/**************************************************************************** Mazer Blazer by Stern (c) 1983 Great Guns by Stern (c) 1983 Driver by Jarek Burczynski 2003.03.19 Issues: ====== Sprites leave trails in both ganes Sprites should be transparent (color 0x0f) Screen flickers heavily in Great Guns (double buffer issue?). TO DO: ===== - handle page flipping - figure out the VCU modes used in "clr_r": 0x13 -? sprites related 0x03 -? could be collision detection (if there is such a thing) - figure out how the palette is handled (partially done) - find out if there are any CLUTs (might be the other unknown cases in mode 7) - figure out what really should happen during VCU test in Great Guns (patched out at the moment) (btw. Mazer Blazer doesn't test VCU) - add sound to Mazer Blazer - Speech processor is unknown chip ****************************************************************************/ #include "driver.h" #include "cpu/z80/z80.h" #include "sound/ay8910.h" static UINT8 *cfb_ram;
