I can confirm this bug. I just tested it on my v1.6 console modified VIA an Xecuter 2.6 CE modhip running the EvoX M8 v1.6 BIOS. The issue is the same regardless of dashboard. The temporary solution (until a fix is released of course) is to play the game in standard definition instead of 720p. This can be done by pressing start in the main CoinOPS 2 game list, choosing the Settings option, scrolling to the bottom of the list, enabling Advanced Settings, pressing the right trigger 1 time, and setting VIDEO 720P Hi Def Support to DISABLED. CoinOPS 2 will then restart in standard definition mode and DoDonPachi should work just fine. I hope that helps!
