Namco Galaga Compatible Gateware IP Core
This Implementation of a compatible Galaga arcade hardware in HDL is the work of Dar.
Galaga is a single-screen shoot-em-up in which the player controls a 'Fighter' spaceship and must defend the home planet against the on-coming hordes of alien invaders called "Galagans". The Fighter can only move left and right along the bottom of the screen.
Galagans fly onto the screen in a variety of formations before forming troop lines at the top of the screen. Once all troop lines are formed the Galagans separate and start attacking the player's Fighter in ones, twos and threes. The top-line Boss Galaga need to be shot twice before they are destroyed.
The Boss Galaga has a tractor beam that can capture the player's Fighter. A captured Fighter changes color from white to red and stays with that particular Boss until it is destroyed. The Fighter can be retrieved by destroying the Boss that captured it, but players must be careful not to destroy the captured Fighter itself, or that Fighter is lost. A rescued Fighter changes color back to white and links up with the player's current Fighter, doubling its fire power.

- Hi-Score Save
- A bug in the sound CPU program. During initialization, it enables NMI before clearing RAM, but the NMI handler doesn't save the registers, so it cannot interrupt program execution. If the NMI happens before the LDIR that clears RAM has finished, the program will crash.1
