I did some more poking around (aimlessly), and if you put right under INT32 scrolly = ....:
        if (!type) {
            scrolly = ((*DrvScrolly)) & (0x7ff >> 2);
        }

You'll actually get a background in level3, but its not in sync. with the sprites.  It seems like things aren't being calculated properly in 4x8 mode.

Here's some pics, the first is fba w/that above codesnippet, and blacktiger level3 how its supposed to look. (clipped from yt)

Sure thing man.

Find this:
ofst = (sx & 0x0f) + ((sy & 0x0f) << 4) + ((sx & 0x30) << 4) + ((sy & 0x70) << 7);
make it this:
ofst = (sx & 0x0f) + ((sy & 0x0f) << 4) + ((sx & 0x30) << 4) + ((sy & 0x70) << 6);

Bug in search, sometimes it doesn't find everything.

For example. I type Mahou into the search box, and it brings up
Dimahoo
Great Mahou Daisakusen (clone of Dimahoo)
Sorcer Striker
Mahou Daisakusen (clone of Sorcer Striker)

(So whats the problem?) It didn't bring up:
Shippu Mahou Daisakusen / Kingdom Grandprix

ideas? looking at the code, it looks like everything is alright...

Vendetta - theres a lot of sprite priority issues, and clipping in the first boss-fight on the back of the truck.

The sprite priority issues start to happen around level 3, I think.  There's people that come out behind doors, but you see them before they come out.  Also, on the ship, there are scooba-divers that swim right through the ship.  I don't have images or states to back this up at this time, will try to get them in the next few days!

Clipping: see the attached pic (c.o. JacKc) - the left side of the truck is missing sometimes, happens at the first boss encounter:

PCEngine, rarely something will show up sort of off by a few pixels.  I think it has something to do with windowing, but, its just a guess :)

Violent Soldier / Sinistron (same game/different name) on PCEngine has what appears to be a similar problem, just start the game and play for a few seconds, you'll see what I mean.  In the below picture, the only thing out-of-place is that brown horizontal line towards the top.
Something weird: if you play for a few more screens-worth of the game, that weird brown line will actually line up with the tiles above it.

iq_132, I think the left-side clipping fix for Vendetta caused some right-side sprite clipping in X-Men.. uhoh.. :)  Gamez Fan found this one btw, its really easy to spot - load X-men, insert coin, select character, and watch the intro-cutscene on the right-hand side, sprites start to disapear prematurely.
