The file includes only the patch, not an ips patch program. ZSNES has had internal support for IPS files a long time now... SMC.COM is also included, for checking purposes.
Keep in mind that while enhancement patches are not considered illegal, distribution of commercial game ROMs is. Therefore, the file DOES NOT include the actual Secret of Mana game ROM. I suggest you check a search engine for other sites that may contain emulators and/or ROMs.
If you don't have a program to apply IPS patches, try
