AFAIK SNDH playback uses the SC68 lib. And it's a piece of cake to create an SNDH file on the ST, since there is a nifty tool for it. That's what made me think that something like this could exist for SC68 files too. Thanks for explanation mate, I'm - even if I'm probably never ever gonna be able to do it myself - enlightened now about the creation of SC68 files.

well, SC68 is not a file format for storing sound/music. It really is an emulator for 68000 along with the emulation of the audio chipset of the Atari and the Amiga (well, almost 100%).
In any cases it runs the native 68000 code, unlike the other libs mentioned. That's why it's not so "easy" to create a SC68 file.
I almost use SC68 for every tune (except MOD files) because on the Amiga there are lots of different replay routines and tons of "custom" and "synth" music formats, that have never been ported to PC (AFAIK only 2 or 3 like FutureComposer, AHX and SoundMonitor had a replay routine on PC). So in most cases, the only way is to emulate the original replay routine (which sometimes has to be ripped off the original binary because the source code has been lost, see the music for the game Hybris for example...) http://www.retro-remakes.net

Yup, thx I know that. I used it in my first TEX remake. But usually SNDH and SC68 playback sounds much better than YM because it sometimes misses a lot of music information due to the way it's created. But it's okay most of the songs are available in SNDH (or at least convertable into) anyway. It's just that I've been curious if there was an easy way to create an SC68 file in case some format couldn't be converted into SNDH.

probably you know about this already, but for Atari music, this is a good alternative to SC68:

Fair enough. I know that site. I'm probably too stupid to figure it out at the moment then. haha I thought there'd be an easy way to do that, just like creating SNDH files. Nevertheless thanks guys!

yeah, that's the only documentation available..
http://sc68.atari.org/developers_fileformat.html
basically a SC68 file is a structured file using chunks of data (id/length/data packets)
The replay routine can be embedded in the file or separate. I prefer when it's embedded because you don't have issues with playing a tune then.. but makes the file a few bytes larger of course (who cares now???)
There is a chunk that specifies the start of the actual 68000 data. If the replay routine is embedded, then the first bytes of the actual 68000 data are:
BRA.W music_init
BRA.W music_end
BRA.W music_play
music_xxx are of course memory addresses to the replay init/stop/play routines.
You need to know a bit of 68000 asm to play with these, but it's not that difficult. Have a look at some of the tunes provided with the distribution using a hex editor and a disassembler... http://www.retro-remakes.net

I never managed to create an SC68 file. Is there a tutorial somewhere?

@rbz: hmm... one way would be to pack it along with the original replay routine and create a SC68 binary for the emulator http://www.retro-remakes.net

Btw, anyone here can convert this .mod song Link into fasttracker format (.xm) without loosing stereo separation. I've tried to convert it with using madtracker, skaletracker, milktracker and mod2xm without any success, it always sound different from module format :/

I hope no one else is remaking this one -> Link because I just need to recode a rainbow color bar (or whatever it's called)...
