That is entirely possible. It may well be that the sprite coordinates are not placed exactly where they should be. Early hardware had known nuances with some (eg. 1 or 2) sprites being offset a few pixels with respect to the other sprites. In fact, I'm currently working on Frogger (same hardware) and did have to tweak the sprite routines that I lifted from Galaxian; Frogger has the advantage in that the background can be used as a reference, though of course the background is also subject to its own nuances. I'll finish up on Frogger and revisit Galaxian to see if there are any changes I should back-port.
I'm also thinking it may be possible to implement a non-tate mode for Galaxian as well!
Working great on 4 slot mvs/neo sd pro! Thank you, Any chance of non tate mode for this & xevious? I'm playing on a horizontal setup & these are the only "vertical" games on the cab
Xevious, doubtful. I've tried to think how scrolling would work in non tate mode, but I just don't see how it could be done. But maybe I just need to think about it again after coming back from a break. Will need scaling to fit the entire screen though...
Galaxian, maybe. Similar issue to Xevious, but less demanding. I'll think about it.

Awesome work.

Hi there, I hope you don't mind, but I have included Galaxian in with the best Neo Geo homebrew games of all time.
Nice, thanks!
No probs

Sounds good, thank you!
Added (untested on real hardware)
Tested on MiSTer fpga. It works great!!
