maak: the munch.py "compressed" .it's are accepted to the BOTB compos (have used that few times myself), but it may cause compatibility problems for some players. E.g. Open MPT and latest versions of Xmplay should play the munch.py treated files fine
OK, I understand , thanks .
The next opportunity I'm going to try the use of munch.py. ( I of course want to check in XMPlay or OpenMPT.)
Thank you to information :D
