r18312 Saturday 6th October, 2012 at 16:39:12 UTC by Tafoid
Improved the graphic rendering a bit in blackt96, almost where it should be.  Sound still missing and other possible issues related to PIC that is not hooked up - any help there is appreciated.  From Haze (nw)
[src/mame/drivers]blackt96.c

5757each made of 1x32 tile strips, however the game only ever appears to use 3
5858banks of tile strips (96 sprites)
5959
60Priority isn't understood (other attributes, sort by y pos?)
60In practice it seems like the hardware can probably only draw these 3 banks
61as separate layers with seemingly hardcoded priority levels, despite the odd
62design.
6163
6264Furthermore there are two sets of graphics, background tiles and 'sprite'
6365tiles which are of different bitdepths, but are addressed in the same way.
6466
6567Tilemap hookup is just to make viewing easier, it's not used for rendering
6668
67
6869There is also an additional 8x8 text layer..

71
72Bugs:
73
74Sometimes if you attack an enemy when you're at the top of the screen they'll
75end up landing in an even higher position, and appear over the backgrounds!
76I think this is just a game bug..
77
78The timer doesn't work (PIC?, RAM Mirror?)
79
80There are some unmapped writes past the end of text ram too
