from the 0.277 whatsnew this jumps out as a candidate -Implemented specific SH3/SH4 chips & pass the required endian into the constructor, SH4 internal registers now work when using big endian. The debugger is now aware that the SH3/SH4 has an MMU. [smf] |

That would be commit: https://github.com/mamedev/mame/commit/b26662f1bba6809df145d9e8b3f78f66e3a7c7db#diff-6f5b5ca404e809dbf4327835e76b3de2f042f1d19f5d9ad3f907549d9e6c24ac That commit does change sega/dc.h which is included by sega/dc_atomiswave.h. It could be something else, but pointing out that you might be right. |

if somebody could confirm it's that then it would help narrow things down at least |

The game works, it just takes 5 minutes of a black screen before it suddenly springs to life. Also applies (at my last testing) to basschal, basschalo, xtrmhunt. vfurlong says NOW LOADING and then you have to wait the 5 minutes. |

weird, but still a regression, it shouldn't be taking 5 minutes to boot |

It is weird. I tried it again and held 'insert' key to speed up the wait time at around 375% and it did run after a minute or more. |

Noticed that kofnw and kofnwj no longer boot, stuck at black screen. Have to use -nodrc to play them. |
