Merci à TOUS,
je pensais pas que dans ce format il y'avait le code integrer 68K pour le jouer sur st (vu qu'on peux le jouer sur pc).
Ok,merci dma-sc, j'ai trouver dans le txt de ton lien
MUSIC +$0 = branch here for music initialise routine
MUSIC +$4 = branch here for music de-initialise routine
MUSIC +$8 = branch here for music interrupt routine
MUSIC +$C (binary replayer) = read here for demo zynchronisation byte
+$B8 (unmodified SNDH)
+$?? (modified SNDH - byte is present directly after HDNS tag)
super!
Cordialement.
j'ajoute..
J'ai regardé ton dernier lien, exactement ce que je cherchais.
encore une fois merci.
Cordialement.
bonsoir,
j'ai essayer de dessambler un sndh avec ida, et ça merde....
j'ai vu que l'entete est ice! (compresser ?)
j'ai chercher et j'ai trouver:
the audio format for "SNDH Atari ST music" is checked by the string "ICE!"
But ICE is a file packer on the AtariST platform which can pack any data.
If you unpack the ICE format, you get the real SNDH file which can be identified with
12 string SNDH uncompressed atari SNDH music file
If you want to keep the ICE! definition to say it's SNDH that's fine, but please add SNDH uncompressed as I showed above.
One sugestions would be to add this, which works in 62% of cases for compressed SNDH:
0 string ICE! atari ICE packed data
>14 search/40 NDH SNDH music file
>14 search/40 TITL SNDH music file
The second search is needed because ICE sometimes packes the NDH string too well, but it still shows the TITL tag :-)
The rest 28% of files I found are very probably not in a proper SNDH format. They are just compatible with the player but lack a proper header. Others are packed *twice* with the ICE packer. For this I will make a bug report to the maintainer of the SNDH files archive.
TOUJOURS A CHERCHER A DESSASSEMBLER LE SNDH, qqun aurait une idee ?
je trouve pas les BRA au debut
merci
cordialement.
merci dma-sc,
je vais chercher ce week-end avec les infos que tu m'as donné.
Désolé pour les majuscule, c'etait pour bien marquer la separation du copier/coller avec ce que j'ecrit.
cordialement.
