Graphic glitch in Space Demon by Fortrek

I know the colors are off, but is it possible to have the background color fixed? It's supposed to stay a black background with the stars coming down but as soon as the game gives you control of your man after starting, the background color turns blue.
Thanks for fixing Burgertime in cocktail mode and Donkey Kong 3's graphic glitch... Working great now

I'm bumping this thread. I suspect that there's a bad rom dump of SDM E-20 (from the ESS board). It's a 2708 eprom, and removing it makes the 'blue screen' issue go away.
Is there anyone out there with a known working Space Demon board set that can loan out the rom chip from their ESS board to see if the rom contents match what's been used in the MAME files?

On the Space Demon boardsets from fortrek the Ess Sound board layout has extra components and an extra 74LS74 chip than the Nintendo Space firebird Ess boardset. I have verified both sets of Mame roms from an original Space Demon boardset made by Fortrek and space firebird roms set including the bi polar proms and all the roms verify the same in winromident with the same checksums.I believe it is the additional components on the ESS board that is causing the blue background issue as the video board works in conjunction with the ESS board. I have taken some pictures of the areas on an original fortek space demon boardset that are different than the space firebird.Having schematics would help for the original space demon ess boardset. One other difference too is a 10k resistor is replace by a 20k resistor and is printed on the board itself.

Roms are identical I had to make an adapter to read the 2708 Eprom but the checksums are identical to the dump in MAME.

If you don't see it in the whatsnew file or the SVN monitor it isn't happening.

Bumping this again. Is there no one that's willing to take on the ESS board driver info? This shouldn't be too difficult to do, compared to some of the other stuff that the devs have tackled....

LOL! No matter how many times you ask, it'll get done when the devs decide to do it. There are A LOT of bugs that the devs constantly work on & trying to get new games to work. Heck, there are a few games I can't wait to see fixed. When someone has any interest, they'll work on it. But bugging them is a good way to make sure they won't work on it

Maybe you should be looking for a good programmer who can fix it, since MAME is an open project and nobody seems to be working on it currently.

I get rid of blue screen in games like this and Super Cobra, Gorf etc by turning down gamma and adjusting contrast. For this game I just reduced gamma to 0.100. Unfortunately this work around erases the background stars.

In the 8 years now you've been asking the devs to fix this you could have learned enough to have fixed it yourself.

Dude, I know you just ignore what everyone says, but if you keep it up you're likely to get banned, and you're assuring that no dev is going to want to work on it just to spite you. They don't like being nagged and all you're doing is pissing people off
