New Revision: 20618
URL: https://source.openmpt.org/browse/openmpt/?op=revision&rev=20618
Log:
[New] Can now load ChipTracker modules, another SoundTracker clone using a track-based approach. As it shares the typical MOD sample structures, it is also placed in Load_mod.cpp.

+ * Purpose: MOD / NST (ProTracker / NoiseTracker), M15 / STK (Ultimate Soundtracker / Soundtracker), ST26 (SoundTracker 2.6 / Ice Tracker) and ChipTracker module loader / saver
* Notes : "2000 LOC for processing MOD files?!" you say? Well, this file also contains loaders for some formats that are almost identical to MOD, and extensive
* heuristics for more or less broken MOD files and files saved with tons of different trackers, to allow for the most optimal playback.
