I guess VBXE gets phi2 on antic socket, because is mounted over it.
I also tried by changing the 7408 Ic with a ls and f versions, and I have the same results. I’m trying to get a phi2 fixer to see if this could help as well.
p.s.: it seems that the graphics glitches come from the PMG overlay. The title and the moon could be using Player-Missile graphics.
