You shoot at your enemies, who create different formations and attack you. Your movement in the spacecraft is limited to left and right movements. The goal of the Galaga game is to get as many points as possible and to defeat your enemies.
It is no wonder that even after more than thirty years it is still very popular and has been released on countless game consoles of all manufacturers. Your armed spaceship is at the bottom of the screen, and enemy aliens in the form of different spiders of flies, beetles and other creatures attack you from the top of the screen down. For those who have come across the game for the first time, it's a game where you have to bounce off the alien attack with your space ship. It is the precursor of all the plays and that is a fact !!!

What more could you ask for?Ī walkthrough tutorial? We’ve just given you one. (It’s not like trying to reverse engineer all however many jiggabytes of Microsoft Office.) The assembly languages for the old chips are small and well-documented, and most of the time you’ve also got a good dissasembler. Memory was expensive back then too, so the games themselves are small. If you’re at all interested in learning reverse engineering, go read ’s explanations and work through them on your own.Īnd here’s our generic plug for Computer Archaeology:Īncient video games run on MAME or similar emulators are the perfect playground for learning to reverse engineer you can pause the machine, flip a bit in memory, and watch what happens next. So that’s the punchline, but everyone knows that a good joke is in the telling. No further shots are fired in the entire game. The end result is that eight missiles get stuck in a place where they never drop and don’t get drawn.

Now two facts: there’s a maximum of eight missiles on the screen at any given time, and the position X=0 was reserved by the software to hide sprites that don’t need updating. While swooping, sometimes the bees will fire a shot when they’re at coordinates with X=0. When only six are left, they go into a second pattern where they swoop across the screen and wrap around the edges. The glitch is triggered by first killing most of the bees. Spoilers ahoy! Go read the website first if you’d like to follow ’s reversing efforts in the order that they actually happened. And so he did what any curious hacker would do - reverse-engineer the game to diagnose and eventually fix the bug. We didn’t know there was a cheat to Galaga, but did.
