I'm comparing Sega arcade games to their PC ports on YouTube, and am soon going to get to Buck Rogers - Planet of Zoom.
However, I've noticed that the z-index (or layering, or whatever it would have been referred to in 1982!) is a bit broken. I can't see any bugs in MAME Testers against turbo.cpp relating to this, and there are no MAME alerts of inaccurate graphics before the game begins.
These are the issues I noticed:
1. End of each stage: your ship disappears behind the growing blue warp effect.
2. Round 1 Sector 7 - enemy ships are drawn behind the distant mountains.
3. Round 1 Sector 8 - your ship appears ahead of the mothership, instead of behind it, making targeting it difficult!
There aren't many references of the real arcade out there, but I have found one where the blue warp effect clearly shows the ship in front of the blue area.
Compare this footage of the arcade (all 3 issues above are visible): https://www.youtube.com/watch?v=T-SrMyjljSM
to this of the real cabinet (only the blue warp is visible in this clip, but I suspect the same layering issue affects the mothership fight too): https://www.youtube.com/watch?v=6coJ4_xFvxY
I was wondering if this is a new bug, or whether it's always been like this in MAME, before I capture footage of the arcade version. UPDATE: see below, older versions have correct layering (though other bugs most likely!).
