Ninja Gaiden [NES] + R2RKMF: Scrolling Action Monogatari

[BrianC]

Anyway, the reason that I am here is because I have a question that I know someone knows the answer to. What is wrong with arcade Contra on the Anniversary Collection? I know that the emulation on it is messed up somewhere and somehow, and that ACA has either the first or the only accurate emulation of the game, but I don't know what the problem is or if it's something to even care about.

The issue is that the behavior of the rollers in the maze stages was incorrect. They were swerving diagonally instead of moving straight. For a while, ACA was the only place that had it fixed, but the issue was found and corrected more recently for the MAME and FPGA versions, as well. I think it was one of the MCU chips not being well documented or something along those lines.
