This is an easy to fit multi-game hack for standard Galaxians PCB's (upright or cocktail). It currently allows you to select from up to 18 different games.
It uses plug in daughter boards that make fitting much easier. Best case will require a single wire to be soldered, worst case will require you to remove the colour prom and fit a socket there as well.

INSTALLED ON PCB
PLUG IN PCB
Fitted to galaxian PCB. This is the latest version. now uses IDC connectors since they are much easier to make
As can be seen on the right hand screenshot, the default to return to menu is to press both Start 1 and Start 2 together. This works well along with Freeplay on the coin selection. If you wish to use coins to play the games, it is recommended that you add the optional 'Return to Menu' button.
Galaxian, but now with a top 5 high score table so you can keep a record of all of those record scores for everyone to try and beat!
Moon Cresta, another really good shoot'em up
Omega, an excellent French variation on the game more commonly known as The End. I had always been a fan of the original, and I have played both quite a bit now, and I'm beginning to prefer this version. There are a few differences that make it that little bit more challenging.
Another all time classic. The sideways scrolling, multi-leveled Scramble.
It's another all time favourite, but this time from the guys at Armenia and called War of the Bugs. This one has the single high score name saved and kept for all to see.
Take galaxian, add some extra tweaks, bendy bullets, turbo charged alien swarms, and what you end up with is something like Galaxian Part X. From all of the various hacks, this one retains the playability of the original, but increases the challenge.
Black hole makes a return. This time I discovered that the game was in fact a bootleg, so we still don't know who was responsible for this masterpiece of programming.
Lady Bug is another of the new games to grace our multigame. Along with Scramble and War of the Bugs, the reason you need to wire up those additional Up and Down buttons.
Uniwars makes the transition from the previous multigame to become number 9 in the lineup. Single named high score added, all the other bits are in there, shared coinage, DIP settings.
Frog sneaks in at number 10, having had to avoid various obstacles on the way. A fair amount of changes to this one, the most obvious being the correct colours. Other changes and fixes include correct musical scales so the tunes sound much better (thanks Ivan), top 5 named scores and the normal software settings.
Since Ivan helped with some fixes to the last game, it seemed time that I managed to add his custom written game into the system.
Mr Do's Nightmare is now installed in it's rightful place, and I even managed to get the apostrophe in the menu. There's about a dozen screens to see, and so far I've not made it past the fifth one, so it would appear to be quite challenging. (and apparently, there's a bonus screen as well)
Video Pool moves into the number 12 slot, makes a change from all the frantic shooting games, although, of course, you still get to try for the pot shots. Usual features included, but only a single named high score (I'm running out of battery backed ram to use) so the normal high score table has been converted to 'Todays Best' in the vein of Williams games.
The thirteenth game moves into position, and this is another favourite from the previous multigame, it's Pisces. Another multi-screen shoot'em up with a lunar lander section as well to keep you on your toes. Normal changes are in there, DIP switches, invert switch, single named high score.
Devil fish, the game I had most requests for makes it into fourteenth place. A couple of unexpected changes to this one, the first to make it work on an unmodified galaxian board at all, now that surprised me to start with, all of the Artic games I've ever seen were part of their cartridge system, but this one uses a different interrupt method to normal, and I cannot remember seeing any additional wiring that would implement this? - oh well, here it is for 'normal' galaxian boards. Most of the normal changes, software DIPs, common coinage, invert switch, but this time you only get the single high score and not even a name entry (there is no spare room to add the necessary code into the program!)
Exodus is the final game from the 8 game version to move across into the newer multigame. All 8 are now included, which means the 16th game is something totally different (hint - jump!) This game has all of the normal tweaks, software DIP settings, shared coinage, orientation and the single named high score entry.
The final game in the lineup is Amidar, this game has had most of the normal tweaks made to it, software DIPS, shared coinage, orientation, but this game only saves the 3 highest scores. No names since the character set doesn't include the entire alphabet!
I've been meaning to add some extra games to the multigame for a while, and received a request to add Moon Alien 2. Big difference from normal galaxian is the addition of the energy bar, so you now have to clear the levels against the clock. All of the things you now expect from anything in the multigame, this time with single named high score entry.
Another game creeps in to join the others, this time it's a fun maze game from Jaleco called Dingo. It's harder than it looks, but I've almost worked out a fool proof way to clear the screen and avoid the Dingo's.
Not totally complete, as I have not yet sorted out the high score saving, and I also had a wicked idea to try on the back ground stars, but another playable game joins in the fun. Super Invader Attack. originally from Zaccaria joins the line up. It's a variant of the classic Space Invaders theme and is one of the hardest to play (if you have the homing missile enabled it follows you so that you can no longer hide below the bases)
