No.23078 hap Developer 31 days ago edited on: 31 days ago	Regression from https://github.com/mamedev/mame/commit/0155ffe4c2d2c9647d14e3e3e099190d5588dcfb This PR: https://github.com/mamedev/mame/pull/13328 Specifically, the shadow flags change in metamrph_sprite_callback. I tried removing K055555_SKIPSHADOW for this game, but that brings back the fireworks bug when finishing stage 2 where the green guy says "so long suckers".
