This works if someone would like to test..

static VIDEO_UPDATE( spaceint )
{
const UINT8 *color_prom = memory_region(screen->machine, "proms");
int offs;
UINT8 data,color,y,x,c;
offs_t n;

if (screen_flip)
{
for (offs = 0; offs < videoram_size; offs++)
{
data = videoram[offs];
c = colorram[offs];
y = offs;
x = ~offs >> 8 << 3;

/* this is almost certainly wrong */
n = ((offs >> 5) & 0xf0) | c;
color = (color_prom[n]);

plot_byte(bitmap, y, x, data, color);
}
}
else
{
for (offs = 0; offs < videoram_size; offs++)
{
data = videoram[offs];
c = colorram[offs];
y = ~offs;
x = offs >> 8 << 3;

/* this is almost certainly wrong */
n = ((~offs >> 5) & 0xf0) | c;
color = (color_prom[n]);

plot_byte(bitmap, y, x, data, color);
}
}

return 0;
}
