This was my better attempt in trying to make work Nightmare in the Dark on the Dreamcast
through Chui AES4ALL
this is the prebuilt .AES file, just add it in your game list and try it
tested on real hardware (DC), the graphic is absolutely ok
there is a strange bug in the music, that is cutted early and it loops continuously
sfx ok too
played until third boss, all ok here
let me know
if you need the emulator, is here :
