Bugfix release, with the exception of adplug adding support for "Palladix" files.
- Not all systems provide memrchr, example are some MacOS/OSX variants.
- [adplug] Update to latest master
- This adds support for "Palladix" files.
- HERAD files were not working as expected.
- [sidplay] Update libsidplayfp to latest git version.
- [modland.com] If waitpid() returns a fatal error, give up waiting.
- [HVL] multiple updates:
- files with size below 4096 were not able to be detected on modland.com virtual drive.
- instrument-viewer must fetch the instruments from index 1, not 0.
- track-viewer must fetch global commands from the actual number of channels in use.
- reset the channel-information-cache on file-load, else we might try to dereference pointers from the previous song played.
- [MDL] In loader, the calculation of two buffer-sizes were missing parentheses, causing incorrect calculation.
