Space Invaders, designed and programmed by Toshihiro Nishikado for Taito in 1978, was the first mainstream arcade game and remains one of the most popular ever made.
Here is a VHDL model of the Midway 8080 system and game boards. Including Space Invaders, Dog Patch and Sea Wolf.
The invaders_rel0300 release contains Space Invaders with audio and colour overlay and is targeted at the Spartan3E starter kit board. It also contains a simple scan doubler which converts the approx 15K line scan output to a 30K line rate suitable for VGA monitors. Sean Riddle has created a version which uses the external Strataflash on the board, and this allows 16 different games to be supported. See the Readme file in the distribution for details on the games and the build_invmulti_roms.bat file for the roms needed.
