What a mess.
The zzz file has a sort of zip-like structure at the beginning that refers to nothing.
While the wad has a similar structure at the end but the offsets don't match very well.
The other big problem is that compression is used but no idea about what algorithm.

The following is a work-in-progress script for reference (in short DO NOT USE IT!):

Code:

for i = 0
    findloc OFFSET binary "PK\x01\x02"
    math OFFSET   4
    goto OFFSET
    get DUMMY short
    get ver             short
    get flag            short
    get method          short
    get modtime         short
    get moddate         short
    get zip_crc         long
    get comp_size       long
    get uncomp_size     long
    get name_len        short
    getdstring ZERO 8
    get DUMMY short # 0x20
    get DUMMY short
    get OFFSET long
    getdstring name     name_len
    log NAME OFFSET comp_size
next i
