No.23464 Robbbert Moderator 2 days ago	Mostly it's ok, but in certain areas (such as in the screenshot) the crystals are showing before they should.
No.23467 hap Developer 2 days ago edited on: 1 day ago	It's this thing: m_bg_tilemap->set_transmask(2,0x00ff,0xff00); // for Japan message It smells like a workaround to me, for a different issue. Maybe MCU comms. I tweaked the transmask to make it work: https://github.com/mamedev/mame/commit/7c7e7cef68872bef0a3f38611745fc2f8aeebe8b I think the "erase the tilemap" command is from the MCU. But it fills it with the wrong value, causing the RAM/ROM OK and "for Japan" warning message to be obscured with the standard transmask (which is not a BTANB according to PCB videos).
No.23468 hap Developer 1 day ago	The ending sequence is still broken, even if I remove the workaround altogether. 33:25 in the video The retracting wall at the end of stage 5-1 is also broken. 21:30 in the video
No.23470 hap Developer 1 day ago edited on: 1 day ago	Ok, priorities look good now. There's still raster effect glitches (that I didn't see at all in the video), but that's not related to priorities. I think this bug, though the description is vague: https://mametesters.org/view.php?id=816
