The IPS Patch Format is a common format for simpler hacks. It generally does basic patching but works well enough. There are two main IPS patchers: Lunar IPS and IPS Win 2.0. There is also a 3rd unique IPS patcher called SPATCH which uses two IPS patches for the game.

IPS Patchers are generally quite simple as loading the original ROM, the patch, and telling the patcher where your new game will be, as well as what it is called. For SPATCH, you will sometimes need to select two patches instead of one, depending on the creator and whether they used the one-patch format or the two-patch format. Patches/hacks should contain more in-depth tutorials on how to patch files with IPS patchers.
