2015.11.25 "Bugs we didn’t see coming.." Sometimes it’s difficult to know if the emulation of a game is correct without studying reference videos, and sometimes those reference videos don’ t surface until much later. That was the case with the FACE shooter Nostradamus, which has a number of video effects we didn’t know were missing until they were highlighted by somebody watching a 1CC (1 Credit Clear) of the game recorded from a PCB. There were a number of effects, including a sprite masking effect and a shadow flicker effect missing, as well as the arms of the final boss (this one we did actually suspect was a bug for a long time, the PCB evidence provided confirmation) I’ve uploaded a recording of the game after making several fixes to YouTube (the video has cheats enabled, it’s not meant to be a gameplay video) You’ ll probably want to make sure you’re watching a 60fps version. https://www.youtube.com/watch?v=WyGfj4hJINI&feature=player_embedded Here are some links to specific parts of the video Stage 6 Boss appearing – This is a masking / stencil effect created by putting a sprite behind the background layer causing it to cut holes in other sprites without being directly visible https://www.youtube.com/watch?v=WyGfj4hJINI&feature=youtu.be&t=17m38s Stage 7 Boss appearing – This flickering shadow is not actually a sprite and is done by using the tilemap enable register, turning it on and off every few frames, previously the tilemaps were alwyas enabled and the shadow was displayed as solid. https://youtu.be/WyGfj4hJINI?t=19m38s Final Boss arms – The arms are priority 0 sprites, and due to the way we cleared the priority buffer to 0 they were never being displayed. https://youtu.be/WyGfj4hJINI?t=27m30s 來源 http://mamedev.emulab.it/haze/ -- 羅嘉仁(49) 右投右打(スリークォーター) 球威Ｃ 制球Ｅ スタミナＥ 球速１５７ 火の玉ボール 　荒れ球 ← → 責任感 速球中心 ↙ ↓ ↘ カープ チェンジアップ http://perry0517a.blogspot.tw/ --
