Bill has given permission years ago for MAME or any other emulator/simulator to use his game, but the problem was it was only available as PDF, after I spent a few months converting the PDF to a compilable code and then error checking, I did get some help error checking the code.
The Source code for Galaxy Game Source is available, original and modified source code. I did have to change the Octal numbers and .ASCII to a different compiler to get a absolute address version, the first compiler wanted to create relocatable code. The code will compile to almost the same binary, the problem is 1 opcode which when Bill compiled it, show the wrong Octal code on listing. Bill thinks the problem is a line printer error or thats how the Compiler back in '71 compiled the code.
The PDP-11 which is what Galaxy Game CPU is the almost the same as the T-11 CPU which is MAME currently. The T-11 CPU is a PDP-11 on a chip. The OpCodes (986 in Galaxy Game) used which are available in the T-11. So it shouldn't be that hard to get Galaxy Game to run in MAME.
