Lumps encroaching into the info table: allowed?

[printz]

Do modern Doom utilities like SLADE3 allow a lump to overlap the directory info table? This way, if you modify the contents of the lamp wherever the overlapped part of the table is, you'll also modify the structure of the wad, in a controlled manner.

Too bad this trick couldn't be done inside Doom because everything just gets loaded into memory.

No, not at all. It'd actually be rejected as a corrupted WAD.

[printz]

Same goes for lumps overlapping each other? Or lumps overlapping the header.

[Graf Zahl]

Of course. Why would you ever want to do such stuff? No lump manager could write it back reliably.
