Ok, the problem is that, on european model2, the game wont play music from title screen and will play music from panel menu ... I think its a wierd and dangerous behaviour.
I'll ship the game in 18hours... I'll add myself CD sound volume control...
For the audio bug.. well if you can fix it within 18hours, okay... Anyway i'll try to fix myself (even if i gens doesn't have appropriate debug mode).
For the shiping, the game BGM is nearly 60MB in mp3, so i prefer to send directly final burned disc (using fastest shipping method).
EDIT, i pmed you the url to grab the files (cdread.asm too).
I edited things, now the cdopentray operation is replaced by music stop (and it works).
Please read instructions about how to check if cdvolume is really working.
Thx
Fonzie
