New to the community but learning a lot and trying to learn more.
I fell in love with a Galaxian cabinet at a barcade i frequented. High score on the board. I decided i wanted to get into arcade game collecting and purchased a Galaxian pcb on eBay. I knew that what i bought was "unmodified" other than a high score saver and that what i played was definitely hacked in some way (faster defending ship, increasingly faster enemies, increasingly more numerous enemies). I was able to get an employee to snap a couple pictures of the PCB and see that it has a daughter board where mine has empty sockets. I see a lot of references online about "daughter boards that were removed from Galaxians" but the original manual schematics show only sockets where the daughter boards often show up; like mine.
I'm trying to understand where the modifications would be installed on the barcade version (i assume the daughter board) and how i can obtain such mods for my PCB to install (i assume at the empty sockets).
Any information or pictures would be appreciated. I have built a table top control set for my board and have been playing it but want to get to the same gameplay as at the barcade.
(First picture is the barcade PCB and others are mine)
