FPGA_1943 re-implements the famous arcade game from CAPCOM : 1943, the battle of midway.
Since the hardware is very close, games like Commando, Black Tiger, Gun Smoke or Side Arms could be supported.
- Uses the TV80 Z80 core.
- Very small implementation.
- Run out of one 16-bit SDRAM running at 72 MHz.
- One background 32x32 tile layer (16 colors).
- One foreground 32x32 tile layer (16 colors).
- One 8x8 character layer (4 colors).
- One sprite generator that handles 128 sprites (16 colors).
- Security chip is implemented.
- Two upscaling schemes : Scale2X or CRT grid with blooming (see the snapshots).
- The ROMs are not included with the core, graphics ones must be translated in a more core friendly format.
- Sound is missing :-(
