The names are NX2NAVI, NX2navi or nx2navi: the settings prefix (NX2NAVI_*), the ini file (nx2navi.ini), the shader translator (nx2navi_xlate), the Windows resources, the installer and the docs. The 8-byte file magics keep their size (NX2NSANS, NX2NSPRG, NX2NSPRP, NX2NPKEY, NX2NRFS1), so caches and the RomFS index from older builds are not read. cfg.c and the settings pages took the prefix length as 5; it now follows the prefix.
