Summary 06868: dkong: Video rendering is not cycle accurate or accounting for all bus factors.
Description Simply put, the video output for this game, which also effects many different machines' emulated output, alters the way the game is presented on screen at a frame by frame level. A specific and easily visible issue is that the latest version of MAME emulates this scan from right to left instead of from left to right like an actual arcade Donkey Kong does, so the timing information is opposite.

Further details are available as tests were done from MAME recordings, Arcade PCB output sources.
