-OpenMoHAA supports any architecture, thanks to the CMake build system and cross-platform code/libraries. While the most common little-Endian architectures (arm, aarch64, x86, x86_64) have been tested and confirmed to work, big-Endian architectures should be supported as well; however, they remain untested.
