Hello all.
I have this archive of suspected obscurity. I suspect it contains what i'm looking for (.tm2 images inside)
That is simply not a tm2 file, but a .as7 I suspect it's just more an archive of tm2 files. I've tried to extract the tm2 files with TextER from here: https://www.romhacking.net/utilities/659/
This tool scan a file in search for tm2 files. But it does not with this archive.

I later suspect this archive might be very well compressed, and then the tm2 inside cannot be opened directly. I;ve been searching for ways to decompress them, in this case.
I've come to know that there are 12 .tm2 inside whtf with the hex editor, seen by the .tm2 header. (12 detected inside).

How would I go about decompressing archives (any archive really) in this case, any specific values to search for? I should be able to experiment around the pieces with some starting point tips.

This format doesn't seem to have much sense since the sequence of offsets includes both TIM and random data, anyway:
endian big
idstring "A7"
get FILES short
get AS7_SIZE long
for i = 0 < FILES
    get OFFSET long
    putarray 0 i OFFSET
next i
    putarray 0 i AS7_SIZE
for i = 0 < FILES
    getarray OFFSET 0 i
    math i + 1
    getarray SIZE   0 i
    math SIZE - OFFSET
    log "" OFFSET SIZE
