Content type:	text/plain
Branch:	MAIN
Changes since 1.6:	+2 -0 lines
Log Message:	- imported fixed UAE FPU from Lauri - extfs.cpp: fixed bug with fsResolveWDCB in fs_get_wd_info() - ExtFS: MAX_PATH_LENGTH is global, removed third parameter to add_path_component() - rom_patches.cpp: added print_rom_info() - Unix: added "-rominfo" command line argument - extfs_unix.cpp: supports finder info and resource forks - prefs_editor_gtk.cpp: tab widget is no longer scrollable
