There are tons of issues with Vampire’s AGA implementation, unfortunately. MiST and MiSTer get it right on the FPGA front, Vampire’s implementation isn’t great.
Probably You don't have an Apollo Board, or you never get updated it. Nowadays there are very few games that have issues, but this isn't the fault of the card and its amazing features, but rather, more often, the fault of poorly programmed games from the past. Certainly, some WHDLoad slaves should be fixed for the Apollo V4 as well, but that's another story.
What I often hear is just a denigration of the Apollo card. Without any polemical intent.
