Let me explain, current:

right powerbar, 3 segments, LCD pin Y.
right weapon pickup, LCD pin Y.

Swapped:
left powerbar, 3 segments, LCD pin Y.
left weapon pickup, LCD pin X

right powerbar, 3 segments, LCD pin X.
right weapon pickup, LCD pin Y.

This would mean the LCD pin traces of X/Y get crossed, it's not possible on a 1-layer LCD panel.
Here, my annoyance is not large, I can still joke about it:


I have the original device, and this doesn't look like a MAME bug. Just been testing... horrible game, and weapon and energy do appear to be the wrong way round, but that would be accurate to real hardware. Hope this helps - let me know if more evidence is needed.
