再現方法:
Opening visual scene. At one point, the sprite graphics of one of the planes is bad data. Also, noise is played through audio for a moment.
Seems to be bad data loaded into ADPCM and/or sprites (small amount) during opening scene.
これもシーク時間とロード時間の再現で直ると思います.
Maybe this is two separate issues.
ADPCM:
If I reduce the seek time on Mednafen to nearly zero (less than 13 milliseconds), I can make ADPCM noise appear.
Sprite graphics:
Even when I reduce the seek time on Mednafen to basically zero (0.0065 milliseconds), this never happens.
