11 Issues:
12 ======
13 Sprites leave trails in both ganes
14 Sprites should be transparent (color 0x0f)
15 Screen flickers heavily in Great Guns (double buffer issue?).
16
17
18 TO DO:
19 =====
20 - handle page flipping
21
22 - figure out the VCU modes used in "clr_r":
23 0x13 -? sprites related
24 0x03 -? could be collision detection (if there is such a thing)
25
26 - figure out how the palette is handled (partially done)
27
28 - find out if there are any CLUTs (might be the other unknown cases in mode 7)
29
30 - figure out what really should happen during VCU test in Great Guns (patched
31 out at the moment) (btw. Mazer Blazer doesn't test VCU)
32
33 - add sound to Mazer Blazer - Speech processor is unknown chip
