MCOL sits beside REGN in hidden/MiscBin.pak, 11 of each, never decoded. Over all 11: POF0 at data_size+16 11/11, bbox pad words 1.0/1.0/0.0 11/11, and extent == max-min 11/11. So the header prefix is the same shape as REGN's and the POF0 mechanism applies, which means the chunk+0x10 base and the loader's own pointer list -- the two things that cracked REGN -- are available here too. The map parameters are not merely similar but identical in distribution: bboxes 2/6/3 at 250k/50k/25k and the 0x40 triple 2 at 50000 and 9 at 10000, matching REGN exactly. Eleven maps, each with an MCOL and a REGN over the same volume at the same cell size. Noted that this matches distributions, not a demonstrated object-to-object pairing. Everything past 0x40 diverges from REGN and is open. Also recorded that my own POF0 delta decoder is wrong here -- eight leading zero deltas -- and that the working one is regn_decode.py on auto/regn-reader, which should be used rather than re-derived. Re-deriving it is the mistake I made.
