how to create my own IWAD?

[S.N.]

hello, I have a small pending project and I would like that you explained a thing to me: as I can create my own IWAD or modify one existing one and that works? a long time ago I obtained it but nonmemory like, I use Wintex and am beginning with XWE, somebody can help me please.

P.D.: I write these post with a translator, so not if they will leave absolutely well XP

An IWAD is just a PWAD with an "I" instead of a "P" as first byte in the file. Some tools can convert PWADs to IWADs and vice versa, but you can also easily do it manually with a hex editor.

Some ports won't even care if the header says I or P, just as long as all the lumps it needs are present.

Freedoom is built using deutex, which has a '-iwad' parameter to build an IWAD instead of a PWAD.

Thank you very much by the information, although I even have some doubts (I am inexperienced XP):

It is for using with exe of the own Doom, would have to work equal, no?

I know what you mean, I feel much so heavy being sometimes too.
