Okay, thanks to Bukster very kindly making a tweaked base version of the game, I've finally been able to implement my Galaga graphics hack. It comes in two versions - Standard and Fat Boiz, with chunkier graphics.

At some point I'm hoping to persuade him to make one that doesn't use 0 for the Boss Galagas so the scoreline doesn't get messed up

I was hoping for the same when I did my UDG version
Re: Tractor Beam - Galaga Edition
Changing the alien character codes isn't difficult. I can see the zero is the main problem. As you are replacing the character, it doesn't really matter what is used for each alien. It could be a question mark or a dollar sign and it wouldn't matter.
I'll have to check these out. Looks good.

Re: Tractor Beam - Galaga Edition
I suggest keeping the current version and creating another version specific to UDG, exchanging all alphanumeric characters for others so as not to disturb any text on the screen, even including the redefined characters.

Re: Tractor Beam - Galaga Edition
Sir Morris made two versions of Bigg oil one normal and one character coded so I could create a UDG version without spoiling the letter set. My version of Tractor beam does spoil the letter set sadly but I was pleased with the aliens though.
