Through BEX and Eternity extensions, support has also been added for a cleaner form of text substitution, default level par times, a more powerful method of codepointer editing, helper thing type editing, and better support for substitution of sprite, sound, and music names. | DeHackEd allows editing of things, frames, codepointers, ammo and weapon data, cheats, miscellaneous settings, and text strings.

However, none of this information is needed or used by Eternity in any way, and it is discarded as unrecognized text. You do not need to include any header information in your own files. Note that the patch version information is important for old patches in that it will tell you whether or not Eternity can use the file. Patches of format other than 6 are not guaranteed to work, and Eternity does NOT support the older, obsolete binary patch format. | However, none of this information is needed or used by Eternity in any way, and it is discarded as unrecognized text.
