|
* MPTHacks.cpp
|
|
* ------------
|
|
* Purpose: Find out if MOD/XM/S3M/IT modules have MPT-specific hacks and fix them.
|
|
* Notes : This is not finished yet. Still need to handle:
|
|
* - Out-of-range sample pre-amp settings
|
|
* - Comments in XM files
|
|
* - Many auto-fix actions (so that the auto-fix mode can actually be used at some point!)
|
|
* Maybe there should be two options if hacks are found: Convert the song to MPTM or remove hacks.
|
|
* Authors: OpenMPT Devs
|

* The OpenMPT source code is released under the BSD license. Read LICENSE for more details.
