_18_432MHz/2) /* 9.216MHz clkin ?? */
MDRV_SOUND_ADD("snsnd", SN76489A, XTAL_18_432MHz/12) (1.5mhz)

I measured the clocks, plugging these into MAME results in ... bad sounds. There must be something else going on.

76489 - 651ns - 18.432 / 12
6809 - 651ns - 18.432 / 12
8039 - 162ns - 18.432 / 3

Additionally yes there are colour output resistors, interesting that MAME has a tint though since it looks like each colour has an identical set of resistors. Picture in MAME overall is dim and lacking vibrancy compared to the PCB, these are definitely involved.

have you verified the PROMs? in other cases where we've seen tints like this when the resistor levels are all the same it's ended up being due to a badly read prom with a floating bit.

I'll see if I can get hold of a second PCB from somewhere, dead or alive, and desolder them - not really feeling like pulling them out of this one at the moment. Luckily it's a cheap game.

Can "sound incorrect" removed from the title summary? --> 03108: finalizr: White colour appear purple / sound incorrect

Added sound mcu internal rom (0.241):

the sound now is 80 to 90% fixed, only need fix the pitch for bgm only, maybe for the next update the sound is fixed to 100%
Color maybe need more data and better screenshot (need more screens)

PS: exist a set with the life bar down (this maybe is possible with old set or bootleg set)

Music pitch sounds same as the PCB to me:
