the black background is a wire hack to the pcb, causing the prom halves to be inverted, or forced to one or the other.

the correct way it was shipped was with a blue background, as it is in MAME.

(just as many nibbler boards don't have music because the music rom was removeed etc.)

This has been confirmed by people who own the PCB in the past, the new video doesn't prove anything.

Wow you make it sound like I have NO idea what I'm talking about! Okay Haze have it YOUR way. I am happy with MAME either way, so thanks. I give up testing.

In the movie Rocky III (USA 1982) goes Burt Young thru an arcade hall and
you can see here Astro Fighter with a blue background (see Rocky3-3.jpg).
I don't think it's black, they like it blue in the 80s... Thats all :)

Indeed, this 'war' on Mame having a blue background in Astro Fighter is pointless.

As things stand, we have evidence from the PCB, that without a wiremod / hacked PROM the background is blue. If you want to turn it into drama and quit the scene over it, that's your problem.

If an unmodified PCB, using the same PROM as MAME, with original labels on all parts, and clearly no replaced parts shows up, and has a black background, the situation will be reevaluated. (and that will mean it being in a position where it can be tested, not just an auction on ebay)

Given that people also report the game had an English title screen, and all the sets in MAME only have the Japanese one it's possible there are undumped versions.

While I don't have an original reference for this next example, other games of the period, such as Space Attack also have a blue background, despite being on completely different hardware.

It is also possible that they decided at the factory that there had been an error in production, and installed the PCB mod before shipping it, that will be difficult to prove.

Yes, it's true that for Super Astro Fighter they clearly have Black during gameplay, with Blue for the refuel background, but again, it's not evidence as they may have just seen that it was more popular that way.

Note, that if you apply the same colour prom inversion in other games of the driver Tomahawk 777 and Space Fighter Mark II go from having black backgrounds, to having blue ones. In the case of Tomahawk you could argue that makes sense, because it's 'underwater' but even the space area of that becomes blue too.

Given that it's a known PCB hack, a driver configuration switch to invert PROM access could probably be added.

Note, I've attached a diff which documents the PCB hack in the form of a DRIVER CONFIGURATION switch. ( File Added: )

(ignore the first file, i attached the wrong diff)

I would say that a CONFSETTING is the best solution. Shall I go on, and commit it, Haze?

the alt tomahawk colours shown in a messageboard thread are the result of using the Astro Fighter PROM with Tomahawk btw. I doubt that was an official configuration, more likely the result of a board conversion in which the colour PROM wasn't replaced.

If you use the inversion trick, the only difference in Tomahawk is that the background changes from Black to Blue, the other colours aren't affected. For the older set, it swaps the sky/sea black and blue around.

Quite why the 'older' set makes better use of the hardware I do not know.
